The goblet shows the portrait of King August III of Poland, during the brief period when the Polish throne was claimed by the electors (dukes) of Saxony. The portrait is made of red opaque glass that has been pre-formed by pressing it into a mold and finishing it with some engraving. It then was glued onto the surface of the goblet's bowl. This was a way of avoiding the costly and difficult process of engraving the portrait in high relief into the bowl's surface itself, and allowed for serial production in relatively high numbers. While many Saxonian goblets are known to bear colorless portrait pastes, the red opaque seems to be quite unique. Red opaque glass was produced in Saxony, perhaps in competition to red stoneware, the Böttgersteinzeug.
