In reply to:

I think Helen is refering to melamine, a plastic made from resin, used for outdoor non-breakable plates, bowls etc.

PS I think that we are meant to be in miscellany by now but it is too late to move the whole thread.



Miscellany indeed... and when I interpreted melamine, the next thought to cross my fevered brow was "Qiana". Since we've gotten into the no-man's-land of 50s and 60s composite substances, I figured I might as well bring that one up ~
