- Cue chalk comes in various colors and price ranges. The color of cue chalk should generally match the color of the felt on the pool table, so any chalk left behind can be lightly dusted away without leaving noticeable residue. The most common colors are blue and green, but chalks are also available in orange, burgundy, charcoal, tan, black, red and more.
- Though the cue stick has been around since the 1600s, cue chalk is a relatively newcomer to the game of billiards. Even before cue sticks had leather tips, cue chalk was used to increase friction between the ball and wooden cues. Women were not allowed to use cue sticks but had to use maces instead.
- Modern cue chalk composed of silica and corundum was the combined invention of chemist William Hoskins and billiard professional William A. Spinks. The combination of the two substances finally gave Spinks the cue-ball action he wanted.
- Most professional pool players prefer to use tan cue chalk.
- It has been thought that cue chalk causes lead poisoning in children who ate it. Some brands and colors of chalk have been found to contain high enough levels of lead to cause legitimate concern about lead poisoning, while other brands and colors contain only trace amounts of lead.
