Art Nouveau Pink Marble Cassolette Candlestick Holders. Round base with a central column that supports a circular saucer. Cassolettes were vases or containers (perfume burners) which were placed on the upper edge of the fireplace mantel in pairs or one on each side next to a clock or a pendulum clock (we also suggest the bookend function). Were very often made of precious metal, bronze or precious marble. This pair belongs to this last category, in fact it is composed of a rare types of Italian marble. Art Nouveau style flowers in the bronze. Very heavy- 3 pounds each.
