With the development of billiards, it is found that if the front end of the cue does not hit the center of the cue ball, it is difficult for the cue ball to move forward. In order to make the cue ball move forward without hitting the center,1At the beginning of the 9th century, Jon Carr, an Englishman, invented the world's first cannonball powder, and it was this invention that the cue ball was blocked and the earliest cannonball was produced. It is precisely because of Qiao Fen's invention that billiards have undergone earth-shaking changes. You may not have thought that Qiaofen was invented after the birth of 10, the world's first leather head. In other words, the history of shell powder is longer than the skin.
1890 or so, American WM cooperation. A. SPINKS and JACOB SCHAEFER, the top billiards players at that time, were born with the first solid joffin. That is, the shell powder we use now. The ingredients of this shell powder include lime powder, abrasive and other additives. Abrasive is the most representative one.
In 1897, WM. A.SPINKS applied for a patent and invented SPINKS CHEAK.
The important raw materials of shell powder are calcium carbonate (lime) and abrasive. The main function of abrasive is to rub the skin and make the powder effect better.
