Gilsonite as a Carbonaceous Foundry Sand Additive Gilsonite as a Carbonaceous Laboratory tests were performed to determine the effect of five commonly used carbonaceous additives on new sand mixes. The additives evaluated were seacoal, pitch, petroleum asphalt, Gilsonite of a “coarse” and “fine” grind, and blown asphalt. The tests comprised evaluating physical properties of new sand mixes […]
