Does anyone know whether there are any health or safety concerns associated with dishes, bowls, cups, etc. made from Melmac (or Melamine) in the 1950s? I've been eating off dishes from Prolon's "Florence" line, designed by George Nelson & Associates in the early 50s, for some time. Sometimes, and only with respect to the coffee mugs, I've noticed a chemical sort of odor emanating from the me. I usually throw out any items that have such smells, but I worry that even the ones that don't have this odor might be somehow hazardous.
By the way, what exactly is "melmac," and how does it differ from the sort of hard plastic dishware that one finds these days?
Any info would be appreciated.
