What is the shell powder used by players to wipe the leather head of the club in snooker competition?

The important raw materials of shell powder are calcium carbonate (lime), abrasive and other additives.

Chalk powder, also called smart powder, is coated on the club head to enhance the friction between the club and the cue ball. Talcum powder is usually pressed into cubic talcum powder blocks. The composition is basically the same as the chalk we usually use, but there are some differences. Chocolate powder is generally divided into two types: one is light white and green, which is used on snooker clubs; The other is blue, which is usually used on 9-ball or 16 color clubs. The difference between the two kinds of chocolate powder lies in the dry humidity, the former powder is drier; The blue chocolate in the back, that is, the chocolate used for 9-ball clubs, is wet, which is caused by the different leather heads of the two clubs.

The main function of wedge powder is to increase the friction of the leather head of the club and prevent it from slipping when hitting the ball. Generally, it is pressed into a square with special powder. Pay attention to spread the clever powder evenly, usually once every three or five times. Coating shell powder evenly on the leather head can increase the friction between the leather head and the cue ball, and prevent players from slipping because the leather head is too smooth when using the high and low pole or the play-off (side spin ball). At the same time, after coating the shell powder, the players can use the pole method more sharply and effectively.
