The Royal Foundry in the Royal Lazienki Museum in Warsaw provides an Instructional video that shows how to prepare a cast of traditional gypsum ornaments from ready-made forms. The Royal Foundry has been operating since the 18th Century teaching crafts, in which plaster copies of ancient and modern sculptures were made. Gypsum castings were popular in eighteenth-century collections of European monarchs. Currently, the studio is conducting workshops for students of various schools during which students learn about the famous antique sculptures and related myths. The instructional film shows the casting of a floral motif.
