How to tell age of canning jars? and more...
Well I scored good off freecycle today.
Two different people gifted me with canning jars in repsonse to my wanted ad. Now one lady gave me about 40-50 jars. Looking at some of these I am thinking they are WAYYY older than I am used to seeing. How can you tell the ages of the canning jars? There are all kinds of different ones. Kerr and Ball and a Presto(never heard of that one) Also there are some that have the ball signature on the bottom butthats it. Are these normal canning jars. There are some jars that dont have ANY differentiating marks/brands, BUT they are heaver and thicker than the canning jars. A couple are really pretty. Of course there is a hanfdful of jars that look like grocery store jars too. This woman said she hadnt been able to can in years and most of these jars they had just empitied stuff that had been canned since like 1980. THere is lid goo on the edges that is peftirifed on.. How do I get that off?
