What is melmaine? (looked it up its melemine) Very popular in the '50's and '60's. a hard plastic use for dishware... It was pretty much chip proof, hard to break, and a hard surface, so you could cut a steak or something on the plate..(dict. M-W 10th--a resin or plastic made from white crystalline orgain baseC3 H6 N6, with a high melting point)

I think it was a brand name--like tuperware-- but was copied frequently-- It something like "bake-lite" which is a brand name plastic use on pot handles-- it doesn't melt till heated to over 450 degrees (f) so you could start a an omelette in a frypan, and then put the pan in the oven and the handle wouldn't melt. But bake lite only comes in dark colors and melemine (still pronounced "mel Mack") was light in color and in heft. service for 8--45 pieces might weight only 7 or 8 pounds! you could "pop" melemine into a 200 degree oven to keep food warm (or to reheat)

I got some when kids where young--(28 years ago) and still have some left--(some got discarded) very hard to break!
