Basalt

Basalt is a mineral that can be found in the Magma Geode and the Omni Geode. It is also used in Fish Pond quests, where a Lava Eel may request one Basalt to increase the pond's capacity from 3 to 5.

Basalt can be placed in the spool of the Sewing Machine with Cloth in the feed to create clothing, and it acts as a gray dye when used with a dyeable clothing item in the feed.
