The ‘hottest’ abrasive blast media right now seems to be Crushed Glass Grit. This media is sourced from recycled glass – mostly bottle (beer) glass. It is generally a mixture of clear, green and brown glass. Crushed Glass Grit has lots of great advantages:
- Clean, white-metal finish
- No free silica, heavy metals or other contaminants (like in many coal slags)
- Angular shape offers quick stripping (similar to silica in hardness)
- Cost effective use
Two issues to keep in mind when using Crushed Glass Grit: (1) Media is considered consumable and is not generally re-usable; (2) Source quality can vary dramatically – we use New Age Blast Media.
