Q: I have some plates marked “Edelstein, Bavaria, Maria Theresia.” There’s also a number I can’t read on the bottom. The plates have a plain center and a slightly scalloped edge trimmed in gold, gold leaves and flowers. Can you tell me who made them?
A: The Edelstein Porcelain Factory was located in Kups, Bavaria, Germany, from about 1934 until a few years ago. Dishes marked “Maria Theresia” can be found with several different decorations, so it may be the shape’s name. The number is a pattern number. Maria Theresia dishes are part of an inexpensive line. A plate is worth under $10.
