Re: dalle de verre - Wiesenthalhütte

Can you post some pictures, and possibly a small inventory of colors/types?

Thanks

Re: Tack fusing frit balls

Basically, if they can't stick in the spot you want without adhesive, they're going to move when the adhesive burns off. And if the schedule runs too fast, causing the glass to move, they are also more likely to slide around. So...gentle schedule, perfectly level position, and a layup that secures t...

Re: low tech screening

Vonon, check the size of your pictures (in kilobytes, not the dimensions or resolution). Usually when my pictures are rejected it's because they are too large. The attachment utility (Upload attachment, below the message box) has a limit of only 400K. If your image is more than 400K (or, actually, i...

Re: Over Annealling

You're a WHOLE LOT better off than if you'd programmed in a 9-minute anneal soak... ;-) Seriously, you're at 4x your planned anneal soak. Unless your kiln is way off on temps and full of hotspots, so that the air around one side of that pattern bar was maybe 20 degrees cooler than the air around the...

Re: Path of least resistance...

That's one of those "how long is a piece of rope" questions, anyway... A 15-pound casting might be a piece of glass about 10x48 inches and a half-inch thick, or a cube about 5 inches or so on a side. How long you'll need to soak it depends on the thickness of the glass, the type of glass y...

Re: Adding a blank ring question

It would make a difference in that you're increasing the amount of air being heated. Your kiln is currently 8x8x4.5 inches, or about 288 cubic inches. If you add a 2" ring, you'll increase that to 416 cubic inches. Add a 4" ring, and you'll increase the air you're heating to 544 cubic inch...

Re: Best COE red glass for high fire melts

You have to move to casting glasses to find a red that will work in high fire melts. Look at Burnt Scarlet Striker--it holds up very well to the heat. It is not a pure fire-engine red, however--it's got a bit of an orangey cast and is a little dark in thick castings. In thinner applications, such as...

Re: damaged kiln shelf

You might try putting refractory cement into the holes, packing it in and firing according to the manufacturer's directions. I don't think it's a permanent fix--if I'm not mistaken the cement and mullite have different expansion rates so eventually the cement will pop out--but it should last awhile....

Patty, probably the saddest words I ever hear a fuser say are "but that schedule always worked before..." especially because they usually say it right after it stops working... ;-) So...you've got a 14" Skutt firebrick kiln (The Firebox?) with a 13" black glass disk on a vermicul...

Re: source for float glass

Cullet would be interesting in a tack-fuse; haven't tried it but I don't see why it wouldn't work. Thing to remember is that cullet is thickish, so two pieces of cullet together are going to make for a fairly long anneal schedule. My best sources for float are usually salvage or commercial resale pl...

Re: Soft sandblasting media

Peter's had luck with soda blasters and at some point I'll try one. Right now, though, I've got a plain old power washer that's doing a wonderful job of removing all mold residue, so I haven't needed to change anything.

Re: using a torch

I don't guess it'd be a problem as long as you didn't let the glass get down past the strain point, i.e., no part of the glass got cold enough to thermal shock. But it'd be a lot of work and probably not all that much faster than just closing the kiln back up, having a cool drink and letting it come...

Re: How to make perfect oval cabochons like from Etsy

Are you sure you want cabochons? Cabochons, almost by definition, are pretty domed. Are you just looking for flat ovals of glass? If you can post pictures of what you want, top and profile views, it'll be easier to tell you how to achieve it. Basically, cold shaping trades off with hot in glasswork:...

Re: Removing Plaster from Mold

I got it on eBay a few years back, a DTE piezo ultrasonic dental scaler is I think the proper name. You can get them for somewhere between $110-$175. If you want the fancier models with built-in water reservoirs and more settings/features, they're about 3-4 times that much.

Hi, Debbie; Yep, familiar with (and like) your flameworked paperweights, saw many at Corning (do you live near there?).

Re: Removing Plaster from Mold

Well...I spent years and years trying to figure out how to get spent mold material to release cleanly from a mold, discovered a lot of tricks (one is eliminate as much silica as possible from your mold mix, and a dollop of kilnwash in the face coat is another). But I also learned that there's defini...
