Lava ChalkFormed miles beneath the earth molten core at 2000 degrees Fahrenheit, Lava Chalk's key ingredient basaltic magma takes shape. Once the magma chills into a rock called scoria, it is crushed and pulverized by the good people at Lava Chalk and crafted into the little cue chalk blocks you see today. Manufactured with no dyes or chemical, the unique rust color of Lava Chalk comes from the iron in rock it is crafted from. This means the chalk is safe for you and your cue tips! Using Lava Chalk will maximize the friction of your cue's tip and will offer you an extreme amount of cue ball control. Turn up the heat and make you competition sweat with Lava Chalk.
