Identify Limoges porcelain plates by looking at the porcelain mark, which should say Limoges, denoting the name of the city in France where the piece was produced. Genuine Limoges plates are also often signed by the artist with detailed hand painting.
Because there are dozens of porcelain companies established in Limoges, France, producing porcelain, genuine plates can have many different marks. However, Limoges should appear somewhere in the mark. For instance, Limoges dinnerware from Blakeman & Henderson has a circular mark. At the top of the mark is Limoges, and at the bottom is France. Through the mark runs the company name B. & H. Another porcelain mark comes from the Coiffe company in Limoges. The mark contains both Limoges and France with a seven-pointed star in between the two words.
Limoges porcelain plates by the Old Lanternier Company can be identified by fluted edges, gold and silver trim, scroll-like patterns, flower borders, and vines framing the perimeter of the plates. A limited series of plates are decorated by war images and motifs. The back of the plate contains not only the maker's mark but also a series of number identifying the particular pattern, of which there are over 400.
