This permits the use of much finer sands with lower permeability than allowable with water sand molds. This means precise castings using only ordinary foundry equipment. In practice the standard mixture using sand with a GFN of 90 has a permeability of only 15. Nevertheless, this is adequate for non-ferrous alloys because of much lower gas evolution.
