Fire Quartz is a Mineral. It can be foraged in the Mines (floors 80+) or found inside a Magma Geode or Omni Geode. It can also be found by panning or inside Fishing Treasure Chests. It may occasionally be found in a Garbage Can after the player reaches the bottom of the mines.

Fire Quartz can be destroyed by bombs.

Fire Quartz can be used along with 1 coal in a furnace to produce 3 Refined Quartz, taking 1.5 in-game hours to smelt.
