The Metal Melter melts ingots, lumps, blocks and tool components. It melts metals using the heat from Lava.
The Metal Caster casts molten metals into a component specified by a cast. You can create casts by placing Gold in the molten metal tank and placing an ingot, lump or tool component in the item slot. Metal Caster also requires water to operate.
You can use Florbs or the buckets from
[buckets] mod included in
fluid_lib. Florbs can transfer smaller amounts than a bucket can.
