All cue sports use hard and small ones Billiard balls . Depending on the game, the weight, size, type and number will vary. The coefficient of friction, hardness and resistance of the ball are very important for advanced billiard players. At first, billiards were made of wood and then made of clay. Ivory became the preferred material for billiard ball production around the 1620s. Due to the demand for them in the 1800s, the massacre of ivory elephants was tremendous. An elephant fang can only create up to 8 balls. As the elephants became publicly extinct and alert, the billiards industry was asked to find alternative materials. In 1869, John W. Hyatt invented nitrocellulose as a constituent of billiard balls. This material, later labeled celluloid, was the first industrial plastic. However, we found that celluloid billiard balls are very unstable. Subsequently, other synthetic materials such as crystallites, bakelites and other plastic compounds were tested. Modern things are made to be resistant to chips and cracks. The most commonly used materials today are phenolic resin, clear acrylic, and polyster. There are various types of billiard balls.
First example: Carom billiards. A typical carom billiard set includes a red object, a pure white cue ball, and an enemy dotted cue. It is 61.5 mm [2 + 7/16 inches] in diameter and larger than a pool ball. Some games, such as Asian games, use additional objects like four [which literally means "4 balls"]. In a carom or caran ball game, billiard balls are played on a table with a rail, 3 cushions, ball line, and related games, and a table with a pool table with a straight or pocketless. Carom has no numbers. The red object [2 red in the game 4 ball] white is used for player 1's cue ball, and white is used for player 2's single spot cue ball. Pool balls are used to play various pool games and pocket billiards such as 8 balls, 9 balls, 1 pocket. In North America they are sometimes simply called “billiard balls” [except for carom players], and in the UK they are usually called Kelly Pools or American balls.
The most widely used balls in the world are considerably smaller than carom billiard balls, but slightly larger than British style pool balls and much larger than those for snookers. According to the specifications of WPA / BCA equipment, the weight is 5.5-6 ounces. [156-170 g], diameter 2.25 inches [5.715 cm], plus or minus 0.005 inches [0.127 mm]. The balls are numbered and colored as follows: 1-yellow, 2-blue, 3-red, 4-purple or pink in some ball sets, 5-orange, 6-green, 7-brown or burgundy or tan in some balls set, 8-black 9-yellow and white, 10-blue and white, 11-red and white, 12-purple and white or pink and white in some ball sets, 13-orange and white, 14-green and white, 15-brown , Or burgundy, and white. Some ball sets are tan and white. The cue ball is white and sometimes there may be more than one spot. Balls 1-7 are usually called solids and balls 9-15 are called stripes, but there are many other slang names for each suit of the ball. Although the 8 balls look similar, they are not considered solid. Some cue sports such as nine balls do not distinguish between striped balls and solid balls. Rather, the ball number is used to determine the order in which the balls are put into the pocket.
In some billiard games, such as 3 balls, the color and number of the balls are not important. In games such as 8-ball, straight pool, all 16 balls are used. While playing 9 balls, only object balls 1-9 [and cue ball] are used. Pool games aired on television use billiard balls to create a unique color for viewers to understand. Especially 4 balls are pink instead of dark purple, 12 balls are white with pink stripes, just 8 balls of color and black, and 7 balls and 15 balls as well instead of dark brown Use light tan. Television was the main reason why the “measles” cue ball was invented, with many spots on its surface, and the spin of the ball was apparent to the viewer. Historically, coin-operated pool tables such as those found in bars and some pool rooms use larger ["grapefruit"] or higher density ["rock", usually ceramic] cue balls. The object ball [held until the end of the game, the table is paid again for another game, so that if it is accidentally put in the pocket, the cue ball can be returned for further play Cue ball return mechanism that separates from] is rarely found in the US pool tables that use small cues instead. Because players have correctly complained that large and too large cues are not "played" correctly for decades, modern tables usually employ magnetic balls of size and weight close to regulation or regulation. English pool [ Black ball ] Pools known as British pools or black balls are played characteristically in red and yellow pools. WPA black ball and WEPF or English style Eight ball pool [Do not confuse with 8-ball or English billiard games], 15 will be used, but will be arranged in two unnumbered groups, red [or blue] and yellow, white cues, and black 8. In the case of an 8-ball, the shot is not called because there is no reliable way to know which exact one is in the pocket. They are not numbered and are not at all suitable for certain pool games such as 9 balls where order is important. They are significantly smaller than American ones, the cues are slightly smaller than the object balls, and the table pockets are tight to balance.
WPA and WEPF do not specify their size or table size, but it seems that league and tournament organizers have agreed on some guidelines in this sense. Most manufacturers for this market offer 2 inch [5.08 cm] objects and 1 + 7/8 inch [4.76 cm] cues. The yellow and red sets are sometimes referred to commercially as “casino sets”. Previously, it was used for the 8-ball championship on television that was usually held in casinos. However, they used the casino set long before watching TV, at least in 1908, as they were used in the BBC Co. Pool, the predecessor of today's 8-ball.
Another example is a snooker game. At first glance, the snooker set looks like a combination of American and English pools. In total, 22 are arranged as 15 red racks without marks, 6 colors arranged in various positions on the table, and white cues. Colored balls may be given American-style numbers with point values for amateurs and home players. They are numbered as follows: 1-yellow, 2-green, 3-brown, 4-blue, 5-pink, 6-black. Snooker balls are officially standardized with a diameter of 52.5 mm [approximately 2 + 1/15 inches] within a tolerance of ± 0.05 mm [0.002 inches]. Standard weight is not defined, but all balls in the set must be the same weight within 3 g tolerance. [7] However, some sets are actually 2 + 1/16 inch [slightly less than 52.4 mm], even those of major manufacturers. The snooker set includes balls that are significantly smaller than the regulatory size [and 10 balls instead of 15 red], can be played on a small half-size table, and allowed to be used in some amateur leagues It has been.
