The Red Wing Potteries the operated from the late 1800’s until 1967 when the pottery closed had 11 different ovals during their production history. These vintage Red Wing Stoneware pieces will either have the word "Union" or "Potteries" in their ovals. Without one of these two words, the stoneware piece is most likely a reproduction.
Below are some examples of the new potteries in Red Wing markings and logos.
