Air Eraser Bead Blaster

Hello,
We need to do some glass bead blasting. We would prefer a small Air Eraser like the size of a Paasche AEC.

What ‘mesh’ and type of glass bead should we use for sterling silver to obtain a satin finish.

What is a brand and supplier of glass bead?

Has anyone used a certain brand and model of Air Eraser they like?

Has anyone used a quart media and how does it compare to glass beads?

If you have used a quartz media what grit do you use and where can it be purchased.

Sorry for all the questions but we can’t seem to find a lot of this information applicable to jewelers

Thank You…Greg Miller
