After a kiln problem in the 2nd firing of the piece the piece was not annealled properly.
Cooled kiln and kept piece in kiln then fixed problem . Re-fired piece to 1425 F. There are some
spider cracks in areas of the piece. The piece has some variations in thicknesses due to the
design. Thinking of re-firing again but to a higher fuse temperature and anneal for a longer time.
Feeling that I am being wishful thinking it might work but the piece is very lovely.
Any other ideas would be appreciated, Thanks, Val

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 cracks"? Generally, small cracks on the bottom of the piece are due to not enough kiln wash. Or are these different?
