The Mark with R S Prussia is for Erdmann Schlegelmilch. In 1869, his brother,Reinhold began manufacturing porcelain in Tillowitz, a town in upper Silesia. The "R S" in R S Prussia was actually named after their Father, Rudolph Schlegelmilch. R S Prussia starting out in Business in 1861, the Factory was located in Suhl, a town located in a region called Thuringia. This Germanic area was once part of Saxony was conquered by another Germanic state, Prussia, circa 1815. Some good information about the R S Prussia mark: Most R S marks appear to to have been applied after the second firing of the porcelain which produced a vitreous (meaning glass-like) glaze. As a result the marks are not "sealed." Although the mark would have been fired again,after it was stamped on the item in order to set it and give it some longevity, such a mark would not be permanent. With the passing of time, marks applied over the glaze in this manner can become quite worn or rubbed off entirely. Upon inspecting pieces which appeared to be unmarked until held up to the light: then a very distinct outline of the mark could be seen.
