I should have elaborated. If you start with a circle, and have a form with a sufficiently wide base and relatively short height it will be less likely to give you the large deep folds, but more the multiple little folds. Something like an inverted ice bucket would be worth a try. Sounds like you are...

In my two big kilns I have floor made of two layers of low densiity brick with mullite shelves, and even with regular runs of over 1500 F, I have had no warping of the floor. One of my older kilns has only one layer of the brick, and the floor experiences "tides" on heatup and cool down.

Yep, knew it wasn't tin bloom since I don't use float, though it looks like it. How do you use the Mica Bert? Previously fused into the glass before slumping? Yes, cold working would do it, but would be cost prohibitive for my situation. I have shifted to glasses that do not show the haze, and used ...

A while ago I had to cut some deep inside curves in full sheets of Wissmach dense opal and doing it in multiple scores was not an option. I made a template for the shape, traced it in marker on the smooth side, flipped the sheet, traced it again, flipped the sheet scored it, flipped the last time an...

I too have experienced this. I have observed a very specific set of circumstances surrounding it. Project has been fused first, in my case on thin fire. Glass going in is free of visible devit. Project is slumped into stainless with the fused side down. Hazing is confined to only the upper edge. The...

Anyone interested in A Pattern Language might also enjoy "Human Scale", written by Kirkpatrick Sale. Read both years ago and they are still resonating in my cranium.

Brad-You're right about thermocouple type. I am using all K's, but am a bit dyslexic when it comes to keeping the J and K straight. As to degradation, I won't argue that it does not occur, but I will as to the severity. I have some thermocouples over 10 years old, with thousands of firings on them, ...

Lisa-Omega's number is 800-222-2665. I use part no. TJ36-ICSS-14U-12. This is a type J stainless sheathed 1/4" ungrounded. I use the fat ones cuz they can really take some hits and keep working fine. The thinner probes will respond faster, but are too delicate for the ham handed likes of me. Th...

I was surprised to hear what Evenheat said. I have been using Stainless clad thermocouples from Omega for many years and have never seen this effect. I have had rare failures, and they almost always are in the form of the thermocouple opening, in other words total failure. I once had one read correc...

Along with Berts really interesting result is what I have seen when I fire on stainless versus mullite. Stainless fires hotter. I have to drop the temp at least ten degrees to get the same result as I do for my 3/4" mullite shelves. The metal is reflecting the IR more effectively, and contribut...

I would agree with most of that Steve, except I am not convinced that the air is contributing much to the temp. measurement. Try shading a thermocouple from the elements and the result will be dramatically affected. I think what is being measured is primarily the IR impinging on the element, and bei...

I use thin fire paper exclusively. Haven't washed a shelf in 10 years. For my situation it is much more economical to use paper. Problems I had with wash was the required manhandling of the shelves, and the time to prep. Other issue was that if it was not done properly, the glass stuck and I lost a ...

Steve-Yet another opinion in case you were lacking! I have six kilns, and only two fire the same. Incidentally, the two that give the same results for the same time/temp profile are built the same. One way to get the same results for the same temps, is to vary the time. I could have done that, but i...

Depends on a bunch of variables Randy, but generally speaking for a single layer drape you can ramp up to 1000 in an hour, then afap to target temp, then a half hour of annealing in you have pleats touching, more if the glass folds onto the kiln shelf. As to the target temp, you will have to do some...
