ABOUT THE PORCELAIN & CERAMIC…
Porcelain is a ceramic material made by heating clay-type materials to high temperatures. It includes clay in the form of kaolinite.The raw materials for porcelain are mixed with water and form a plastic paste. The paste is worked to a required shape before firing in a kiln.
After a first drying step, each porcelain item is cooked 3 times in oven to 980°C (1800°F) and to 1240°C (2260°F) > enameling and waterproof process. Then comes the third low temperature step in order to fix the gilding application.
The first important French soft-paste porcelain (fired to 1240 oC) was made at the Saint-Cloud factory before 1702. Soft-paste factories were established in Chantilly in 1730 and in Mennecy twenty years later. The Vincennes porcelain factory was established in 1740, and moved later to larger premises in Sèvres in 1756. Vincennes soft-paste was whiter and more perfect than any of its French rivals, which put Vincennes/Sèvres porcelain in the leading position in France.
