However...I know people successfully use (and love) borax sprays and clear powder for devit prevention/concealing, but I'm with Stephen; they're just as likely to cause issues as to fix them. The better plan is to figure out what's going on with the glass/schedule/cleaning processes to cause the un...

Hi Al, that is the same arbor that I use, and I use a similar belt tensioning system. I opted out of the variable speed, which would have at least doubled my investment. I learned a lot about clearances for my large pieces and will be redesigning the mounting system. I just bolted everything to a ve...

I made my own "lathe" using parts I got from Covington (spindle), motor and mounts from Grainger, stuff I had around, and expandable drum from HIS. It was an 8" and was in the $75-$80 range. I use belts from HIS. It was pretty easy to build and works like a champ. I just drip water fr...

If you've still got wax in the mold after you've been steaming awhile, remove the mold and fill it with boiling water. Let it sit for a couple of minutes. The wax left in the mold will melt and rise to the top. Skim it off and pour out the water. I recently learned a nice extension to this techniqu...

A quick Google search reveals that "Keramicast" is manufactured by Saint-Gobain. Here a link to the physical properties of Kermicast . The site says "Keramicast is a formulated plaster used in the ceramics industry to produce working moulds for the slip casting of tableware. It is als...

In a word - YES, I think you are wasting your time. I doubt that heating on a grill will cause the chrome plating to come off. I know of some home remedies that MIGHT work. Your best bet is sand blasting. That is the most sure fire way I can think of. There are other "old wive's tales" tha...

I'm trying to do some frit tinting by using frit and powder. I've run a number of tests and really like what I'm getting in terms of the color range. What I don't like, is the bubbles I'm still dealing with. I use Bullseye medium clear frit and various powders. The mixing of the powder with the clea...

I've used both 120 and 220 loose grit in my small yard sale rotary rock tumbler I got for $5. It's belt was broken but it came with a replacement belt! I put about a pound of odds and ends of cut Spectrum or Bullseye sheet glass. I just randomly cut it up into 1"-2"-ish shapes. I then thro...

I guess I posted this and the link before we lost the archives - what a loss. Anyway, no shameless plug but here is all the details on my blog . I use the " Clean Shield® GEL - Shower, Tub & Tile Protectant". I've never found it locally, but you can get it from their website. As Havi s...

Another option - and one I use for my glass marbles, ordinary O-rings that you get at the hardware or automotive store. I use half-inch black or clear rings to keep large 3+ inch diameter marbles from rolling around. I was at an art fair a week or so ago, and everyone was amazed and that solution. I...

Will you be firing vertically or horizontally? If you fill it to 11" - that is a heck of large casting. Even laying down and damming the ends would be 6" thick. I don't have my copy of Stone right near me but the bigger killer is the slow drop in temperature which amounts to something like...

I'd be more than grateful!

Yes, that was my experience here in the U.S. as well. 3 tubes might be a lifetime supply.

Hi Havi, I use the "Clean Shield" approach - but this is only for sandblasted finishes - it really does make a difference. I've polished several large pieces both flat and rounded this way. I love the satiny finish it leaves. It is a little hard to come by - I posted about it on my blog a ...

And now for something completely different... I have a smaller version of this mold (mould for the rest of the English speaking world). Rather than deal with it in the mold, I do a very simple coldworking exercise after the slumping. A small amount of 80-100 grit and a few drops of water on a flat g...

I've gotten several private messages about the "tub and shower gel" that I used for providing a nice sheen on sandblasted pieces. It's a shame that the archives got corrupted - there was so much good info there. However, I did write an entry in my blog on this several years ago. http://gla...

might too much water be getting under the disc. Even if magnetic-backed, I've seen cases where too much water on the head will prevent the disc from firmly seating. Then the spinning forces (never sure which one any longer) throw the disc. I would check, as Cynthia stated, the cleanliness of the hea...

Harcuba, and others, use the wheels in a lathe, i.e. spinning vertically. It is really hard to source these wheels now. The sandstone ones need to be re-profiled every few minutes. They do wear away. The reason for dressing/profiling is the pores get filled with glass waste slurry and stops the cutt...

Hi, I really think it has to do with the costs of the medium. I think it would be great, if one had the space, to have a couple of cabinets, one with a course grit and one with fine. I get enough dust with the 220 grit, I suspect that 400-600 would just make a big dust mess. I get a decent finish wi...

I did some fusing tests with the powder a while ago. They are out in a box somewhere, and I have any pictures of them glowing, just in normal light. I used a dark transparent base layer, drew a pattern with the glow powder on top of that base layer, and capped it with a clear layer. I cut one apart ...
