I'd forgotten about them for years, saw some at a local church sale where the lady had some lovely, brilliant colors in them.
I still have some that I swear must be over 40 years old, and they are still going strong. Lost the lids on some, but they sure do hold up. Getting real pricy now, but probably will be still in use when my GGDs start cooking. Sometimes it pays to get the best, instead of constantly having to replace something.
