-- alloying furnace
--
-- there are several kinds of alloy furnace, with varying
-- capabilities. the simplest can alloy two simple metals;
-- the most complex can alloy four high-grade metals such
-- as titanium, platinum, iridium, or levitanium.
--
-- furnace recipes follow a pattern: the number of crucibles
-- determines the input slots, the type of crucible determines
-- how hot the furnace can get, and various other components
-- (like a coolant circulator) can be added to allow the
-- creation of exotic metals.
--
-- alloy furnaces produce ingots that can later be melted down
-- again and cast into a mold to produce items of particular
-- shapes.
-- there are four kinds of crucibles: clay, aluminum, platinum,
-- and duranium. clay crucibles are made by molding clay into
-- the proper shape and then firing it in a furnace. others
-- are made by casting.
