| Recipe Source | Clint in cutscene after collecting 1+ Copper Ore |
| Ingredients |  Stone (25) 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 
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

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, and entire sections of the Valley may be utilized for Keg or Preserves Jar processing. Common Trees can be planted in tillable soil and tapped.
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. The tiles with the Rotten Plant should be safe.
Safe-pathing images of the interiors of homes and buildings can be found in the complete image gallery located at https://imgur.com/a/JlRXGlc
Note that items placed on the docks at the beach may be destroyed by villagers during the Dance of the Moonlight Jellies, Night Market, or by Emily if married to her. The image below is accurate for players who do not attend the festivals and don't marry Emily.
Note: These images are accurate as of v1.4; they do not include any of Leo's paths outside of The Mountain.
