Sandblasting Mugs

[Kottwitz-Graphics]

I have a customer that has asked if I can furnish a mask so that he can sandblast glass mugs.

The size is only 3" x 2.5", and my concern is that the logo is too small to work.

Is there a special type of mask to use? When I was asked about it, before thinking, I said not a problem, thinking about paint mask, and as we talked, I began to think about blasting mask, and how it has rubber type consistency.

Is there a special type of mask to use?

Thanks,
Mark

I do stencils for a guy who blasts mirrors. I use oracal 651, 1/2 letters are about the smallest I have done for him.

651 here too. Although I use it at double thickness. Doesn't take much to blast a glass mug.

651 oracal 1/4in cut with a Graphtec, do it all the time.

Done lot's of sandblast etch glass.

I prefer to use cheap paint mask for it.
It is a little thicker and is easier to remove especially in intricate designs.

We use a cheap handheld gravity fed blaster filled with fine aluminum oxide
Blast at about 35 psi no problem.

hope this helps

We use rubber mask for stone, etc, and then use the photo resist masks for glass, etc, and I recently sold a plotter to a guy that was in the granite business and wanted to make masks for sandblasting granite. I told them that it wouldn't cut the rubber mask, took a piece of Oracal 651, stuck it on a piece of granite and went back to the sandblaster. Holy smokes! I felt dumb for buying expensive masks now. It worked fantastic. I have a really fine grit media in there, so it wasn't super aggressive, but it cut about 1/32" down into the granite with no signs of wear on the vinyl at all.

I think I'll save the rubber mask material for rough, odd shapes things, like river rocks, etc, from now on.

Great, thanks for the info guys.

I just don't think you're going to do that with a cutter, at that size. May need to think about photo resist.
