In late 2006 I used a couple of 12-packs of Kerr lids when I was
pressure canning green beans. Opened the last jar yesterday and noticed
that the lid was hard to get off with the church key and, when removed,
had left a lot of sealant on the jar. Remembered that happening with
most of the Kerr lids used on the green beans. From this I am going to
postulate that the sealant was not the usual sealant on jar lids as I
have never had that happen before. The jars were all sealed but just had
the problem of the sealant sticking to the jar when opened. Any opinions
or ideas?
