Makers explored all kinds of applications in the new medium. Porcelain musical instruments posed enormous problems since during drying and firing there occurred substantial shrinkage. In the kiln, wet porcelain matter shrinks by a third of its volume so large molds had to be made to guarantee the precise final dimensions of bore, finger- and embouchure hole. Wooden flutes are easily fine-tuned and voiced by drilling; porcelain, however, makes later manipulations problematic.
