Furnace

The furnace is a piece of furniture that is used to smelt some items, the most well known of them being ores, such as gold and silver. The interface is exactly the same as a Workbench. It takes absolutely no energy or fuel to run the furnace's operations. All the materials you need to craft one are 3 Torch 20 Stone and 4 Wood. When placed, furnaces give off sporadic lighting in a similar manner to that of Lava or Meteorite. The Hellforge is an upgraded furnace, allowing both regular Furnace crafting recipes and the crafting of Hellstone Bars.

You can sell a Furnace for 60 copper coins.
