Spider Iron: Alloy of copper and iron: ancient alchemists used to think it was one of the steps to synthesize gold. requires one copper and one iron
Meteoric Iron: I got this from the bronze mod. Stronger than normal iron (whose strength has been reduced). requires one iron and one nickel.
Rubber: A Rather weak 'metal'. made from one rubber tree log and one charcoal, which will produce 3 bars of rubber. Adding the 'bone reed' plant to the reaction will produce 3 bars of a slightly better rubber.
Cuppronickel, AKA white copper: requires 3 copper and one nickel. this alloy used to be used before the introduction of bronze.
Yellow Brass: 1 zinc, 2 copper
White brass: 2 zinc, 1 copper
Red brass: 1 zinc, 2 tin, 6 copper
Bronze: 2 copper, 1 tin. The weakest of the bronzes
Tin Bronze: 1 copper, 1 tin, stronger than normal bronze.
Aluminum Bronze: 1 aluminum, 2 copper. The strongest bronze, as strong as meteoric iron.
Kansa, AKA 'bell metal': 3 copper, 1 tin. The weakest of the bronzes.
Manganese: Useful for making manganese billon, besides that, not much.
Manganese Billon: 1 manganese, 4 silver, 5 copper. Slightly less valuable than normal billon.
Refined Uristlam: a semi-magical metal that is useful in the production of heat-resistant alloys. It comes in strand form, so it takes 3 times the normal amount to make an object.
Blue lead: I like to make my sarcophagi out of lead and pewter. Personal preference, I guess. But currently those materials don't make very expensive resting places, so I added this as a more expensive alternative. requires 1 voidstone, 3 lead bars, and 3 uristlam wafers, yielding a total of 4 blue lead bars. (3 wafers=1 bar's worth of material)
False galvorn: looks like galvorn, kinda. valuble, but not nearly as valuble or useful as the other forms of galvorn. requires 1 voidstone, 6 uristlam wafers, and 1 silver bar, yielding 3 false galvorn bars.
Zagithosod: Produced by the refinement of fossilized demon bones. Some of the vile essence of the previous owners of the bones still lingers on in the bones, making it useful in the production of several 'evil' metals.
Chromite: useful for making stainless steel and for making really shiny statues.
Stainless steel: The weakest steel, it will probably be more useful once corrosion has been added. requires 3 nickel bars, 3 chromite bars, 3 iron bars, 3 pig iron, 3 flux stones, and 3 coal yields 10 bars, instead of 12 because of a typo.
Shadowsteel: The second most powerful steel alloy. requires 1 iron, 1 pig iron, 1 flux, 1 coal, and 1 zagithosod, producing 3 bars.
Dwarven Steel: The most powerful tradeable steel, requires 1 iron, 1 pig iron, 1 flux, 1 coal, 3 uristlam wafers, and 1 refined voidstone bar,m producing 3 bars of dwarven steel.
Umbral brass: 'Evil' orchalcum, requires 2 copper, 2 zinc, 3 mithril wafers, 2 voidstone, and 1 zagithosod. Produces 6 bars. Very strong.
Shedimral: mithril tainted by the addition of zagithosod. Requires 3 mithril wafers, 2 voidstone, and 1 zagithosod. Yields 6 wafers.
Purple Gold: 3 gold, 1 aluminum.
White Gold: 3 gold, 1 nickel
Green Gold: 3 gold, 1 silver
Tumbaga: 1 gold, 3 copper
Galvorn (spoilers!!): 3 voidstone, 6 adamantine wafers, 3 mithril wafers, 1 coal produce 2 galvorn bars and one dross galvorn bar. Stronger than adamantine.
Royal Galvorn(spoilers!!): The strongest metal in the game. Quite difficult to make. Requires 2 voidstone, 6 adamantine wafers, 1 coal, and one osmium bar.
Osmium (spoilers!!): onnly obtainable by melting down the masterwork osmium statues that are dropped by ancient golemns, a form of HFS.
Dross galvorn(spoilers): weakest galvorn alloy (stronger than false galvorn), a byproduct of galvorn production.
Orchalcum: made form 2 copper, 1 voidstone, 2 zinc, and 3 mithril wafers. Yields 5 orchalcum bars.
Mithril Steel: The strongest steel alloy. Requires 1 iron, 1 pig iron, 1 flux, 1 coal, 1 voidstone, and 3 mithril wafers.
Patterned steel: stronger than normal steel and stainless steel, weaker than dwarven steel. requires 1 iron, 1 pig iron, 1 flux, 1 coal, and 1 uncut green glass gem.
Gelidus: Enchanted Ice. requires 3 ice, and one voidstone, yielding 3 bars. Careful, it melts at the same temperature as Ice.
Refined Voidstone: An essential ingredient to the production of any of the magical alloys, it is refined from raw voidstone.
Fell-Iron: Made from 2 iron, 1 voidstone, and 1 zagithosod, yields 3 bars. equal to stainless steel in strength, but there are better applications for your voidstone and zagithosod.
