glaze crazes in reduction but not in oxidation ?

Oct 21, 2003 3 Replies

i have been using a glaze in cone 6 ox for a while .about a month ago i had my vent closed a little to much ,so it was a little reduced and i liked it.so the last kiln i fired it in reduction .i realy liked some of the colors but when i held them in the sun light i saw they were crazed .and i never have problems with crazing in oxidation.one bowl i did with a copper green glaze i use, the bowl came out half red half green looked good but the red was crazed and the green was not.thanks for any info .

I am searching for an answer for you.

However I have one question.

If you have a kiln that you can fire in reduction why are you firing oxidation?

i have worked in production pottery for about 10 years ,and oxidation is all i have been around. i got a kiln about a year ago so now i am working for myself.when i saw the copper green turn red i decided to try to do reduction.
