Antique RS Prussia porcelain marks vary, but most commonly feature a two-color stamp of a wreath and a star, together with the words “R. S. Prussia”. The “RS” initials stand for Reinhold Schlegelmilch, founder of the porcelain factory at Suhl in Prussia ( present-day Germany).
The wreath on the stamp is usually green, with the words in red. Also a red five-pointed star appears at the top center of this arrangement.
Later on, a similar mark contained the words “R. S. Germany”. Not all R. S. Prussia contained the RS Prussia china marks. Many had no mark at all. Such pieces must be identified by the thin thickness of the walls of the items along with their exquisite workmanship.
The second image on this page may represent an RS Prussia stamp that is a reproduction, as it lacks the word “Prussia”, and the star is a green color.
