Clignancourt porcelain

Clignancourt porcelain, also "Porcelaine de Monsieur", was a type of French hard-paste porcelain, established by Deruelle in January 1775 at Rue de Clignancourt, Paris. Soon after, the manufacturing patent was transferred to Monsieur, the King's brother, and future Louis XVIII. The porcelain was then called Porcelaine de Monsieur.
