Felt color also affects the table’s cleanliness as well as the overall mood and aesthetic of the room it’s in. If there is no room this side of the spot, it will be placed as close to the spot as possible in a straight line towards the bottom cushion, without touching another ball. If there is no available spot, it is placed as close to its own spot as possible in a direct line between that spot and the top (black end) cushion, without touching another ball. Finally, what is billiards the black ball is placed on a spot 12.75 inches from the top cushion on a full-size table. Further up the table is the pink ball, which sits midway between the blue spot and the top cushion, followed by the red balls (one each), placed in a tightly-packed triangle behind the pink. If the starting position spot for a coloured ball is covered by another ball, the ball is placed on the highest available spot. They use English to position the cue ball for the next shot. Radon tests for alpha track etches use nitrocellulose. Nitrocellulose is widely used as support in diagnostic tests where antigen-antibody binding occurs; e.g., pregnancy tests, U-albumin tests, and CRP tests.

The overarching consequence is that the nitrocellulose is soluble in organic solvents such as acetone and esters; e.g., ethyl acetate, methyl acetate, ethyl carbonate. 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. As you can probably imagine, slate tables are very heavy. Internet sellers typically offer only the cheapest accessory kits and limited cloth colors with their tables. However, for home use, when the table is more for decoration, the most popular colors tend to be grey, deep reds, and light browns. 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. One of its first major uses was as guncotton, a replacement for gunpowder as propellant in firearms.

The explosive applications are diverse and nitrate content is typically higher for propellant applications than for coatings. The principal uses of cellulose nitrate is for the production of lacquers and coatings, explosives, and celluloid. The yields are about 85%, with losses attributed to complete oxidation of the cellulose to oxalic acid. After the balls are scattered with a break shot, a player is assigned either the group of solid or striped balls once they have legally pocketed a ball from that group. 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. The rules also vary depending on whether the cue ball or fifteenth ball are resting on the table's head spot. Depending on the manufacturing process, nitrocellulose is esterified to varying degrees.

The number of balls used in pool range from one to fifteen depending on the game type. If you’re setting up a pool table in your bar, pub or even your rec room, then don’t underestimate the power of good pool table lighting. It is normally the first coat applied, then it is sanded and followed by other coatings that bond to it. It is used to coat playing cards and to bind staples together in office staplers. The solution was named collodion and was soon used as a dressing for wounds. 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. 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. It was also used to replace gunpowder as a low-order explosive in mining and other applications.
