Valuable pair of cups without brand name but due to the physical characteristics and decoration of the production of Claudius du Paquier, founder in 1718 of the Vienna porcelain factory, the second to be opened in Europe. The refined floral motif is of the type called Holzschnittblumen, characterized by large flowers, derived from the prints of botanical treatises, widely used in the very first production of European porcelain. Porcelain is a ceramic product based on kaolin, a particular type of light clay, and finely ground minerals such as quartz and feldspar, which when cooked at high temperatures becomes a material of great beauty, translucent white with a hard and compact texture. Born in China in the eighth and ninth centuries AD, porcelain began to be imported into Europe only in the fifteenth century. Numerous attempts were made to reproduce it immediately, but only at the beginning of the eighteenth century did the alchemist Johann Friedrich Böttger discover its secret, setting up the first European factory in Meissen, near Dresden. The formula for the production of porcelain was jealously guarded by Meissen and Claudius du Paquier took advantage of his position as military adviser to the Austrian imperial court to get hold of the secret and to approach and recruit Meissen artisans. In 1718 it was thus possible to open the first porcelain factory in Austria, located near Vienna.
