This is a German porcelain RS Prussian mustard pot with a pedestal foot and a notched lid. The date is circa 1879 to 1914.
The mustard pot is 3 ½" high to the top of the finial and 3 ½" wide, including the handle. It is a small and delicate item.
The mold is number 608, which is known as having an "elongated scalloped border." You can view this mold in the book by Mary Frank Gaston, "The Collector's Encyclopedia of RS Prussia," page 143, Plate 371. The finial is in the shape of a flower. The handle is trimmed with gold.
The decoration is one of pink roses with purple leaves against a green and cream ground with a pearlized lustre finish. The elongated scallops are accented with red and gold.
The inside of the pot and the underside of the lid are glazed white.
The scalloped edge of the mouth feels a bit rough to the finger tips, however there are no nicks or chips, so it must be due to the nature of the irregular edge caused by the elongated scallops. There is no crazing, and there is minimal wear to the gold trim.
The mark is red, RS Prussia with the star and the partial wreath. There is no mold mark. This mark means the mustard pot came from either the Suhl or Tillowitz factories.
