I've been Googling all morning, but can't seem to find a good guide to
abrasive blast media. Does anyone know of a good resource?

For example, over at Eastwood they have a lot of different abrasives
to use when blasting

But I'm not sure which to use and when.

Thanks,

Basically hardness of the media equates to agressivnessness of the blasting.

and size of the granule. i get different effects on my glass depending upon
size and hardness of blasting material, and air pressure.

Go to
http://www.tptools.com/

and search on "grit". You'll get a brief description of what each
of the various media are used for.

Aluminium oxide is nice and as long as it's used at a lower psi you can
re-use it dozens of times. The blast shop I worked for only used three
different "sands" Aluminium oxide, Glass bead and walnut shell for "cast
parts" and to clean without a profile.
