In about a week I will be sand blasting some pot metal parts. What is the best & safest type of sand to use. Gerald

Good question. The stuff I use scuffs up steel pretty good. I think it would make pot metal disappear.

you will need a soft media so when you are done, you still have the original part!!! i would use ground walnut shell media.

Wear a respirator when using silica playground sand.

Might try glass beads. We used this media for blasting aluminum injector pump bodies when re-building them and left a nice smooth luster to the aluminum. Once it is used and recycled through the blast cabinet for a few weeks it eventually will "break up" and will then be sharp and leave a rougher finish.

Ever heard of soda blasting? Doesnt take rust off very good doesnt pit glass.

Plain sand is a poor idea -- that's the stuff with all the free silica that requires a supplied air hood . . .

There's all kinds of stuff available. The link below is to mcmaster.com, and a table of different abrasives and their effectiveness and so on. If you then cick to their next page, they list the types and quantities. You can buy by the 40 or 50-pound pail, but most of what they have is also available in smaller 10 or 15-pounds boxes, which might be better suited to your needs.

Glass bead is good. Glass bead mixed with a aluminum oxide is a little more aggressive but useful in getting through paint. As someone pointed out the glass will shatter as it hits so the more you reuse it, the rougher the finish.

Walnut shells and corncobs are good for light blasting, as well.
