Garnet
Garnet is a natural mineral abrasive which is irregularly shaped with polished edges, it contains no heavy materials and has a low level of free silica. Because garnet is very heavy and hard for a mineral abrasive it accomplishes a fast cleaning rate. It is being used to remove rust, mill scale, old coatings and to clean buildings. Some of the advantages of garnet are; fast cleaning, relatively low dust generation (as compared to copper- or coal slag), environmental friendly and reusability.
