Broken slumped bottle lamp shade
Posted: Fri May 23, 2003 10:42 pm
A fused, then slumped lamp shade made of the small perrier bottles came out of the kiln today split on opposing bottles.
Here is the firing schedule;
225dph to 600o-no hold, 300dph to 1200-held for 15 minutes.
The kiln was supposed to go up to 1325 and hold there some, but when I looked at the piece after the 1200 hold it had already split on opposite sides. I'm hoping to send a picture along, but in case it doesn't work.... the splits went from the middle of the the bottle tops down the middle about 3 or 4 inches.
What did I do wrong?
Thanks for your help in advance.
