Fabulous Fenton set of 5 Ivory Crest 8" Plates. Round Platter- perfect for serving tea sandwiches, desserts or appetizers. The color is a custard yellow with clear edge. The Ivory Crest line was introduced in 1940 and discontinued in 1941, because of the uranium used……the Atomic Energy Commission pulled all of the uranium in the US for use on the Manhattan Project in support of the war effort. Making these pieces are very rare. *They will glow under a black light due to the uranium salts used in making the color. Don't worry- they are safe- they don't cause radiation. In great condition with no chips, cracks or crazing. Yes they glow with a blacklight!!
