Black Magic® Coal Slag

Recycled lignite coal by-product for fast abrasive blast cleaning and used in a variety of industrial and commercial applications. Manufactured by Abrasives Incorporated.



Black Magic® coal slag is a recycled by-product of lignite coal-fired power plants. Our slag is created from a hotter source which creates a harder material and conforms to environmental standards. The extensive screening process we use to size our slag results in more consistently sized particles that are less likely to clog equipment. As a result, users of Black Magic® say it cleans faster, better and has less dust than other slag products. A sharp, angular shaped blasting media, cost effective, low free silica, coal slag is a common choice by contractors for a wide variety of substrates. Made in the USA.
