Official artistic pool competitions often feature equipment limitations, such as playing with a single cue or all shots not being allowed to leave the bed of the table. The alternative is the cheaper MDF (wood) bed pool table. The biggest complaint about using pool table shims in a garage is how it looks. In the meantime, George Eastman had already started production of roll-film using his own process. 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 the frame area. Polyester is much more resistant to polymer degradation than either nitrate or triacetate. By the late 1990s, polyester had almost entirely superseded triacetate for the production of intermediate elements and release prints. 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.
Then a second fire hit the Edison Company at another location on December 9, at its film-processing complex in West Orange, New Jersey. Millions of feet of film burned on March 19 at the Eclair Moving Picture Company in Fort Lee, New Jersey. 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 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. 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.
In that year alone, five very destructive fires occurred at four major studios and a film-processing plant. Salvaging old films is a major problem for film archivists (see film preservation). This is mostly a problem in the winter, but it’s an easy fix. No, it’s better for everyone if I avoid the break. 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. PET, like cellulose mononitrate, is less prone to stretching than other available plastics. If the table has any leather on it (like the pockets), dry weather and extreme temperatures can cause it to dry out. 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. Even after film technology changed, archives of older films remained vulnerable; the 1965 MGM vault fire burned many films that were decades old. Billiard balls are pretty tough, but even a small chip can change the ball’s dynamic on the table.
The most common fix for this is to place the table widthwise if you have the room. If Native Americans attacked, the family would need a place to hide, so Brown's design included nine secret passageways and a hidden room adjacent to the Indian Lookout room. 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 a flame. Once burning, it is extremely difficult to extinguish. 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. The café takes its name from Google's first lead chef, Charlie Ayers. This was used commercially as "celluloid", a highly flammable plastic that until the mid-20th century formed the basis for lacquers and photographic film. Many films produced during 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.
