Slag (Thermal Expansion 3)

Slag is an item added by Thermal Expansion 3. It is a byproduct of smelting ore dust with Sand in an Induction Smelter. Smelting ore blocks with Sand yields a chance to drop Rich Slag. Rich Slag can be combined with ore blocks to triple the ore output and to create a secondary byproduct of regular Slag. Slag can be smelted in a furnace to create Rockwool.
