The Smelter is a craftable Structure exclusive to the Hamlet DLC. It is found in the Science Tab, requires 6 Cut Stones, 4 Boards, and 1 Red Gem to craft, and an Alchemy Engine to prototype. Upon interacting with the Smelter, a UI will appear that is similar to that of the Crock Pot. It will only accept Iron Ore, and once 4 Ore is placed inside, it will create a bar of Alloy.
In the Shipwrecked DLC, the Smelter can be flooded.
