This a Set of 4 beautiful 10 " dinner plates, and cups with saucers in excellent, condition, shows very little wear on the inside, and out! pattern is clean.  No signs of dishwasher glazing. Little to no wear on the inside, bottom shows slight wear as most of these pieces do from years of use/storage. This set was really taken care of through the years. Truly in amazing vintage condition, as seen in the pictures.  These are a hard, rare find as they were only made for a limited time. 4-Dinner plates, 4 cups, 4 saucers, 12 pieces total. Corning began producing Centura in 1966 and ran it until around 1977. Though it is a form of pyroceram it is not glazed (Corninware IS glazed). The glazing is one of the things that makes Centura look like fine china. Centura came before Vitrelle (Corelle) and IS NOT microwave safe. Microwaving overheats the plate and leaves the food cold.
