The collection includes a great deal of Böttger stoneware, the precursor to white porcelain. They have a light red and brown coloring. When Prince-Elector August the Strong of Saxony founded the Meissen factory in 1710, white porcelain was not yet production-ready. Therefore, the stoneware named after its inventor, Böttger, remained the finest ceramic form available until 1713. August the Strong liked to give them as gifts to his high-ranking friends, which could have included Sibylla Augusta, as they knew each other.
