This is my entry at ArtPrize in Grand Rapids, Michigan. Over 60 pieces of kiln-formed glass. The collection is 9" tall and 20" wide.

Re: HEPA vacuum

I don't really see the point of a HEPA for a sandblast hood. Assume you are using something like Aluminum Oxide which is considered a nuisance particle. If your booth is well sealed and you have a dust collector, there should be no problem. Since you are concerned, put it outside so the fugative emm...

Re: how to remove silicone glue?

The only way I found to successfully remove silicone from glass is to put the glass in the kiln and take it to 800.

Re: Square/Squareup Credit Card processing

I have used GoPayment (from Intuit - the QuickBooks people). Works OK but their card swipper is kind of iffy. Anyone else have experience with GoPayment?

And I would assume anyone would make sure their glass was clean before they put it in their kiln! Anyway, putting Pb-crystal into a kiln does not present an exposure issue.

Re: Kiln Venting

This issue has come up many times. Unless you are firing something other than glass, there are no combustion products of concern.

Re: using water pump with MK 100--or just a hose?

I've used a Harbor Freight tile saw ($199 on sale) for years with a $10 pump I also got at HF. Works great! I also use their diamond blade ($30) which also works great. So for $240 I've got a glass saw system that I am very pleased with.

Re: Should I be short of breath using while using respirator?

Couple of questions here: 1) Should I be breathless when wearing a respirator? Depends on a few things. First of all, all negative pressure respirators depend up your lungs pulling air through a filter which provides resistance, so breathing will be a little more difficult. There are two types: filt...

ALuminum Oxide is nuisance dust - not a big concern. Blast away but keep an eye on fugative emissions (aka - leaks).

What is the grit you are using? I'm assuming you are using aluminum oxide or silicon carbide. NEVER use sand or any grit that contains SILICA in a sandblaster unless you have an excellent dust collection system, the cabinet does not leak and you are wearing a P100 fullface respirator!!!

N95 is prefectly adequate for sandblasting. We did a study on N95 vs P100 for exposure to a carcinogen at work and found the N95 to be more than adequate. Actually, you can use a filtering facepiece - that's a disposable respirator for dust. The difference between P100 and N95 all goes to how NIOSH ...
