Lava Dust

Slimepedia
Lava dust is a rare resource obtained with a pump.

''Neither a solid or a liquid, lava dust seems to be something in between, having the characteristics of both. It is believed to be a mixture of magma and slime, though this has never been proven. And despite its name, lava dust is only warm to the touch.''
