Coal Slag Abrasive with Blastox for Lead Remediation

Coal slag is a glass matrix alumina-silicate which is produced as a by-product of coal burning power plants. As the coal burns, the residual ash (slag) becomes molten. When this slag is cooled, it vitrifies into a glassy, abrasive material, which is then crushed to produce blast media. A wide range of mesh sizes are available, with some being capable of removing very thick or elastomeric coatings.
