The magma forge is a workshop used by dwarves to turn metal bars into useful objects such as weapons, ammunition, armor, furniture, coins, trap components, metal crafts and ballista arrow heads without the need for fuel to heat the forge. For its counterpart that use fuel, see Metalsmith's forge.
To build a magma forge, you must have magma-safe materials (non-magma-safe materials will not be shown on the material list), an anvil, and a build site where at least one tile directly beneath one of its eight non-center tiles contains magma at a depth of 4/7 or greater.
Note that the anvil used to build a magma forge does need to be magma-safe—normally anvils can only be made from magma-safe materials, but strange moods can create artifact anvils which cannot be used at a magma forge (or, in the case of metals like zinc, at any forge).
Covering the opening of the magma with an impassable tile of the workshop (dark green) will prevent dwarves from getting knocked in and prevent magma creatures from crawling out, possibly barring a building destroyer with an alternate route.
While it is possible to construct a magma forge without open access to magma beneath any of its 9 squares, it will not operate (you will be unable to add tasks to the workshop). Note also that, like all workshops, the central tile must be built over solid ground, as it is required for a dwarf to stand there to use the workshop, and therefore cannot be the square used to access magma (you will be blocked from building the workshop).
Workshop labors and skills
Several different types of items can be created at a magma forge; dwarves will need the correct type of labor enabled for each. The labors used at a forge are:
- Weaponsmithing – weapons, trap components, bolts, and ballista arrowheads
- Armoring (armorer) – armor
- Metalcrafting – chains, musical instrument components, and everything in the "Other Objects" category (crafts, coins, goblets, studding, etc.), except anvils
- Blacksmithing – Anvils, blocks, and all furniture except chains.
- Trapping – Animal Traps.
- Mechanics – Mechanisms.
Cost of items
The cost of a weapon or piece of armor in metal bars can be calculated by dividing its material size by three and rounding down, with no item costing less than one metal bar. The exception to this is some types of finished goods, which are created in different multiples from a single metal bar, depending on the skill of the Metal crafter. The table on the Melt page lists the cost of common items and their yields when melted.
