For Your Blast Abrasive Needs

Black Max Copper Slag

**NOTICE: We no longer market or sell Blackblast coal slag due to impending CCR (Coal Combustion Residue) legislation. The EPA is mandated to rule on coal slag later this year as a CCR, and, in our opinion, the likely outcome will be that spent coal slag will be labeled as Hazardous Waste.

Based on this, we have new and better abrasives available, like SharpShot Copper Slag. Please call us at 314-241-5333 to find out more.
