What are Zsolnay porcelain marks?

Zsolnay porcelain marks indicate the manufacturing date range of each individual ceramic piece. For example, a Zsolnay porcelain mark of 689 would indicate that the piece was produced between 1873 and 1882, while a mark of 5,770 would indicate that the piece was made in 1900.

Established in 1853 by Miklós Zsolnay, the Hungarian company quickly earned worldwide fame for its one-of-a-kind earthenware and stoneware pieces. It is important to note that the Zsolnay did not mark its pieces between 1853 and 1873. Those pieces are authenticated by ceramics specialists, who use their Zsolnay knowledge and observational experiences to determine the date range.
