Re: Dealing with bubble in glass

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...

Re: Dealing with bubble in glass

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...

Re: Dealing with bubble in glass

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...

Re: Dealing with bubble in glass

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 ...

Re: strong, but thin gloves?

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.

Re: strong, but thin gloves?

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...

Re: No Days glass fusing glue

You might ask the No Days people: https://nodaysadhesives.com/No-Days-Liq ... g-c5749935

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.

Re: controller for small Aims kiln

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?

Re: controller for small Aims kiln

I do not need anything fancy.. I will be adjusting the firing as it happens. So, hoping there is an affordable off-brand unit. If you're going to be beside the kiln during the firing, you might just need a pyrometer, instead of a full-fledged controller. That would give you the temperature in the k...

Re: Is 4 fuse firings on a piece too many?

You can fire 4 or more times, but you have to be careful, the lower the temperature the better. If you fire that particular piece to a "higher fuse temperature" you're going to lose the texture or distort the design, which may not be what you want. What exactly do you mean by "spider ...

Re: What to use on a 3mm piece of base and 3mm dichro

You can sift a very thin layer of clear powder (two grains thick at most) over the entire top of the piece.

Or use dichro on clear and fire upside down.

Re: 21 year old Skutt Clamshell kiln issues

That's an odd situation. Normally, if elements were bad it would generate an error message (Failure to Heat) before it started cooling.

Has the problem repeated itself? Have you double checked the firing schedule to make sure you programmed what you thought you did?
