| Recipe Source | Clint in cutscene after collecting 1+ Copper Ore |
| Ingredients |  Stone (25) Copper Ore (20) |
The Furnace smelts ore into bars, which are used in several crafting recipes.
Clint gives the player the blueprint for the Furnace in a cutscene the morning after collecting at least 1 Copper Ore. Exit the farmhouse between 6am and 11:30am to trigger the cutscene. The Copper Ore can come from anywhere, including from a fishing treasure chest or from purchasing it from Clint directly.
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 
Blacksmith's Bundle in the Boiler Room.
A furnace is used to change a Bouquet into a Wilted Bouquet.
The furnace will occasionally make the same sound as placing down wallpaper or flooring
Smelting
To smelt any ore (or Bouquet), equip it and activate the furnace while there is Coal in inventory. One unit of Coal is required for each smelting operation, regardless of the material or duration.
