Goblets decorated with the "Leliwa" coat of arms are connected with the 18th-century owners of Wilanów. In 1720, Elżbieta z Lubomirskich purchased the Wilanów estate from crown prince Konstanty Sobieski. At that time, Poland's first magnate-owned crystal glass factory was already in operation in the district of Lubaczów, owned by her husband, Grand Crown Hetman Adam Mikołaj Sieniawski (1666-1726). In 1717, work began in the factory to launch a line of luxury glass products (including candelabra) to match the quality of the royal glass works in Bielany near Warsaw and other renowned European centres. To realize this ambition, foreign production specialists were employed in the early period. Fortunately preserved in the Wilanów collection, these excellent early products show that Sieniawski achieved his goal. The fragile output of the crystal glass works is very scantily represented in modern Polish collections. The two "carp scales" polished goblets and three faceted ones in the Wilanów collection suggests that they were originally part of two large sets of identically decorated vessels.
