Q: I have a plate with this mark picturing an eagle above the letters "C.T." Who made it? Is it old?
A: This mark, used by C. Tielsch & Co., was registered in 1875 and was used until c.1935. The company was founded in Altwasser, Silesia, Germany (now Walbrzych, Poland) in 1845. Household and hotel porcelain were made. It became part of C.M. Hutschenreuther in 1932. Pieces marked "Tielsch" or with the initials "C.T." continued to be made until at least 1952, when the Altwasser factory was nationalized by Poland.
