Please note the description in the printed and e-catalogue should read:
A PAIR OF SEVRES PORCELAIN BLEU CELESTE FOOD WARMERS AND COVERS
CIRCA 1769, BLUE AND YELLOW INTERLACED L’S ENCLOSING THE DATE LETTER OF A LOWER-CASE Q, PAINTER'S MARK FOR JEAN-JACQUES PIERRE
The present bowls and covers were designed to keep food warm, their form based on that of an ice pail and adapted from a Vincennes veilleuse, hot water beneath the liner replacing the open flame used as a heat source in the earlier version. For a Vincennes example with a warming bowl, stand to house the flame of a small lamp, and a cover of the same form as the present examples, see Christie’s Paris, sale 5605, 17 May 2010, lot 106. The current form likely required liners.
