- "For generations, luckless laborers toiled in the grim planet's mines, breaking up kesselstone to extract spice and coaxium."
- ―The Galactic Explorer's Guide
The walls of the spice mines were covered in kesselstone powder.
Kesselstone was a mineral that was mined in the spice mines of Kessel to retrieve Kessel spice. Chunks of kesselstone could be ground into powder, which was then used by criminals to create a powerful narcotic. While mining for it, Kessoline, a toxic fossil fuel, was released into Kessel's atmosphere.[2]
