Question
QUESTION: Hi you helped us before and I'm hoping you can again!
We recently had to replace our thermo cupple...the last two glaze firing's some of our bowls/cups are losing their shape...what is causing this and how can we fix it
Thank you
Kristi

ANSWER: Dear Kristi,

    Thank you for your recent question. I am glad you returned to AllExperts for additional assistance.

    Bowls and cups can loose shape during a glaze firing when the firing is performed too quickly or the kiln is heating faster than normal. Try slowing your firing down in the first 1000 degrees by raising the kiln, or other words, ramp the temperature at 200 degrees F per every 2 hours until the kiln reaches 1000 degrees, then fire normally. This should correct the problem.

    I hope this helps you. If you have further questions, or this solution does not solve your problem, please feel free to contact me again. I am always at your service. My apologies for the timeliness in the answer. I was away on a family emergency.
