You demanded it, so they made it. The popular Lava performance chalk is now available in traditional blue. If you're not familiar with Lava chalk, here's the scoop:

Lava rocks are created from lava that flows at crazy high temperatures
These temperatures create viscosity
Viscosity equals friction
Friction is what keeps chalk on your tip (and as a result, reduces miscues)

The blue color is perfect for green or blue cloth. If you have red or burgundy cloth, check out the original rust colored Lava chalk.
