76-608: The Congress Theater is a historic movie palace in the Logan Square neighborhood of Chicago . Fridstein and Company designed it in 1926 for the movie theater operator Lubliner and Trinz . It features ornate exterior and interior design work in a combination of the Classical Revival and Italian Renaissance styles. It was listed on the National Register of Historic Places in 2017. In its heyday,

152-406: A photographic film . This was used commercially as "celluloid", a highly flammable plastic that until the mid-20th century formed the basis for lacquers and photographic film. On May 2, 1887, Hannibal Goodwin filed a patent for "a photographic pellicle and process of producing same ... especially in connection with roller cameras", but the patent was not granted until September 13, 1898. In

228-456: A box by the door to service as a ticket office (literally, the "box office".) Storefront theatres, supplied with motion pictures made in Chicago and New York, spread throughout America. These theatres exhibited a motion picture at a specific time during the day. Air domes also became popular in warm climates and in the summertime in northern climates. With no roof and only side walls or fences,

304-596: A broken heating pipe at the Cleveland Clinic in Ohio . That tragedy claimed 123 lives during the fire and additional fatalities several days later, when hospitalized victims died due to inhaling excessive amounts of smoke from the burning film, which was laced with toxic gases such as sulfur dioxide and hydrogen cyanide . Related fires in other medical facilities prompted the growing disuse of nitrocellulose stock for X-rays by 1933, nearly two decades before its use

380-458: A cotton apron, and wiped it up. He hung the apron on the stove door to dry, and as soon as it was dry, a flash occurred as the apron ignited. His preparation method was the first to be widely used. The method was to immerse one part of fine cotton in 15 parts of an equal blend of sulfuric acid and nitric acid. After two minutes, the cotton was removed and washed in cold water to set the esterification level and to remove all acid residue. The cotton

456-781: A fantasy environment to attract moviegoers and involved a type of social engineering, distraction, and traffic management, meant to work on human bodies and minds in a specific way. Today, most of the surviving movie palaces operate as regular theaters, showcasing concerts, plays and operas. This is a list of selected movie palaces, with location and year of construction. See also Nitrate film ( C 6 H 8 (NO 2 ) 2 O 5 ) n (dinitrocellulose) ( C 6 H 7 (NO 2 ) 3 O 5 ) n (trinitrocellulose, pictured in structures above) Nitrocellulose (also known as cellulose nitrate , flash paper , flash cotton , guncotton , pyroxylin and flash string , depending on form)

532-407: A flame. For this reason, immersing burning film in water may not extinguish it, and could actually increase the amount of smoke produced. Owing to public safety precautions, London Underground forbade transport of movies on its system until well past the introduction of safety film. Cinema fires caused by the ignition of nitrocellulose film stock commonly occurred as well. In Ireland in 1926, it

608-422: A hard finish with a deep lustre. It is normally the first coat applied, then it is sanded and followed by other coatings that bond to it. Nail polish contains nitrocellulose, as it is inexpensive, dries quickly to a hard film, and does not damage skin. The explosive applications are diverse and nitrate content is typically higher for propellant applications than for coatings. For space flight, nitrocellulose

684-524: A nitrate base in the west, but rumors exist of 16 mm nitrate film having been produced in the former Soviet Union and China. Nitrate dominated the market for professional-use 35 mm motion picture film from the industry's origins to the early 1950s. While cellulose acetate-based safety film, notably cellulose diacetate and cellulose acetate propionate, was produced in the gauge for small-scale use in niche applications (such as printing advertisements and other short films to enable them to be sent through

760-591: A notoriously tough security team, and lax building upkeep. In early 2014, Carranza announced he would sell the theater to developer Michael Moyer. Moyer planned to spend $ 65 million restoring the theater, with the goal of reopening the Congress in 2019. This plan, now under the ownership of Baum Revision, was approved by the City's Permit Review Committee in June, 2022 and by the full City Council on July 19, 2023. The budget

836-653: A number of reasons including environmental regulation and the cost of application vs. "poly" finishes. However, Gibson still use nitrocellulose lacquers on all of their guitars, as well as Fender when reproducing historically accurate guitars. The nitrocellulose lacquer yellows and cracks over time, and custom shops will reproduce this aging to make instruments appear vintage. Guitars made by smaller shops (luthiers) also often use "nitro" as it has an almost mythical status among guitarists. Because of its explosive nature, not all applications of nitrocellulose were successful. In 1869, with elephants having been poached to near extinction,

912-531: A projectile driver, it had around six times the gas generation of an equal volume of black powder and produced less smoke and less heating. Artillery shells filled with gun cotton were widely used during the American Civil War , and its use was one of the reasons the conflict was seen as the "first modern war." In combination with breech-loading artillery , such high explosive shells could cause greater damage than previous solid cannonballs. During

988-471: A small part of vaudeville theatres. The competitive vaudeville theatre market caused owners to constantly look for new entertainment, and the motion picture helped create demand, although the new form of entertainment was not the main draw for patrons. It was often used as a "chaser"—shown as the end of the performance to chase the audience from the theatre. These theatres were designed much like legitimate theatres. The Beaux-Arts architecture of these theatres

1064-409: A variety of referenced visual styles collided wildly with one another. French Baroque, High Gothic, Moroccan, Mediterranean, Spanish Gothic, Hindu, Babylonian, Aztec, Mayan, Orientalist, Italian Renaissance, and (after the discovery of King Tut 's tomb in 1922) Egyptian Revival were all variously mixed and matched. This wealth of ornament was not merely for aesthetic effect. It was meant to create

1140-431: Is a highly flammable compound formed by nitrating cellulose through exposure to a mixture of nitric acid and sulfuric acid . One of its first major uses was as guncotton, a replacement for gunpowder as propellant in firearms. It was also used to replace gunpowder as a low-order explosive in mining and other applications. In the form of collodion it was also a critical component in an early photographic emulsion,

1216-453: Is for the production of lacquers and coatings, explosives, and celluloid . In terms of lacquers and coatings, nitrocellulose dissolves readily in organic solvents, which upon evaporation leave a colorless, transparent, flexible film. Nitrocellulose lacquers have been used as a finish on furniture and musical instruments. Guncotton, dissolved at about 25% in acetone , forms a lacquer used in preliminary stages of wood finishing to develop

1292-431: Is less prone to stretching than other available plastics. By the late 1990s, polyester had almost entirely superseded triacetate for the production of intermediate elements and release prints. Triacetate remains in use for most camera negative stocks because it can be "invisibly" spliced using solvents during negative assembly, while polyester film is usually spliced using adhesive tape patches, which leave visible marks in

1368-435: Is much more resistant to polymer degradation than either nitrate or triacetate. Although triacetate does not decompose in as dangerous a way as nitrate does, it is still subject to a process known as deacetylation, often nicknamed "vinegar syndrome" (due to the acetic acid smell of decomposing film) by archivists, which causes the film to shrink, deform, become brittle and eventually unusable. PET, like cellulose mononitrate,

1444-434: Is not a nitro compound , but a nitrate ester . The glucose repeat unit (anhydroglucose) within the cellulose chain has three OH groups, each of which can form a nitrate ester. Thus, nitrocellulose can denote mononitrocellulose , dinitrocellulose , and trinitrocellulose , or a mixture thereof. With fewer OH groups than the parent cellulose, nitrocelluloses do not aggregate by hydrogen bonding . The overarching consequence

1520-751: Is reported to be $ 88 million, including $ 27 million in Tax Increment Funding. Movie palace There are three architectural design types of movie palaces: the classical-style movie palace, with opulent, luxurious architecture; the atmospheric theatre , which has an auditorium ceiling that resembles an open sky as a defining feature; and the Art Deco theaters that became popular in the 1930s. Paid exhibition of motion pictures began on April 14, 1894, at Andrew M. Holland's phonograph store, located at 1155 Broadway in New York City , with

1596-494: Is soluble in a mixture of ethanol and ether until nitrogen concentration exceeds 12%. Soluble nitrocellulose, or a solution thereof, is sometimes called collodion . Guncotton containing more than 13% nitrogen (sometimes called insoluble nitrocellulose) was prepared by prolonged exposure to hot, concentrated acids for limited use as a blasting explosive or for warheads of underwater weapons such as naval mines and torpedoes . Safe and sustained production of guncotton began at

1672-459: Is that the nitrocellulose is soluble in organic solvents such as acetone and esters; e.g., ethyl acetate , methyl acetate , ethyl carbonate . Most lacquers are prepared from the dinitrate, whereas explosives are mainly the trinitrate. The chemical equation for the formation of the trinitrate is The yields are about 85%, with losses attributed to complete oxidation of the cellulose to oxalic acid . The principal uses of cellulose nitrate

1748-562: The Chicago firm of Rapp and Rapp , which designed the Chicago , Uptown , and Oriental Theatres . S.L. "Roxy" Rothafel , originated the deluxe presentation of films with themed stage shows. Sid Grauman , built the first movie palace on the West Coast , Los Angeles' Million Dollar Theater , in 1918. Following World War II movie ticket sales began to rapidly decline due to the widespread adoption of television and mass migration of

1824-731: The Edison Company at another location on December 9, at its film-processing complex in West Orange, New Jersey . That catastrophic fire started inside a film-inspection building and caused over $ 7,000,000 in property damages ($ 213,000,000 today). Even after film technology changed, archives of older films remained vulnerable; the 1965 MGM vault fire burned many films that were decades old. The use of volatile nitrocellulose film for motion pictures led many cinemas to fireproof their projection rooms with wall coverings made of asbestos . Those additions intended to prevent or at least delay

1900-577: The Kinetoscope . Dropping a nickel in a machine allowed a viewer to see a short motion picture, devoid of plot. The machines were installed in Kinetoscope parlors, hotels, department stores , bars and drugstores in large American cities. The machines were popular from 1894 to 1896, but by the turn of the century had almost disappeared as Americans rejected the solitary viewing experience and boring entertainment. Around 1900, motion pictures became

1976-598: The Paris Exhibition of 1889 . Commercial production started in 1891, but the result was flammable and more expensive than cellulose acetate or cuprammonium rayon. Because of this predicament, production ceased early in the 1900s. Nitrocellulose was briefly known as "mother-in-law silk". Frank Hastings Griffin invented the double-godet, a special stretch-spinning process that changed artificial silk to rayon, rendering it usable in many industrial products such as tire cords and clothing. Nathan Rosenstein invented

2052-574: The Waltham Abbey Royal Gunpowder Mills in the 1860s, and the material rapidly became the dominant explosive, becoming the standard for military warheads, although it remained too potent to be used as a propellant. More-stable and slower-burning collodion mixtures were eventually prepared using less concentrated acids at lower temperatures for smokeless powder in firearms . The first practical smokeless powder made from nitrocellulose, for firearms and artillery ammunition,

2128-482: The billiards industry offered a US$ 10,000 prize to whoever came up with the best replacement for ivory billiard balls . John Wesley Hyatt created the winning replacement, which he created with a new material he invented, called camphored nitrocellulose—the first thermoplastic , better known as celluloid . The invention enjoyed a brief popularity, but the Hyatt balls were extremely flammable, and sometimes portions of

2204-461: The "spunize process" by which he turned rayon from a hard fiber to a fabric. This allowed rayon to become a popular raw material in textiles. Nitrocellulose lacquer manufactured by (among others) DuPont , was the primary material for painting automobiles for many years. Durability of finish, complexities of "multiple stage" modern finishes, and other factors including environmental regulation led manufacturers to choose newer technologies. It remained

2280-425: The 1900s and 1910s. As motion pictures developed as an art form, theatre infrastructure needed to change. Storefront theatres and nickelodeons catered to the busy work lives and limited budgets of the lower and middle classes. Motion pictures were generally only thought to be for the lower classes at that time as they were simple, short, and cost only five cents to attend. While the middle class regularly began to attend

2356-664: The Bronx. On May 13, a fire at Universal Pictures ' Colonial Hall "film factory" in Manhattan consumed another extensive collection. Yet again, on June 13 in Philadelphia, a fire and a series of explosions ignited inside the 186-square-meter (2,000-square-foot) film vault of the Lubin Manufacturing Company and quickly wiped out virtually all of that studio's pre-1914 catalogue. Then a second fire hit

2432-526: The Congress Theater could seat over 2,904 moviegoers. The theater block also had 17 retail storefronts with 56 apartments above. More recently, the theater operated as a 3,500-capacity live music venue. For years the building was a common and popular concert venue. In April 2013, the theater was shut down and had its liquor license revoked due to numerous safety code violations. It was a source of controversy due to issues such as liquor violations,

2508-524: The air domes allowed patrons to view motion pictures in a venue that was cooler than the stifling atmosphere of the storefront theatre. In 1905, the nickelodeon was born. Rather than exhibiting one program a night, the nickelodeon offered continuous motion picture entertainment for five cents. They were widely popular. By 1910, nickelodeons grossed $ 91 million in the United States. The nickelodeons were like simple storefront theatres, but differed in

2584-415: The budgets of many smaller theaters. In practice, though, this has not proved to be as much of a problem as was feared. Rather, with the increased use of automated long-play systems in cinemas, the greater strength of polyester has been a significant advantage in lessening the risk of a film performance being interrupted by a film break. Despite its self-oxidizing hazards, nitrate is still regarded highly as

2660-406: The chambering of the feed and takeup reels in thick metal covers with small slits to allow the film to run through them. The projector is additionally modified to accommodate several fire extinguishers with nozzles aimed at the film gate. The extinguishers automatically trigger if a piece of film near the gate starts to burn. While this triggering would likely damage or destroy a significant portion of

2736-439: The concentration of unreacted acid. In 1855, the first human-made plastic , nitrocellulose (branded Parkesine , patented in 1862), was created by Alexander Parkes from cellulose treated with nitric acid and a solvent. In 1868, American inventor John Wesley Hyatt developed a plastic material he named Celluloid , improving on Parkes' invention by plasticizing the nitrocellulose with camphor so that it could be processed into

2812-474: The continuous showings and the marketing to women and families. The movie house, in a building designed specifically for motion picture exhibition, was the last step before the movie palace. Comfort was paramount, with upholstered seating and climate controls. One of the first movie houses was Tally's Broadway Theater in Los Angeles. The movie palace was developed as the step beyond the small theaters of

2888-428: The early 20th century were lost through this accelerating, self-catalyzed disintegration or through studio warehouse fires, and many others were deliberately destroyed specifically to avoid the fire risk. Salvaging old films is a major problem for film archivists (see film preservation ). Nitrocellulose film base manufactured by Kodak can be identified by the presence of the word "nitrate" in dark letters along one edge;

2964-523: The early to mid 20th century for destroying or heavily damaging cinemas, inflicting many serious injuries and deaths, and for reducing to ashes the master negatives and original prints of tens of thousands of screen titles, turning many of them into lost films . Even when nitrate stock did not start the blaze, flames from other sources spread to large nearby film collections, producing intense and highly destructive fires. In 1914—the same year that Goodwin Film

3040-433: The favorite of hobbyists for both historical reasons and for the ease with which a professional finish can be obtained. Most automobile "touch up" paints are still made from lacquer because of its fast drying, easy application, and superior adhesion properties – regardless of the material used for the original finish. Guitars sometimes shared color codes with current automobiles. It fell out of favor for mass production use for

3116-417: The first World War , British authorities were slow to introduce grenades, with soldiers at the front improvising by filling ration tin cans with gun cotton , scrap and a basic fuse. Further research indicated the importance of washing the acidified cotton. Unwashed nitrocellulose (sometimes called pyrocellulose) may spontaneously ignite and explode at room temperature , as the evaporation of water results in

3192-462: The frame area. However, ultrasonic splicing in the frame line area can be invisible. Also, polyester film is so strong, it will not break under tension and may cause serious damage to expensive camera or projector mechanisms in the event of a film jam, whereas triacetate film breaks easily, reducing the risk of damage. Many were opposed to the use of polyester for release prints for this reason, and because ultrasonic splicers are very expensive, beyond

3268-419: The highest-grossing first-run films for which they were no longer viable exhibition venues. They became second-run theaters or specialized in showing art house films . By 2004, only about a quarter of U.S. movie theaters still had only one screen, and the average number of screens per theater was 6.1. Eberson specialized in the subgenre of "atmospheric" theatres. His first, of the 500 in his career,

3344-625: The landing. Collodion, a solution of nitrocellulose, is used today in topical skin applications, such as liquid skin and in the application of salicylic acid , the active ingredient in Compound W wart remover. In 1832 Henri Braconnot discovered that nitric acid, when combined with starch or wood fibers, would produce a lightweight combustible explosive material, which he named xyloïdine . A few years later in 1838, another French chemist, Théophile-Jules Pelouze (teacher of Ascanio Sobrero and Alfred Nobel ), treated paper and cardboard in

3420-419: The launch of cellulose triacetate base film by Eastman Kodak in 1948. Cellulose triacetate superseded nitrate as the film industry's mainstay base very quickly. While Kodak had discontinued some nitrate film stocks earlier, it stopped producing various nitrate roll films in 1950 and ceased production of nitrate 35 mm motion picture film in 1951. The crucial advantage cellulose triacetate had over nitrate

3496-454: The mails without the need for fire safety precautions), the early generations of safety film base had two major disadvantages relative to nitrate: it was much more expensive to manufacture, and considerably less durable in repeated projection. The cost of the safety precautions associated with the use of nitrate was significantly lower than the cost of using any of the safety bases available before 1948. These drawbacks were eventually overcome with

3572-420: The major studios and were forced to close. Many were able to stay in business by converting to operate as race or pornography theaters . The death knell for single-screen movie theaters (including movie palaces) arrived with the development of the multiplex in the 1980s and the megaplex in the 1990s. Some movie palaces were able to stay in business only by getting out of the way, at least with respect to

3648-511: The manufacture of guncotton were obtained by John Hall & Son in 1846, and industrial manufacture of the explosive began at a purpose-built factory at Marsh Works in Faversham, Kent , a year later. The manufacturing process was not properly understood and few safety measures were put in place. A serious explosion in July that killed almost two dozen workers resulted in the immediate closure of

3724-452: The meantime, George Eastman had already started production of roll-film using his own process. Nitrocellulose was used as the first flexible film base , beginning with Eastman Kodak products in August 1889. Camphor is used as a plasticizer for nitrocellulose film, often called nitrate film. Goodwin's patent was sold to Ansco , which successfully sued Eastman Kodak for infringement of

3800-455: The migration of flames beyond the projection areas. A training film for projectionists included footage of a controlled ignition of a reel of nitrate film, which continued to burn even when fully submerged in water. Once burning, it is extremely difficult to extinguish. Unlike most other flammable materials, nitrocellulose does not need a source of air to continue burning, since it contains sufficient oxygen within its molecular structure to sustain

3876-407: The nickelodeons by the early 1910s the upperclass continued to attend stage theater performances such as opera and big-time vaudeville. However, as more sophisticated, complex, and longer films featuring prominent stage actors were developed, the upperclass desires to attend the movies began to increase and a demand for higher class theaters began to develop. Nickelodeons could not meet this demand as

3952-470: The outer shell would explode upon impact. An owner of a billiard saloon in Colorado wrote to Hyatt about the explosive tendencies, saying that he did not mind very much personally but for the fact that every man in his saloon immediately pulled a gun at the sound. The process used by Hyatt to manufacture the billiard balls, patented in 1881, involved placing the mass of nitrocellulose in a rubber bag, which

4028-399: The patent and was awarded $ 5,000,000 in 1914 to Goodwin Film. Disastrous fires related to celluloid or "nitrate film" became regular occurrences in the motion picture industry throughout the silent era and for many years after the arrival of sound film . Projector fires and spontaneous combustion of nitrate footage stored in studio vaults and in other structures were often blamed during

4104-530: The plant. Guncotton manufacture ceased for over 15 years until a safer procedure could be developed. The British chemist Frederick Augustus Abel developed the first safe process for guncotton manufacture, which he patented in 1865. The washing and drying times of the nitrocellulose were both extended to 48 hours and repeated eight times over. The acid mixture was changed to two parts sulfuric acid to one part nitric. Nitration can be controlled by adjusting acid concentrations and reaction temperature. Nitrocellulose

4180-408: The population from the cities, where all the movie palaces had been built, into the suburbs. The closing of most movie palaces occurred after United States v. Paramount Pictures, Inc. in 1948, which ordered all of the major film studios to sell their theaters. Most of the newly independent theaters could not continue to operate on the low admissions sales of the time without the financial support of

4256-544: The projector's components, it would contain a fire and prevent far greater damage. Projection rooms may also be required to have automatic metal covers for the projection windows, preventing the spread of fire to the auditorium . Today, the Dryden Theatre at the George Eastman Museum is one of a few theaters in the world that is capable of safely projecting nitrate films and regularly screens them to

4332-608: The public. The BFI Southbank in London is the only cinema in the United Kingdom licensed to show Nitrate Film. The use of nitrate film and its fiery potential were certainly not issues limited to the realm of motion pictures or to commercial still photography. The film was also used for many years in medicine, where its hazardous nature was most acute, especially in its application to X-ray photography. In 1929, several tons of stored X-ray film were ignited by steam from

4408-459: The same way. Jean-Baptiste Dumas obtained a similar material, which he called nitramidine . Around 1846 Christian Friedrich Schönbein , a German-Swiss chemist, discovered a more practical formulation. As he was working in the kitchen of his home in Basel , he spilled a mixture of nitric acid (HNO 3 ) and sulfuric acid (H 2 SO 4 ) on the kitchen table. He reached for the nearest cloth,

4484-446: The stock is more transparent than replacement stocks, and older films used denser silver in the emulsion. The combination results in a notably more luminous image with a high contrast ratio. The solubility of nitrocellulose was the basis for the first " artificial silk " by Georges Audemars in 1855, which he called " Rayon ". . However, Hilaire de Chardonnet was the first to patent a nitrocellulose fiber marketed as "artificial silk" at

4560-410: The upperclass feared the moral repercussions of intermingling between women and children with immigrants. There were also real concerns over the physical safety of the nickelodeon theaters themselves as they were often cramped with little ventilation and the nitrate film stock used at the time was extremely flammable. The demand for an upscale film theater, suitable to exhibit films to the upperclass,

4636-416: The use of which revolutionized photography in the 1860s. In the 20th century it was adapted to automobile lacquer and adhesives . The process uses a mixture of nitric acid and sulfuric acid to convert cellulose into nitrocellulose. The quality of the cellulose is important. Hemicellulose , lignin , pentosans , and mineral salts give inferior nitrocelluloses. In precise chemical terms, nitrocellulose

4712-489: The word only in clear letters on a dark background indicates derivation from a nitrate base original negative or projection print, but the film in hand itself may be a later print or copy negative, made on safety film. Acetate film manufactured during the era when nitrate films were still in use was marked "Safety" or "Safety Film" along one edge in dark letters. 8 , 9.5 , and 16 mm film stocks, intended for amateur and other nontheatrical use, were never manufactured with

4788-708: Was awarded $ 5,000,000 from Kodak for patent infringement—nitrate film fires incinerated a significant portion of the United States' early cinematic history. In that year alone, five very destructive fires occurred at four major studios and a film-processing plant. Millions of feet of film burned on March 19 at the Eclair Moving Picture Company in Fort Lee, New Jersey . Later that same month, many more reels and film cans of negatives and prints also burned at Edison Studios in New York City, in

4864-683: Was blamed for the Dromcolliher cinema tragedy in County Limerick in which 48 people died. Then in 1929 at the Glen Cinema in Paisley, Scotland , a film-related fire killed 69 children. Today, nitrate film projection is rare and normally highly regulated and requires extensive precautions, including extra health-and-safety training for projectionists. A special projector certified to run nitrate films has many modifications, among them

4940-408: Was discontinued for motion-picture films in favour of cellulose acetate film , more commonly known as "safety film". Nitrocellulose was found to gradually decompose, releasing nitric acid and further catalyzing the decomposition (eventually into a flammable powder). Decades later, storage at low temperatures was discovered as a means of delaying these reactions indefinitely. Many films produced during

5016-679: Was first met when the Regent Theater, designed by Thomas Lamb , was opened in February 1913, becoming the first ever movie palace. However the theater's location in Harlem prompted many to suggest that the theater be moved to Broadway alongside the stage theaters. These desires were satisfied when Lamb built the Strand Theatre on Broadway, which was opened in 1914 by Mitchel H. Mark at the cost of one million dollars. This opening

5092-403: Was formal and ornate. They were not designed for motion pictures, but rather live stage performances. In 1902, the storefront theatre was born at Thomas Lincoln Tally 's Electric Theatre in Los Angeles. These soon spread throughout the country as empty storefronts were equipped with chairs, a Vitascope projector, a muslin sheet on which the motion picture was exhibited, darkened windows, and

5168-401: Was initially based on the more traditional, "hardtop" form patterned on opera houses , but was no less ornate. His theaters evolved from relatively restrained neo-classic designs in the 1910s to those with elaborate baroque and Asian motifs in the late 1920s. The movie palace's signature look was one of extravagant ornamentation. The theaters were often designed with an eclectic exoticism where

5244-615: Was invented by French chemist Paul Vieille in 1884. Jules Verne viewed the development of guncotton with optimism. He referred to the substance several times in his novels. His adventurers carried firearms employing this substance. In his From the Earth to the Moon , guncotton was used to launch a projectile into space. Because of their fluffy and nearly white appearance, nitrocellulose products are often referred to as cottons, e.g. lacquer cotton, celluloid cotton, and gun cotton. Guncotton

5320-441: Was originally made from cotton (as the source of cellulose) but contemporary methods use highly processed cellulose from wood pulp . While guncotton is dangerous to store, the hazards it presents can be minimized by storing it dampened with various liquids, such as alcohol. For this reason, accounts of guncotton usage dating from the early 20th century refer to "wet guncotton." The power of guncotton made it suitable for blasting. As

5396-425: Was that it was no more of a fire risk than paper (the stock is often referred to as "non-flam": this is true—but it is combustible, just not in as volatile or as dangerous a way as nitrate), while it almost matched the cost and durability of nitrate. It remained in almost exclusive use in all film gauges until the 1980s, when polyester / PET film began to supersede it for intermediate and release printing. Polyester

5472-516: Was the 1923 Majestic in Houston, Texas . The atmospherics usually conveyed the impression of sitting in an outdoor courtyard, surrounded by highly ornamented asymmetrical facades and exotic flora and fauna, underneath a dark blue canopy; when the lights went out, a specially designed projector, the Brenograph, was used to project clouds, and special celestial effects on the ceiling. Lamb's style

5548-484: Was the first example of a success in drawing the upper middle class to the movies and it spurred others to follow suit. As their name implies movie palaces were advertised to, "make the average citizen feel like royalty." To accomplish this these theaters were outfitted with a plethora of amenities such as larger sitting areas, air conditioning, and even childcare services. Between 1914 and 1922 over 4,000 movie palaces were opened. Notable pioneers of movies palaces include

5624-438: Was then placed in a cylinder of liquid and heated. Pressure was applied to the liquid in the cylinder, which resulted in a uniform compression on the nitrocellulose mass, compressing it into a uniform sphere as the heat vaporized the solvents. The ball was then cooled and turned to make a uniform sphere. In light of the explosive results, this process was called the "Hyatt gun method". An overheated container of dry nitrocellulose

5700-555: Was then slowly dried at a temperature below 40 °C (104 °F). Schönbein collaborated with the Frankfurt professor Rudolf Christian Böttger , who had discovered the process independently in the same year.
