Dating Old Canning Jars
I have a lot of old, vintage canning jars. I love the history they carry as well as their charm and character.
While it is okay to use them for storage or even as a refrigerator container, you should never process old jars in a canner. The old glass can’t take the temperature change and might shatter – which would be such a shame. Plus, the old fashioned sealing method is not reliable. But vintage jars are great on your pantry shelf to hold grain, etc.
So if you have some old jars, how do you know their true age?
If you have a Ball jar, you can date most of them just by looking at the logo. Every few years, the Ball Manufacturing Co changed the logo and if you compare yours to a reliable chart, you know how old it is. All you need is a chart like the one below.
I found this great chart on Pinterest, but unfortunately, it had lost it’s original link to the source. But Thanks to Sean at PunkDomestics.com for sending me the link here: Go to THIS website for a TON of information on old Ball canning jars. A must read! Just compare your logo with the ones below and you have a general idea of the date. There are a few other logos not shown here, but these are the most common.
PLEASE NOTE: I am getting a lot of emails and questions in the comments about the value of people’s jars. I’m not an expert in this area and I cannot tell you the value of your jar. Your guess is as good as mine.
I just love to collect them. Their value to me is sentimental.
If you have an old jar you want to sell, I suggestion you check on ebay to see what similar jars are selling for. Good luck!
