I have found a place near me that says they will do some sandblasting for me. I just want the shine blasted off so that I can fire to a matte finish. However they haven't blasted any glass before and they use sand or glass beads. Is sand ok to use?
Also, does anybody know of any places near Surprise, AZ that will do sandblasting? Maybe someone that has experience with glass?
* Why don't you try giving them a couple of pieces for testing, samples that you haven't put a lot of effort into. Then you can fire them again to test for your matte finish. Another suggestion is for you to acid etch the surface and see whether you like that. That might get you to a matte finish that you like. The drawback of the acid etching stuff is that it isn't cheap if you're planning on doing a lot of pieces like this.
* Glass beads take forever to etch glass. Sand is okay, but depending on the grain size, you may get pitting.
* I wouldn't do sand. It will probably be too course to get the results you want.
* I'd also check out what they usually blast and recycling the medium. If its cleaning motor parts you could end up with grease or metal bits that are tooo hard to clean off. Talk to them though it could be a good connection,. If they have questions about blasting glass refer them to Tony's web site.
* I have a friend who has always used just ordinary playground sand from Home Depot and her pieces always turn out beautiful. I have yet to get my sandblaster set up....
* Regular sand is banned in blasters in Australia because of the amount of ? free silica dust. Its deadly dangerous so a very good dust extraction system is needed.
* I'm a neighbor. I sent you a PM.
* Sandblasting glass with glass beads is a no-win situation: glass bead is a smooth particle, not designed to cut, so the effect is like hitting the glass surface with thousands of tiny ball-peen hammers. It's actually possible to cause tiny surface fractures with glass bead. Brock's assessment as regards silica sand is on target. If you can get graded sand, of under 100 grit size, you could get away with using it outdoors, wearing a respirator. It should be cheap enough to be a one-use media. Definitely DON'T breathe the dust. Blasting when there is a breeze to clear the dust from where you're blasting would be a plus.
* Thanks to all of you who answered my post - so much good information on this board!
