I recently invested in a blasting cabinet and some glass beads, but when the glass beads came I noticed that there was what looked like dirt in the bag. The picture quality is terrible but you can sort of get an idea of what I'm talking about
:
(in real life the specs are more obvious)
Should I do something about this? I was thinking maybe I could put them in a bucket of water and the dirt would float and separate from the glass beads.
any ideas?
