It’s nice that you can fix stuff.
When we would go to Missouri in the 70s, my mother would send me down to the basement for canned (jarred) vegetables, and say, “Don’t bring up anything with a date more than two years earlier than this year.” There were “cans” from the 40s down there, in the 70s.
After the fire in the late 90s, Dad and his cousin sold all the Mason jars as/is to someone who was prepared to empty them, sterilize them, and reuse them.
