To identify Limoges marks, turn the porcelain piece over and look for one of the standard Limoges maker's marks such as the "Limoges Meissna" mark or the "Limoges La Seynie" mark; examine marks closely using a magnifying glass, as some manufacturers incorporated pictures into the standard markings. Other standard marks to look for include the "Limoges Elite L" mark, the "Limoges Chambon" mark and the "Limoges W Guerin" mark.
Limoges porcelain pieces all carry maker's marks because the French government required it since the start of production. Identify the maker's mark on the porcelain by comparing it to the standard marks.
Look for an impressed "AE" marking. This marking indicates an old piece created by the Allund factory sometime from 1797 to 1868. Also look for pictures such as a butterfly above the letters "RL/L," which indicates a piece created by R. Laporte.
Check for another common marking in red and green that reads "Elite France." The "Elite France" mark identifies a piece created by The Bawo & Dotter company of New York. If the marking is red, the piece was created between 1900 and 1914. If the marking is green, it was created between 1920 and 1932.
The "Limoges coiffe" mark is another common mark that consists of a star with seven points that has the word "Limoges" printed inside it, with one letter in each point of the star.
