All round parts - plates, bowls, vases - are formed purely by hand on potter's wheels and not, as customary in other manufactories, by means of a roller machine. Due to the time-consuming manual production, the Nymphenburg porcelain is significantly thinner, even if the handcraft takes more time. Firstly, the porcelain mass required for throwing is shaped into a so-called “hump” on the wheel head driven by water power. Under the skilled hands of the potter, lumps of clay are thrown into thin plates or bowls, which are then given their final shape on a plaster mold. Nymphenburg's repertoire comprises a good 20,000 different pieces. Each one is provided with the Nymphenburg embossed stamp and the craftsman's initials.
