This is a Carl Tielsch (CT) Altwasser antique porcelain divided oyster dish, likely dating from the late 19th century. It features a floral design with gold accents and a distinctive handle. The dish is divided into two sections, commonly used for serving oysters or other delicacies. Carl Tielsch founded his porcelain factory in Altwasser, Silesia (present-day Poland), in 1845. The factory's products were known for their high quality and artistic merit, often compared to those from Berlin and Meissen.
