Recipe Source: Clint in cutscene after collecting 1+ Copper Ore
Ingredients: Stone.png Stone (25)Copper Ore.png Copper Ore (20)

The Furnace smelts Ore into Bars, to be used in several Crafting recipes. Clint gives you the blueprint for the Furnace in a cutscene the morning after you collect at least 1 Copper Ore. Copper ore obtained from geodes, fishing treasure, or purchased from Clint may activate the cutscene, but must be picked up as a single item from the ground to count. You can purchase a single copper ore from Clint on day 1, drop it on the ground, pick it up, and the cutscene will activate the next morning. You must exit your house between 6am and 11:30am to trigger the cutscene.

If you have not yet met Clint when he comes to give you the blueprint, the meeting will count as an introduction.

A furnace is the reward for completing the Bundle Orange.png Blacksmith's Bundle in the Boiler Room.

The furnace will occasionally make the same sound as placing down wallpaper or flooring


To smelt any ore, equip it and activate the furnace while there is Coal in your inventory. One unit of Coal is required for each smelting operation, regardless of the material or duration.

Furnaces outside the farm

It is possible to place chests and other crafted items outside the farm. Chests are useful for storing gifts close to the homes of Villagers who prefer them or to allow additional storage when Mining, Fishing, or Foraging. Worm Bins can be placed near fishing spots, Furnaces can be placed at the entrance to The Mines, or entire sections of the Valley may be utilized for Keg or Preserves Jar processing.

If a villager walks through the square where a crafted item was placed, the item will be destroyed. Below are player-created maps to indicate which tiles on the map are safe from villager-pathing.


  • 1.0: Introduced.
  • 1.3: Added ability to smelt Fire Quartz.
