Yep. The key word is carefully. And just peek, don't hold it open very long.

The second kiln fires hotter than the first, so you'll need to reduce the top temperature (from 1325 to something less than that). Exact temperature depends on the particular kiln and degree of tack you want. Try 1300 and watch the kiln to see if that works. If not, go higher or lower than that to h...

In great shape. $300 or best offer.

I guess it depends on how low you can go and still achieve the slump you want. The lower the better, the shorter hold the better.

You could test with a scrap to see if you like the resulting texture.

The answer is going to depend on the color, but typically powder shrinks up to 1/2.

Why do you want the powder so thick? Can it work with a layer of thin (2mm) and a little less powder?

At 1250F most of the sandblasted surface will start to shine.

If you can, go to around 1125 and hold for an hour. That works for most shallow molds and will leave you a very nice matte surface. (My favorite finish, by the way.)

In excellent shape. Current retail $2200+, asking $1000 or best offer.

Molds, shelves, and other related supplies also available.

Kiln is located in Greensboro, NC. Must pick up.

If I was trying to fix it though, you're saying put clear frit in the space of the bubble? Would that help the bubble flatten or would it just smooth out the the divot? If I wanted to keep working on the piece, I'd probably break the bubble and put frit or small pieces of glass where the bubble is....

I refired my second piece and ended up with a small bubble going the other direction and was wondering if anyone had any feedback. It's hard to tell without a better photo, but my guess is that when the original bubble happened it stretched the glass in that area and you didn't have enough thicknes...

If I want the glass smoother, rather than more like a task fuse, how long do you recommend holding it at the top temp? Or is that more a matter of what the top temp is? The smartest thing to do is to keep the hold time the same and just vary the temperature. 10 minutes is a good standard to use. If...

Also, when I refire, I was thinking of putting fiber paper on the bottomto help with airflow around the piece. Can I put kiln paper (I have Bullseye Thinfire) on top of the fiber paper to try and mitigate the rough texture or would that defeat the purpose of the fiber paper? Is fiber paper somethin...

Not long enough for a bubble hold. You need to hold at least 30 minutes at 1230F on the way up. Too fast from the bubble hold to your top temperature. 200 dph at the most. Too long a hold at the top temperature. Lots of lousy schedules at Makerspace and Reddit. As for refiring the damaged pieces, yo...

In general, it helps if you give us the firing schedule you used that caused the problem. The bubble was likely caused by firing too fast between 1200 and your top temperature. If you share your schedule we can answer more definitively. Slumping the piece won't fix the problem. And you can't fix it ...

We mostly use 5 mil, which might be easier than 9 mil to get on and off, but they're still hard to remove, especially if you're sweating.

Vinyl gloves would be easier to remove, but they're not very durable.

Here are some options: Nitrile gloves, durable and resistant to puncture. Not quite as flexible as Latex surgical gloves, which are more prone to puncture than nitrile gloves. Vinyl gloves are thin, but prone to puncture Neoprene gloves are designed to replicate latex (some people are allergic to la...

Don't know if it will work for you, but hot glue is polymer based so shouldn't be water soluble. It burns off pretty clean, but you may want to test for your application if you try it.

We've had good luck with both scotch tape and clear packing tape. Just don't lay it on too thick.

Wondering about the infinite switch. When it's on low, do you see the elements clicking on an off infrequently, or are they mostly on all the time?

Is there a difference between the switch on low and the switch on high?
