The solubility of nitrocellulose was the basis for the first "artificial silk" by Georges Audemars in 1855, which he called "Rayon". Because of this predicament, production ceased early in the 1900s. Nitrocellulose was briefly known as "mother-in-law silk". By the late 1990s, polyester had almost entirely superseded triacetate for the production of intermediate elements and release prints. 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. Many were opposed to the use of polyester for release prints for this reason, and because ultrasonic splicers are very expensive, beyond the budgets of many smaller theaters. For this reason, immersing burning film in water may not extinguish it, and could actually increase the amount of smoke produced. 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. In his From the Earth to the Moon, guncotton was used to launch a projectile into space. Guncotton was originally made from cotton (as the source of cellulose) but contemporary methods use highly processed cellulose from wood pulp.

The power of guncotton made it suitable for blasting. Along with English, you may have heard the term "squirt," "left English," or "right English." Well, if you’re confused by English, don’t worry. Unwashed nitrocellulose (sometimes called pyrocellulose) may spontaneously ignite and explode at room temperature, as the evaporation of water results in the concentration of unreacted acid. It is common knowledge what immense results have followed the introduction, some twenty years ago, of the Four Three-quarter System. The same applies if you have cleared the table but pocket both the cue ball and the 8-ball during the final shot.

Additionally, the rules and scoring systems differ between snooker and billiards. In the game of snooker, scoring is an essential aspect that adds excitement and challenge to the gameplay.

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.
