I have a question. I have recently been given a bunch of jars. There are canning jars but also jars that are not, mayo jars, etc. I noticed that when I went to pick them up, there were still food items actually "canned" in the non, canning jars. I personally would not use these for canning but would they work for dry goods storage such as pasta/rice/etc, if propperly sealed with a vaccume sealer (provided they stay sealed) or O2 absorbers added?
