Bavarian china typically has a mark on the bottom that indicates the piece is Bavarian. This identification stamp will contain the word "Bayerische" or "Bavaria" along with other markers like initials or small images, according to the antiques and collectibles website My Granny's Attic. One common image often used on Bavarian china is a crown.
This type of China came from manufacturers in Bavaria, Germany. It came into prominence in the nineteenth century and continued to be a popular china form well into the twentieth century. Fine Bavarian china possesses a vibrant white color, and its porcelain is often decorated with bright and colorful images, such as flowers. Since these china types are usually considered antiques, a dealer or buyer specializing in antiques can likely provide insight into the authenticity and value of a given piece.
