How do I identify French porcelain marks?

One way to identify French porcelain marks is to take a photo with your smartphone or tablet and then perform a reverse image search. Often, doing so will allow you to quickly determine the maker. If this approach fails, explore trusted online resources with photographs of the markings associated with various French makers, such as the crowned N of Sèvres and the H & Co. insignia of Haviland.
