glaze crazes in reduction but not in oxidation ?

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.
