Billiard ball
As a billiard ball or billiard ball is called the game of billiards object. Basically, there are game balls, which must not be touched with the cue and object balls that should not be touched with the cue. Number, color and size are different in the various disciplines.
History
The earliest balls for billiards game were made of ivory, which, however, had drawbacks. The balls wore out quickly, regrinding was necessary and so that diameter and circumference changes. In addition, the behavior of the balls was not calculable because as a natural resource ivory has density differences. Another disadvantage was the limited availability of ivory, which had the effect of high commodity prices.
1863 Michael Phelan wrote a prize of $ 10,000 for an alternative to ivory sphere. In 1869, finally found John Wesley Hyatt celluloid with a thermoplastic, which met the requirements and has been continuously improved over time.
Today billiard balls are made from highly pure phenolic resin. The market leader is the Belgian company Saluc that sells its material under the name Aramith. Modern plastic bullets have much better roll characteristics compared to ivory balls and are more resistant.
Balls at the pool table
The balls at the pool table are numbered and color- precisely defined. In addition to the white cue ball, there are 15 object balls. A pool billiard ball has a diameter of 57.2 mm and weighs 170 g
The balls with the numbers 1 to 8 are referred to as the solid and the balls 9 to 15 as the Half, as the latter are colored only half right. The following colors are associated with the numbers:
1 There are differences between normal ball sets and the TV set, where the colors for better visibility slightly different on television from the original colors. Game balls with red dots give the viewers the Effet used better.
Balls in snooker
In addition to the white cue ball in snooker, there are still 21 object balls. The balls in snooker, depending on the color, different weights. Thus, each of the 15 Red worth one point, while the other, existing only once colors match, between two and seven points. As Colored balls all non- red object balls are called in snooker. A snooker ball has a diameter of 52.5 mm and weighs between 130 and 150 g
- Red = 1 point
- Yellow = 2 points
- Green = 3 points
- Brown = 4 points
- Blue = 5 points

Balls at Carambolage
When Carambolagebillard there is in most disciplines only two match balls (one for each player and each team one ) and a red object ball. Previously, both game balls were white and provided with inconspicuous markers, but now it is mostly gone for the sake of clarity to a pawn and white to color a yellow. Carambolagekugeln are 61.5 mm larger than pool and snooker balls.
