For background, green-sand casting involves molds formed with silica (or chromite, or zircon) sand mixed with water and bonding compounds, notably bentonite (clay) and carbon. Finished castings ultimately leave their molds but the bonded sand remains, and what to do with that sand is one of those challenges that green-sand casters routinely discuss. Reportedly, the U.S. foundry industry ...
