Pyrotheum dust can be combined with books and essence of knowledge in an arcane ensorcellator to produce Smelting enchanted books.
When used as fuel in a furnace, one piece of pyrotheum dust lasts 1,200 seconds, which is enough to smelt up to 120 items. It lasts just as long as blaze rods.
When used together with 100 mB of gelid cryotheum as fuel in a reactant dynamo, pyrotheum dust yields 400,000 RF per piece, or 500,000 RF if an elemental catalyzer is installed.
