The recipe is similar to the normal furnace crafting recipe but uses Dwarven bricks instead of cobblestone. The forge can be crafted on the Dwarven or Blue Mountains crafting table. They also emit smoke particles through the hole in their top.

In the renewed version only, forge recipes can be configured using datapacks, and they smelt at half the speed of their 1.7.10 equivalents. Therefore, by looting one from a mine, evil-aligned players may also have access to the forge because it does not have any alignment requirement. Players with positive alignment may craft a forge on a Dwarven or Blue Mountains crafting table, but they are also found in the entrances of Dwarven mines and in most other dwarven buildings. However, onlyВ oresВ and stone-based materials can be smelted in the Dwarven forge - it cannot cook food or smelt wood into charcoal, but there are no restrictions regarding fuel. It can smelt up to four items at once it can be used to make unique alloys and it is also the only way of smelting Mithril, since this metal cannot be processed in a normal furnace or any other type of forge. The Dwarven forge is a furnace-type block which has many useful properties.
