Billiard ball Billiard ball A billiard ball is a small, hard ball used in cue sports, such as carom billiards, pool, and snooker. The number, type, diameter, color, and pattern of the balls differ depending upon the specific game being played.

Although affordable ox-bone balls were in common use in Europe, elephant ivory was favored since at least 1627 until the early 20th century; the earliest
Phenol formaldehyde resin for making exterior plywood commonly known as WBP (Weather & boil proof) Plywood because phenolic resins have no melting point but only a decomposing point in the temperature zone of and above. Phenolic resin is used as a binder in loudspeaker driver suspension components which are made of cloth. Billiard balls are made from solid Phenolic resin. Sometimes people select phenolic resin parts because their coefficient of thermal expansion closely matches that of the aluminium used for other parts of a system, as in early computer systems and Duramold. The Dutch forger Han van Meegeren mixed phenol formaldehyde with his
