Slag (Thermal Expansion 3)

Slag 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 triples the ore output and creates a secondary byproduct of regular slag. Slag can be smelted in a furnace to create rockwool. Rockwool can be dyed like regular wool but will not burn.
