| 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 you the blueprint for the Furnace in a cutscene the morning after you collect at least 1 Copper Ore. You must exit your house between 6am and 11:30am to trigger the cutscene. (Note that you can get the Copper Ore from anywhere, including from a fishing chest or from purchasing it from Clint directly. You do not have to drop the ore on the ground 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 
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 your inventory. One unit of Coal is required for each smelting operation, regardless of the material or duration.

It is possible to place Furnaces and other crafted items outside the farm. They can be placed at the entrance of the Mines to maximize efficiency for smelting ore into bars.
