Although industrial china is often bisqued high (so it can be
supported while being fired to the clay body’s maturity) then
glazed lower (using binders and gums in the glaze to help it
adhere to a body that is no longer porous), studio potters
usually bisque lower so that the work remains absorbent and
The name “porcelain” was given to translucent vitrified stoneware in China by the explorer Marco Polo in the 13th century. He thought that it resembled a certain seashell named genus porcellana because of its high gloss and translucency. Porcelain is made up of a high temperature (2400° F) fusion of fine white clay and feldspar. To make a sculpture like the Boehm birds, the figure is first modeled in clay or wax. A mold is made from the figure (or many molds in the case of complex figures) and a cast is made by pouring the fine porcelain mixture into it. After the lining of this mold has hardened, the liquid center is poured out, and the mold is removed. At this time if the model was made in sections, the sections are assembled, and fine details are added by hand. The figure is placed in a kiln for twelve to 24 hours, then cooled for three days. At this time it is in its “bisque” state, and may be colored and then glazed, if desired.
I think that this is saying that a high bique was used (vitrifying the body), and a later
glost stage was optional. Obviously there would be the usually difficulties in applying
