Forges are created by making a 1x1 hole that is surrounded by any combination of cobblestone, bricks, stone, or smooth stone on all four sides and underneath. Either 7 pieces of charcoal or a coal block are then placed with in the hole, and lit with a firestarter or a flint & steel. Using the firestarter may take multiple tries before the forge is successfully lit.
Once the forge has been lit it will quickly burn out unless more fuel is added to the GUI. In order to relight the forge, at least one piece of fuel must be placed in the fuel slots, and a firestarter or flint & steel must be used toon the forge block.
Forges must have proper ventilation in order to work. Forges can be exposed directly to the sky for ventilation, but will stop working during rain or snow. Alternatively, a chimney structure can be used to protect the forge from precipitation, while allowing it to still be properly ventilated. The following images are examples of where the air blocks must be in valid chimney structures, where the stained glass represents an air block. Note that the chimney cannot go diagonally from the forge block. Additionally, the vertical portion of the chimney's air blocks must have direct access to the sky (i.e. assume that the vertical stack of stained glass blocks goes all the way to the world's build height limit in the images). The horizontal line of stained glass can be either air blocks, or any non-opaque block such as bellows or a crucible. Alternatively, chimney blocks may be used in place of air.
Forges are used to heat up items for smithing, as well as for making torches. Forges also provide a heat source for crucibles and wrought iron grills. The forge on it's own cannot be used to cook food or to smelt ores.
Note: If the player is unable to access the GUI after the forge has been created, it is likely that the forge does not have a valid chimney.
An Iron Grill can be placed on top of a forge or firepit in order to cook large amounts of food, while also adding the Smoked decay modifier (the only way to get this applied to non-meats/cheese). The iron grill can cook 6 slots of food at a time (up to 80oz portion in each slot), and is faster in cooking food. To access the forge underneath to refuel it, crouch and to lift up the grill. There must not be any food cooking before lifting up the grill.
Note: As of 0.85.5, the Grill is deprecated, and will not work for cooking certain food. The grill will eventually be replaced.
Forges will gradually heat items in the heating slots as long as it is burning fuel. Items that reach their melting temperature will grab an empty ceramic mold from the storage slots and attempt to place the unshaped ingots in the storage slots. If there is no room in the storage slots, the unshaped ingots will be spit out into the world. If there are no ceramic ingot molds in the storage slots, the melting metal will be destroyed.
Items in a forge can only get as hot as the current burning temperature of the fuel. A bellows can be used to increase the current burning temperature at the fuel, and heat the forge twice as fast at the expense of consuming the fuel twice as fast. Note: Bellows only affects how quickly the forge itself heats up. Items heating up inside of the the forge will heat up at the same rate regardless of if a bellows is used or not.
Note: The Ceramic Blowpipe can be used as a less effective bellows.
When the forge runs out of fuel, the items in the heating slots will start to cool down, and the forge will eventually turn off.

|77.0||Forges are destroyed when removing any of the containing walls.|
|78.7||Forges can be created with a charcoal block, or a vanilla coal block.|
|78.12||Forges will have a static temperature of 2,000 in debug mode.|
|79.9||Large items that return more than one unshaped ingot worth of metal will grab a mold from the storage slots and attempt to place the unshaped ingot in the storage slots.|
|If there is no room in the storage slots, the unshaped ingots will be spit out into the world.|
- The blocks around a forge can be chiseled once the forge has been created, as long as the forge does not receive a block update afterwards.
- Forges do not take up the full 1m³ space, and therefore will be broken by falling gravity-affected blocks.
