After two minutes, the cotton was removed and washed in cold water to set the esterification level and to remove all acid residue. Table tennis balls, guitar picks, and some photographic films have fairly low esterification levels and burn comparatively slowly with some charred residue. At one end of the table (the "baulk end" ) is the so-called baulk line, which is 29 inches from the baulk end cushion. Finally, the black ball is placed on a spot 12.75 inches from the top cushion on a full-size table. What Is the Average Size of a Billiard Table? Snooker is played on a large table (full, pro tournament size is 12 × 6 ft). In short, playing on a slate table just seems to make everything smoother. The Dazzler isn’t just playing against Roberto Gomez - he is playing against a whole nation! It is used to coat playing cards and to bind staples together in office staplers. Re-felting might be needed from time to time, but the slate itself is virtually indestructible under normal playing conditions. Indeed, as one fan shouted, "IT IS SHOW TIME!" Roberto Gomez is showing nerves of steel now! Coloured ball racking positions must be remembered with care, as each time a coloured ball is potted, it is immediately replaced to its starting position, which occurs multiple times per frame, whereas reds are not returned to the table's surface after being potted.

An easy way to remember these positions is with the mnemonic, 'God Bless You', with the first letter of each word being the first letter of the three colours as they are racked from left to right on the baulk line. Studies have shown that these gentle colors - the classic pool table green and Tournament Blue shades specifically - are very easy on the human eye. As he was working in the kitchen of his home in Basel, he spilled a mixture of nitric acid (HNO3) and sulfuric acid (H2SO4) on the kitchen table. The process uses a mixture of nitric acid and sulfuric acid to convert cellulose into nitrocellulose. Nitrocellulose (also known as cellulose nitrate, flash paper, flash cotton, guncotton, pyroxylin and flash string, depending on form) is a highly flammable compound formed by nitrating cellulose through exposure to a mixture of nitric acid and sulfuric acid. Thus, nitrocellulose can denote mononitrocellulose, dinitrocellulose, and trinitrocellulose, or a mixture thereof. In precise chemical terms, nitrocellulose is not a nitro compound, but a nitrate ester.

The glucose repeat unit (anhydroglucose) within the cellulose chain has three OH groups, each of which can form a nitrate ester. The principal uses of cellulose nitrate is for the production of lacquers and coatings, explosives, and celluloid. The explosive applications are diverse and nitrate content is typically higher for propellant applications than for coatings. It was also used to replace gunpowder as a low-order explosive in mining and other applications. 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. However, after several missions and flights, it proved not to have the desired explosive properties in a near vacuum environment. For space flight, nitrocellulose was used by Copenhagen Suborbitals on several missions as a means of jettisoning components of the rocket/space capsule and deploying recovery systems. In terms of lacquers and coatings, nitrocellulose dissolves readily in organic solvents, which upon evaporation leave a colorless, transparent, flexible film.

Nitrocellulose lacquers have been used as a finish on furniture and musical instruments. Membrane filters made of a mesh of nitrocellulose threads with various porosities are used in laboratory procedures for particle retention and cell capture in liquid or gaseous solutions and, reversely, obtaining particle-free filtrates. The following examples are believed to be the most commonly practiced in North America, in regards to both professional and amateur play. Such rules are detailed on the following chart (note therein that the kitchen refers to the area behind the table's head string). The rules also vary depending on whether the cue ball or fifteenth ball are resting on the table's head spot. It is played using a cue stick, one white ball (the cue ball), fifteen red balls and six colours: a yellow (worth two points), green (three points), brown (four points), blue (five points), pink (six points) and black ball (seven points).
