Painter, op. 1754 - 1803.
Tandart was a fan painter before entering the Vincennes factory on 21 April 1754. He chiefly specialized in flowers which he painted in sprays, bouquets, wreaths and garlands, various border patterns, baskets, garden landscapes and monograms. Some of his work was in monochrome, he occasionally retouched the work of other painters, and he worked on both hard and soft paste. Besides tea services and useful wares, he decorated a number of large furniture plaques and a number of vases to which he often added floral decoration in minor reserves.
He contributed to the Madame du Barry service of 1769, the Catherine II service, and the services ‘de la Reine’ of 1781 and 1784. He also retouched a large cup painted by Cornaille for the dairy of Marie-Antoinette at Rambouillet.
He was the elder brother of Charles Tandart, also a painter at Sèvres, op. 1755-60. He married Catherine-Josèphe Prisette in 1757.
