Productive Metalworks Mod lets you build your own custom industrial furnace. This multi-block structure, called the Foundry, is perfect for smelting huge amounts of ore at once. It works much faster and uses less fuel compared to a regular furnace. After melting, you can pour the liquid metal into casts to make ingots, blocks, and other metal parts.
