Metal shop for sand blasting

A common fallacy, there. Lots of things are used for sandblasting, but
sand isn't one of them. Most common is aluminum oxide, the same stuff of
which sandpaper is made.

Nonsense. Sand may be obsolete for fancy or specialty work, but is still
commonly used for rough cleanup, like of old cast iron.

All right then. I've never heard of anyone using it in a blast cabinet,
and the instructions that came with my cabinet said not to use it.
Aluminum oxide is dry and clean and a hell of a lot stronger than
silicon sand, and comes in various grits.
