The Vincennes porcelain manufactory was established in 1740 in the disused royal Château de Vincennes, in Vincennes, east of Paris, which was from the start the main market for its wares. History The entrepreneur in charge at first, Claude-Humbert Gérin, established workshops and employed craftsmen from the Chantilly manufactory, whose patron, the duc de Bourbon, had recently died. Notable defectors from Chantilly were the debt-ridden brothers Gilles and Robert Dubois, one a sculptor, the other a painter. When early trial pieces were shown to the marquis du Châtelet, he arranged with Orry de Fulvy, brother of a superintendent of royal buildings, that a factory be set up in the premises of the disused royal château to manufacture a brilliantly white soft-paste porcelain. The Chinese manufacturing secrets for porcelain manufacturing were revealed by the Jesuit Father Francois Xavier d'Entrecolles in 1712, and openly published in 1735. One ingredient for porcelain was kaolin; the porcelain manufactory of Meißen, near Dresden, was taking advantage of the first kaolin deposits identified in Europe, but hard-paste porcelain in France had to wait for the first French kaolin, discovered near Limoges later in the eighteenth century. Early experiments produced so many imperfect pieces spoiled in the kiln, that debts mounted, in spite of aristocratic encouragement, and the partners, on the verge of bankruptcy, slipped away, leaving the kilns, workmen and the still-born production in the hands of a subordinate, Louis-François Gravant (died 1765). The continued patronage by Orry de Fulvy achieved the first successes on the Paris market about 1745, and further essential capitalization was raised through a consortium of twenty-one progressive-minded tax farmers. The first direct royal support came in the form of a privilege for manufacturing porcelain after the manner of Saxony (Meissen porcelain), signed by Louis XV, 24 July 1745, in favour of Charles Adam, one of the silent partners. The silversmith Jean-Claude Duplessis was brought in during 1745; he designed vases for Vincennes embodying the robust yet balanced French Rococo. Aside from tea wares and dinner services, and decorative vases, often in imitation of Meißen porcelain— "in the style of Saxony, painted and gilded and depicting human figures" the warrant granted by Louis XV ran— the Vincennes manufactory specialized in making naturalistic flowers, which were incorporated into bouquets or in flower sprays added to cut-glass-hung gilt-bronze chandeliers under the direction of Parisian marchands-merciers, who alone were permitted to combine the production of
