Lava Chalk 2 Piece Box

Straight from the Earth's molten core and recently a toasty 2000 degrees Fahrenheit, the key ingredient for our chalk is literally lava. Specifically, it's a basaltic magma that ends up as a rock called scoria. We take scoria, crush it, pulverize it, and convert it from volcanic slag to a powder. At that point, we use more traditional manufacturing methods, carefully calibrating our master blend to maximize the effects of the lava for billiard chalk.

But why is lava good for the end of a pool cue? Viscosity and paramagnetism. Every rock we use is the result of lava that only flows at incredibly high temperatures. It takes these thermal extremes because of its high iron content. Once the lava transforms into rock, it reacts on a subatomic level with water, essentially gluing hydrogen bonds together, trapping moisture. The effect of this process is called paramagnetism, which creates viscosity thousands of times higher than water. Viscosity equals friction and friction is the single purpose of billiard chalk. 

What about the color? It's the iron. Basaltic lava starts out black, almost like oil, until it finally erupts. When it hits the atmosphere, it oxidizes and turns reddish brown, exactly like rust. We added a coloring agent to create the familiar blue everyone knows.
