Canning jar breakage - WTF?
I am a 20+ years of experience canner but this season I have had more jars break than ever. What is going on?
1. I am using a steam canner.
2. The jars are all fracturing at the bottom - it is breaking off in a nearly neat circle from the jar.
3. The jars are cold packed pickles.
My first instinct is thermal shock.
I am switching back to the water bath method - although I have used steam for decades with no issues like this.
I am currently waiting for the 3+ gallons of water in the water bath to come up to temp...zzzzzzz....this is why I switched to steam. But if thermal shock is the problem, perhaps this will be the solution?
Like most of you, I am reusing jars that I have had for years, though there are some new jars in this batch.
Thanks in advance for any information or thoughts.
