The patent rights for 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. 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 a photographic film. 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. The solution was named collodion and was soon used as a dressing for wounds. In 1851, Frederick Scott Archer invented the wet collodion process as a replacement for albumen in early photographic emulsions, binding light-sensitive silver halides to a glass plate. More-stable and slower-burning collodion mixtures were eventually prepared using less concentrated acids at lower temperatures for smokeless powder in firearms. As 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.


Magicians' flash paper are sheets of paper consisting of pure nitrocellulose, which burn almost instantly with a bright flash, leaving no ash or smoke. For this reason, immersing burning film in water may not extinguish it, and could actually increase the amount of smoke produced. Carom games such as straight-rail, three-cushion, balkline, and five pins make use of only three balls: a red object ball, one solid white cue ball for player one, and another cue ball that is white with a dot on it, or yellow, for player two. The order of the balls should be random, with the exceptions of the 8-ball, which must be placed in the center of the rack (i.e., the middle of the third row), and the two back corner balls, one of which must be a stripe and the other a solid. In combination with breech-loading artillery, such high explosive shells could cause greater damage than previous solid cannonballs. Even on the occasions when nitrate stock did not start a devastating blaze, once flames from other sources spread to large nearby film collections, the resulting combustion greatly intensified the fires and substantially increased the scope of their damage.


Cinema fires caused by the ignition of nitrocellulose film stock commonly occurred as well. In that year alone, five very destructive fires occurred at four major studios and a film-processing plant. Then a second fire hit the Edison Company at another location on December 9, at its film-processing complex in West Orange, New Jersey. 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. Millions of feet of film burned on March 19 at the Eclair Moving Picture Company in Fort Lee, New Jersey. Owing to public safety precautions, London Underground forbade transport of movies on its system until well past the introduction of safety film. In 1868, the first croquet all-comers meet was held at Moreton-in-Marsh, Gloucestershire, and in the same year, the All England Croquet Club was formed at Wimbledon, London. As of 2023, the Golf Croquet World Champion was Matthew Essick (USA), and the Women's Golf Croquet World Champion was Jamie Gumbrell (Australia).


Oxford University Croquet Club. Jean-Baptiste Dumas obtained a similar material, which he called nitramidine. 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. During the year 1914-the same year that Goodwin Film was awarded $5,000,000 from Kodak for patent infringement-nitrate film fires incinerated a significant portion of the United States' early cinematic history. Goodwin's patent was sold to Ansco, which successfully sued Eastman Kodak for infringement of the patent and was awarded $5,000,000 in 1914 to Goodwin 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. Later that same month, many more reels and film cans of negatives and prints also burned at Edison Studios in New York City, in the Bronx; then again, on May 13, a fire at Universal Pictures' Colonial Hall "film factory" in Manhattan consumed another extensive collection. Nitrocellulose lacquer is spin-coated onto aluminium or glass discs, then a groove is cut with a lathe, to make one-off phonograph records, used as masters for pressing or for play in dance clubs.
