I remember when they changed the mayo jars so the canning rings wouldn't work on them to prevent people from using the empties for home canning.I remember when a LOT of stuff came in glass bottles. Ketchup, mustard, mayo (and its non-friend, M-whip) instant coffee...
I still have a glass Taster's Choice jar in the cupboard for collecting pennies.
They claimed it was a liability issue.
I had one of those old glass coffee jars full of mercury for a long time.
