Nitrocellulose lacquers have been used as a finish on furniture and musical instruments. The cover of the 1971 Genesis album Nursery Cryme shows Cynthia, a character in the song "Musical Box" holding a croquet mallet with a few heads on the playing field including another character of the song Henry's head that she removed with said mallet. Shots are divided into eight "disciplines", including trick/fancy, prop/novelty/special arts, and disciplines for extremes in each of the core cueing techniques. The amount of this deflection of an object ball from its expected path is increased by several things, including by dirty or pitted balls that briefly grip each other more, by a thick cut-shot angle that provides for extended friction between the balls (cut-induced throw), by slow ball-contact speed (speed-induced throw) for the same reason, by stun shots for the same reason, and by the object ball being impacted by a ball that is rapidly side-spinning (spin- or english-induced throw), which causes the object ball to roll in a curve more toward that throw direction. Straight pool is played to a specific number of points agreed on prior to the match's start, with each pocketed ball being worth one point to the shooter.
Because the game is played to a number of points normally far in excess of the fifteen points total available in the initial rack (in tournament play, one-hundred fifty points), multiple intragame racks are necessary. In nine-ball games where a handicap is given by one player being spotted a ball, some tournament venues enforce a rule that the spotted ball must be racked as one of the two balls in the row directly behind the 1 ball. Snooker is played on a large table (full, pro tournament size is 12 × 6 ft). It has no number and no markings at all, therefore its easily distinguishable from the other balls on the table. A number of rules have developed which detail what must be done when one or both of the cue ball and fifteenth object ball are either in the rack area at the time an intragame rack is necessary, or are in such close proximity to the intragame racking area, that the physical rack cannot be used without moving the one or the other. It fell out of favor for mass production use for a number of reasons including environmental regulation and the cost of application vs.
In the form of collodion it was also a critical component in an early photographic emulsion, the use of which revolutionized photography in the 1860s. In the 20th century it was adapted to automobile lacquer and adhesives. Nitrocellulose lacquer is spin-coated onto aluminium or glass discs, then a groove is cut with a lathe, to make one-off phonograph records, used as masters for pressing or for play in dance clubs. Guncotton, dissolved at about 25% in acetone, forms a lacquer used in preliminary stages of wood finishing to develop a hard finish with a deep lustre. 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. Collodion, a solution of nitrocellulose, is used today in topical skin applications, such as liquid skin and in the application of salicylic acid, the active ingredient in Compound W wart remover. The balls used are smaller and the table is pocketed.
At that time, the fourteen pocketed balls are racked with no apex ball, and the rack is so placed so that if the apex ball were in the rack, its center would rest directly over the table's foot spot. In the initial rack in straight pool, fifteen balls are racked in a triangular rack, with the center of the apex ball placed over the foot spot. 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. In both one-pocket and bank pool all fifteen object balls are racked entirely at random, with the center of the apex ball placed directly over the foot spot. The apex must be as close as possible to the pink ball without touching it. The first ball must be placed at the apex position (front of the rack and so the center of that ball is directly over the table's foot spot). In April 2013, Reg Bamford of South Africa beat Ahmed Nasr of Egypt in the final of the Golf Croquet World Championship in Cairo, becoming the first person to simultaneously hold the title in both association croquet and golf croquet.
