Nitrocellulose was found to gradually decompose, releasing nitric acid and further catalyzing the decomposition (eventually into a flammable powder). 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. The object balls include seven solid-colored balls numbered 1 through 7, seven striped balls numbered 9 through 15, and the black 8 ball. From where the striker ball stopped after the roquet. If the 8 ball is pocketed on the break, then the breaker can choose either to re-spot the 8 ball and play from the current position or to re-rack and re-break; but if the cue ball is also pocketed on the break (colloquially referred to as a "scratch") then the opponent is the one who has the choice: either to re-spot the 8 ball and shoot with ball-in-hand behind the head string, accepting the current position, or to re-break or have the breaker re-break. He referred to the substance several times in his novels. 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.



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. 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. Despite its self-oxidizing hazards, nitrate is still regarded highly as the stock is more transparent than replacement stocks, and older films used denser silver in the emulsion. The use of nitrate film and the looming threat of its fiery potential were certainly not issues limited to the realm of motion pictures or to commercial still photography. 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.



A special projector certified to run nitrate films has many modifications, among them the chambering of the feed and takeup reels in thick metal covers with small slits to allow the film to run through them. 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. While this triggering would likely damage or destroy a significant portion of the projector's components, it would contain a fire and prevent far greater damage. While guncotton is dangerous to store, the hazards it presents can be minimized by storing it dampened with various liquids, such as alcohol.



In his From the Earth to the Moon, guncotton was used to launch a projectile into space. The power of guncotton made it suitable for blasting. Safe and sustained production of guncotton began at 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. Nitrocellulose lacquer manufactured by (among others) DuPont, what is billiards was the primary material for painting automobiles for many years. Slate is the most widely-used material for pool table playing surfaces. What is a Slatron Pool Table? In short, playing on a slate table just seems to make everything smoother. However, though various elements in the game of billiards have changed over the years, one thing remains the same - players need plenty of light if they’re going to make the most out of their experience.
