WHat are the chances of the glass containers shattering due to the heat expansion during sterilization? I havent tried it myself, but i have had experience of glass breaking when surrounded by heat?

Using a wash cloth works well, although I have never had any breaking glass even eith out it.
Usually class breaks because the expansion.contraction is too fast, since the specific heat of water is pretty high, this is pretty hard to do.

Things expand when they cool if I am not mistaken.

things shrink when they cool off PV=nRT if youve taken any chem or physics. they shouldn't be breaking if have enough watter in the PC and make sure the lids arn't on all the way so air can get in and out of the jars. then when there done sterilizing don't try to cool them off faster with cold water, just let them sit on the counter and cool down slowly, don't seal the jars till they are cooled down almost all the way.

BigBlackNinja is absolutely correct. If you have a holes already punctured in the lid then you do not need to worry about lossening the lid. Just make sure it is covered so no contams can get in. I belive water has weird properties though. If I recall right it actually expands when it cools, maybe that was specifically for ice. Ohh well.. doesnt really matter.

jesus I KNOW.. it was just an observation of ice properties. I already answered your question about glass breaking so i dont know why ur being an ass.

If you have holes in your lids or you keep them loose during the sterilization, and you allow them to cool slowly, they're unlikely to shatter.

thermal expansion that causes fractures occurs when a heated part of the faster than the surrounding or opposite side. generaly the thinner the glass the less the chances of breakage....best bet is canning jars
