What happened?
Hi all,
This is the first time it happened to me and I need to understand....
My firing schedule:
300/h to 1150 h10
50/h to 1250 h0
600/h to 1490 h20
and anneal
It works fine for me in my other kiln... this is a new kiln (4th firing) and a new shelf (1st firing). I am thinking that the problem is the new shelf.
I kilned washed as usual and it was dry (more than 2 days in an AZ garage). There was other pieces of glass in the kiln and they are fine (they were on another shelf that was not new).
What do you think? I will apreciate any input.
Thank you in advance,
Patricia

You're welcome. Incidentally, this part of your shedule: "600/h to 1490" is the main culprit. If you slow down between approx. 1150 and 1450 these kinds of bubbles are less prone to happen.Patricia O'Neill wrote:Thanks, Brock!
My memory is so good, I can't remember the last time I forgot something . . .

It's hard to say, the only way you can tell you've gone too fast is when . . .Patricia O'Neill wrote:Which rate would you go from 1150 to 1450?
(for larger pieces, 2 layers of Bullseye 3 mm)
Thanks again.
Patricia
I probably go 100-150 F per hour in that range.
