hey guys, today i opened up my brand new pressure cooker and decided to try and get a liquid culture going, having found the karo in a cupboard. sweet. heres my question, im not too familiar with pressure cooking, though ive read my manual first for safety reasons. but apparently after pcing a half pint jar at 15psi for 20 minutes and letting cool for several hours i noticed a heir-line crack along the bottom of the jar. no water seems to be leeking so i dont think that it is letting any air our or in.....though im debating tossing the jar i am wondering if its ok to inoculate as long as no noticeble leak is present. ??????
also how can i prevent the cracking, the cooker came with a thin rack that i used. and if it makes a difference i loaded the 8 qt cooker with 2 quarts of water (about an inch up the half pint ball jelly jar. maybe a towel in the bottom of the cooker would keep too much heat from transfering through the rack....what do you think?

Hey, you used the rack and seem to have had enough water, so I think your jar just cracked, it happens. Maybe a flaw in the jar.

If I were you, I'd make up at lesat 2, if not 3 more 1/2 pints of Karo. inoculate each one with 1 CC of multi spore and incubate. If you start with a couple, if you have any problems, you should at least wind up with one good one.

Good Luck

Peace,Love,Happiness and Harmony.

Once in a great while, a mason type canning jar will develop a crack, from an air bubble flaw, chip or whatever.

Maybe 1 jar in 300 PC runs of multiple jars, if you are doing it right.

Jars are cheap & I would gather - quality control is not all that great.

If you run a PC dry, with the heat on high, you get cracks.
