[Shop-talk] blast media

[Eric Russell]

IME, Black Beauty (coal slag) is cheap but dusty & dirty. I'm not sure how
long lasting it is, either.

I use Aluminum Oxide - great for rust & paint removal. Avoid using on
machined surfaces (a layer or two of duct tape can be used to prevent
harming machined surfaces).
I have also used crushed glass - made from recycled glass. The sharp edges
cut well without being too aggressive.

Do be careful if you spill any glass beads. It will be like walking on
greased ice...

TP Tools has lots of options with good descriptions of each.
