—Information accurate as of: build 25211
The Furnace is a craftable item that can be used to smelt metals.
The Furnace can be used after it has been crafted and placed. To place the Furnace you must first craft it and move it to your Hotbar, from here you can move it around until the "Ghost Furnace" has turned Blue (Indicating it can be placed) Once the Furnace has been placed it can be operated by a player (Any number of players can operate it at the same time) and shows an empty 1x6 grid.
To use the Furnace a player must place Wood in it and ignite it.The furnace will burn up to two Wood and create the smelted version of the materials every 30 seconds. Players do not have to be near the Furnace for it to operate, and it will keep burning until it is turned off, runs out of fuel or if any item slot is filled and it cant find space for either the smelted material or charcoal. A byproduct of the process is Charcoal, which you need to make Gunpowder. Furnaces will smelt all slots simultaneously, so it is more efficient to smelt multiple stacks of the same ore at one time.
The Furnace can be crafted with:
- 50 low grade fuel
- 100 wood
- 200 stones
The Furnace can be repaired with a Hammer:
- 27 low grade fuel
- 50 wood
- 98 stones
The Furnace can be repaired with a Repair Bench:
- 25 low grade fuel
- 50 wood
- 100 stones
