I just got through canning pickles. The first batch went perfectly. The second batch, I had three jars that broke - the bottoms came right off while in the canner. Does anyone know why this would be? My dad said maybe because it was the second batch, the jars had cooled off (before I filled them) a little too much. (I always warm the jars up by running them through the dishwasher...) Someone else said they probably were cheap jars or had a crack in them that I didn't see. What do you gals think?

screw the lid to tight? maybe an older thinner jar that may have has a slight crack you missed. That sinks ... clean up is not fun.

I tend to agree with your dad. If this was the second batch and you used the water from the first batch that was hot, putting cooler jars in will cause them to break. Visa versa happens too - hot jars into cold water. They always break in a circle around the bottom and you don't even know it until you lift out the jars and all the food goes everywhere! So sorry it happened. I know that was a disappointment.

That's so interesting, Mary Beth. I've never had that happen (and...oops! I've never warmed my jars?!) I'll have to remember this for the future when I'm making my jelly in the spring--I don't can like I used to with the wee one about (though I absolutely should be), but this is one of those "cooking is science" sort of happenings.

I agree with all the above info, but also, are you setting the jars on the bottom of the canner or do you have a rack. This also will crack jars. But first of all, the hot to cold or cold to hot would be the culprit. Good Luck! Happy Canning! Farmgirl #946 Linda

Thanks for the information ladies. I do think it was the cooler jars into hotter water. Ah, always something to learn, isn't there?

Same thing happened to me yesterday with a batch of whole tomatoes. It was cooled jars, I'm sure. I sat the second batch in hot water in the sink before putting them in the canner and they were fine.

I canned salsa last night and did the same thing, put cold jars into a hot bath, but luckily mine didn't break but they were brand new jars. Wonder if the glass wears down over time?

Deb- Yes- any shock to the glass can cause micro fractures and stress in the glass to the point where one day it will break

I always heat up my jars before I fill them and process.

I always warm up the jars before I fill and process as well, but I've never done two batches of pickles back to back. I use the dishwasher (sanitizing cycle) to heat the jars. So I had 14 jars ready to go, filled seven, processed for 15 minutes and then went to fill the next seven jars and apparently that 15 minutes of processing (plus filling time) was too much for the jars that had just been run through in the dishwasher, and they cooled off. Bum deal, guess I will heat each batch separately next time. :)

I know with summer heat we hate to turn on our ovens, but my mother always put the oven on warm and kept the jars in there until she was ready to fill them and process. (that was before dishwashers of course!;)

Lesley that sounds like something to try. I have not done a double batch of anything so I am using the jars right out of the dishwasher but, now that I know what has happened to others I will be sure to watch out when I do the salsa I hope to make this week. Thanks ladies.

I set my full jars in the rack, but not in the water, for a little while to let the "second" batches or raw pack/ cold pack jars heat up a bit before dunking them down into the pot. My jars are clean, but usually not hot when I fill them. It's worked for me for many years and I rarely have any jars break due to hot water and cold jars.

What do you use to get out the air bubbles? Be sure not to use a knife because it can cause microchips in the jars that weaken them too. You can use the plastic tool that Ball sells or even a wooden chopstick. Just nothing metal.

I had one break off last month. Luckily I used tongs and got it sideways and out before the whole can of tomatoes spilled into the water. Then I went fishing for the bottom. It was perfectly broken not jagged at all. Either it was a fault in the jar, or it was sitting too much on the hot bottom of the pan, and not on the rack enough.

I think the key is in the balance of hot and cold. You can use cold jars and cold canner water, so that both jars and water heat up together once in the canner or hot jars and hot canner water but both have to be of a similar temperature. I've had it happen too for that reason.
