Instructions
Find Stangl with the Stangl name, or look for precursors to Stangl like Vase-Kraft or Fulper, which became Stangl Pottery in about 1929. Most of the 20th-century Stangl is red clay pottery, and they are famous for hand-painted birds. Stangl Pottery made hand-painted dinnerware that is also collectible.
Look for TAC marks for Trenton Art China (or look for the TEPECO label). Much of the Trenton Pottery looks like Abingdon, and is a white clay pottery. They made an elephant, but very few animals or small pieces of pottery.
Locate Cordey Pottery, often marked Cordey in script, with a shape number. Some pieces have a label that is CCC for Cordey China Company. Some pieces are marked Cybis, since he worked for Cordey when he first came from Poland. Cordey often has lavish hand-decorated roses and lace in a Rococo style. They made male and female figurines, and bird figurines.
Find Vontury Pottery, marked on the bottom with a hand-signature on a light beige clay. Much of his work is impressionistic style art, often flowers.
