Blasting with Crushed Glass Grit
The angular particles in crushed glass grit allow for aggressive surface profiling and removal of coatings such as epoxy, paint, alkyds, vinyl, polyurea, coal tar and elastomers. Glass grit is lighter weight than many slags, allowing for increased consumption efficiency and production time – up to 30-50% less glass grit used. Crushed glass grit delivers very low particle embedment, which produces a whiter, cleaner finish. Similar to many slags, crushed glass grit has a hardness of 5.0 – 6.0 on the Moh’s Hardness Scale.
Crushed Glass Grit and the Environment
Since crushed glass grit is manufactured from bottle glass, it contains no free silica which is commonly found in blasting sand. The use of post-consumer glass directly benefits the environment by diverting waste from landfills. Crushed glass grit is free of heavy metals such as arsenic, lead, asbestos, beryllium, titanium, etc., all typically found in coal and mineral slags.
*The smaller the mesh number, the coarser the grit.

Crushed Glass has been added to the Qualified Products List by the US Navy. Crushed Glass is qualified under MIL-A-2262-B, Amendment-2 - Abrasive Blasting Media Ship Hull, Blast Cleaning. Based on toxicological safety evaluations by the Naval Environmental Health Center (NEHC), Crushed Glass Grit could be safely used for its intended purpose. The addition of Crushed Glass to QPL includes Coarse (10-40 mesh) and Medium (40-70 mesh).
