Imperial Privilege: Vienna Porcelain of Du Paquier, 1718-44:Black monochrome decoration called Schwarzlot is a signature feature of Du Paquier porcelain. It reflects the Baroque fondness for austere, understated grandeur. On this charger, the Schwarzlot was subtly highlighted with gold, making it extraordinarily luxurious. The artist’s use of a quill pen to draw fine lines and hatchings imitates copperplate engravings. The technique is associated with Jakob Helchis, a gifted employee of the manufactory.
