Ceramic
Art of making pottery, based on the property of clay to give, with water, a plastic paste, easy to shape, becoming hard, solid and unalterable after cooking.
Chamotte
Fine refractory earth particles incorporated into the earth allowing better resistance to thermal shocks and to facilitate drying.
Sandstone
Ceramic fired at a very high temperature giving the sculpture a great resistance, especially of the gel.
Raku
Low temperature sandstone cooking process. (Invented in 1580 in Kyoto, the pottery thus made was intended for the tea ceremony. They are characterized by very deep glazes, thick and riddled with small depressions).
15th century Asian sandstone cooking technique, which consists of cooking the sculpture until the enamel melts (1000°C) and then extracting it from the oven at high temperature, provoking a great thermal shock. The sculpture is then "smoky", covered with sawdust of wood that ignites on contact with the incandescent room. The smoke, when burning, will reveal a particular cracking on the enamelled parts.
