# Flexible Porcelain Mould Eperiment
Heading for a new way of porcelain moulding, this project rethinks the general rules of the plaster mould, turning it from a static to a dynamic element in the process. This is accomplished by compo- sing the mould of small plaster elements attached to a polyester textile. The mould then becomes a flexible surface, capable of taking on all different kinds of shapes that subsequently reappear in the porcelain material. Originally developed as a craft technique it can also be thought of as a method of customized industrial manufacturing.
In the porcelain casting process, plaster acts as a very important element, due to its special features. When liquid porcelain is poured into a plaster mold, the water in it will be instantly absorbed, and a dry wall is produced. With this special reaction, it is very hard to find a replacement for it. But the plaster is not necessarily bound to a fixed form.
The idea of achieving an alternative moulding process led me to think about segmenting the plaster mould into small modules that are interconnected and flexible. In a series of tests, the combination of triangular pyramid shaped modules and a polyester textile to connect them produced the most inte- resting results. Still, the traditional procedure of pouring the liquid porcelain into the mould is applied, but the mould itself can flexibly take on any free form. With their pyramid-shaped grid the resulting porcelain objects integrate both organic and structural properties.
During the moulding process, the plaster textile creates a flexible space between porcelain liquid and already existing forms, transmitting them to the ceramic material. With stones or a wire mesh a form could be easily arranged and copied. Also by putting the plaster textile on normal objects (for examp- le a dish), the original form will be copied. At the same time the surface will be connected with a geometrical architectural pattern.
# More possibilties for a mould
In traditional porcelain moulding process, plaster moulds need to be built rstly, in which liquid porcelain is lled. Consisting of CaSO4 Crystal, plaster solid is capable of instantly absorbing the water from porcelain liquid and solid wall will be formed in 3 to 10 minutes. After pouring the rest liquid out of the mould and taking off the mould, a porcelian body is shaped, which is prepared for late ring. To Think about the LEGO, its exibilties and rich forming posibilities make me start to think of bringing exibility to porcelain moulding process. But after several tests it was found very hard to nd replacement for plaster for its extraordinary water absorbing ability, So the point comes to the plaster.
