What do you need to make a furnace in Terraria?

Updated October 2026 · How we answer

Short answerTo make a furnace in Terraria, you need 20 stone blocks and a work bench. Stand near the work bench and craft the furnace from the crafting menu.

Materials and Crafting Station

A furnace requires 20 stone blocks. Stone is obtained by mining the gray blocks that make up the underground layer with any pickaxe. You'll also need a work bench, which is crafted from 10 wood.

Once you have both, stand within range of the work bench (about 3 tiles) and open your crafting menu. The furnace will appear as a craftable item under the 'Furniture' category.

  • 20 stone blocks
  • Work bench (crafted from 10 wood)
  • Stand near the work bench to craft

Uses and Placement

After crafting, place the furnace down by selecting it in your hotbar and clicking on the ground. The furnace is used to smelt ores into bars, make glass from sand, and craft various other items like torches and bricks.

You can also use the furnace to craft a Hellforge later in the game, which is needed for smelting Hellstone. The furnace itself can be picked up with a pickaxe and moved if needed.

  • Smelts ores into bars
  • Makes glass from sand
  • Crafts torches, bricks, and more
  • Can be upgraded to Hellforge

Common mistakes

  • You don't need a furnace to make a work bench; it's the other way around.
  • Stone is not the same as cobblestone; in Terraria, you mine stone blocks directly.
  • You must be near a work bench to craft the furnace, not just have the materials.
