I needed some quart canning jars the other day, so my generous sister gifted some quart canning jars to me. I noticed a few were different. For comparison, I had Mr. TellBlast get my old (not quart) jars out of storage. They are blue. I have the accompanying old tin lids some where.
I was able to date the Ball jars as manufactured in the early 1900’s. Sara gave me some jars from Atlas, Kerr, and a couple other places, which I could only roughly date with the help of a bottle collector website.
I like the thought of drinking from an old jar and holding history in my hand.
See here to date your jars.
