To identify plates from Limoges, France, first look at the bottom of the plate. If there is a hand-painted factory stamp with the Limoges, France insignia and a printed stamp that says "hand-painted" in French ("peint main"), the plate is most likely authentic. If the porcelain plate has a "C" or "RC" stamped next to the insignia, it is an imitation produced in the Republic of China.
Animals, people or landscapes should look hand-painted when it is inspected. If it is a floral design, it should be a transfer decal specially designed by the factory. On close scrutiny, it is possible to see the transfer decal under the final glaze. If the design is of fruit, it should be larger than the designs used by most other porcelain makers.
Genuine Limoges plates are made over or under a layer of glaze, which is a gloss or non-gloss coating. Different types of glaze are used to protect or augment the artistic effects on the porcelain plates. Glazes can be identified by their slight or intense shine or a crackled effect.
Look for marks on plates from small fabricators such as M.Redon, C. Ahrenfeldt and France C.A. Depose that do not include the "Limoges" name in their marks. Some manufacturers also placed pictures of birds or butterflies in their marks. R. Laport used a butterfly above the initials "RL/L," and Latrille Freres used a star under the words "Limoges France." False pieces are also much cheaper than authentic Limoges plates.
