The crucial advantage cellulose triacetate had over nitrate 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. The nitrocellulose lacquer yellows and cracks over time, and custom shops will reproduce this aging to make instruments appear vintage. Nitrocellulose lacquer manufactured by (among others) DuPont, was the primary material for painting automobiles for many years. 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. Tables are usually 7-foot (2.1 m) long, and feature pockets with rounded cushion openings, like snooker tables. Professional billiards tables are often larger than pool tables. Billiards and pool are often played on a seven-foot to eight-foot table. Fouls are penalized by subtracting points from the offending player’s score. During a turn, each of the other three balls may only be croqueted once between hoop points, but by stringing together a series of roquets, croquets, and scored hoops, several points may be scored in a single turn.

Nitrocellulose film base manufactured by Kodak can be identified by the presence of the word "nitrate" in dark letters along one edge; 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, what is billiards made on safety film. Polyester is much more resistant to polymer degradation than either nitrate or triacetate. 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. A good player knows how to get cue ball shape on the next shot using stroke speed, topspin or draw, punching the cue ball with the stroke, gripping the stick harder or softer, using the cloth's natural tendencies to control the cue ball, besides cutting an easy ball a bit thinner or more thick to get cue ball shape, kicking off a rail and more.

You must be able to determine your finish and start point for using this purpose. Each color ball has a different point value assigned to it. Guitars sometimes shared color codes with current automobiles. All that being said, felt color may not necessarily have a direct impact on your game - again, it’s mostly subjective. The invention enjoyed a brief popularity, but the Hyatt balls were extremely flammable, and sometimes portions of the outer shell would explode upon impact. In light of the explosive results, this process was called the "Hyatt gun method". 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. Each one, at its time of use, proved somewhat superior to its predecessor, although they could have been better. 8, 9.5, and 16 mm film stocks, intended for amateur and other nontheatrical use, were never manufactured with 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 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.

Because of its explosive nature, not all applications of nitrocellulose were successful. Pentaerythritol tetranitrate (PETN), a related explosive. When a player commits a scratch, the opposition may place the ball wherever they want on the table in our Coolmath Games version of Billiards. If a player runs out of time, it will be a standard foul. In many pool games the penalty for a foul is ball-in-hand anywhere on the table for the opponent. It is a foul to begin a shot while any ball in play is moving or spinning. In call shot games, the shooter may choose to call "safety" instead of a ball and pocket, and then play passes to the opponent at the end of the shot. The ball was then cooled and turned to make a uniform sphere. 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. An overheated container of dry nitrocellulose is believed to be the initial cause of the 2015 Tianjin explosions. Williams, Marc; Reddy, Gunda; Quinn, Michael; Johnson, Mark S. (20 May 2015).
