Porcelaine de Paris
Since the discovery of kaolin, needed material for the making of porcelain, porcelain factories also called porcelain manufactures are on the increase in all France and naturally in Paris. Most of those manufactures worked in the 18th century under the protection of a member of the Royal family, such the comte de Provence, future Louis XVIII, who protected the Clignancourt manufacture. But during the 18th and 19th century, numerous pieces did bear no making mark. It was then almost imposssible to attribute them to any particular Parisian factory, hence the expression “Paris porcelain” or “Vieux Paris” including all those various productions.
