Since 1996, in addition to painting, we have expanded to the manufacturing of porcelain and now the majority of our products are produced here.
Porcelain, like all classic ceramic products is made up of three materials: kaolin (China clay), quartz and feldspar. When mixed with water, kaolin becomes malleable, easy to shape; objects worked of kaolin preserve their shapes even after drying and firing. Feldspar helps the material pack during firing, as it starts softening as low as 1100°C due to its high alkali-oxide contents. The role of quartz is twofold: on the one hand it contributes to translucency, on the other; it significantly influences the stability of ceramics during firing.
Porcelain is produced through casting. The preparation of liquid paste starts with dispensing all the basic materials and homogenisation. Then the paste is put into a mixing container where it is constantly stirred with a low speed revolving spiral agitator for about 4-6 days, in order to evacuate the air pockets.
For casting we use plaster mould. Plaster is the most important auxiliary material of ceramics production. If mixed with water plaster powder has the particularity of making a paste that may be easily molded, and hardens in relatively short time. Still, after hardening, it is quite easy to carve it, and after becoming completely hard, it is also solid enough to withstand the physical stress during shaping and transportation.
In addition, due to its porosity the plaster sucks out the water from the clay. The plaster mould allows the same size and pattern for the serial production of ceramic ware.
