The Nast factory is a hard paste porcelain factory founded in 1784 in Paris by Jean Népomucène Hermann Nast, an Austrian emigrant naturalized French. Arrived in 1778 from the Palatinate, Nast took over in 1783 a porcelain factory installed on rue Popincourt. The following year, he transferred it to 70 rue des Amandiers-Popincourt. He inaugurated a new technique of applying gold with a scroll wheel for relief decorations, which he patented in 1810. He also developed new colors such as chrome green, called Empire green, created with the chemist Louis. -Nicolas Vauquelin, who supports very high cooking temperatures. The Nast factory supplies French high society and several European courts. In 1814, she created one of the oldest porcelain services in the White House. After the death of Jean Népomucène Hermann Nast on March 15, 1817, the company remained in the hands of his two sons Henri Jean and François Jean, associated with their father from 1811. Visiting the exhibition of 1819, King Louis XVIII awarded them his praise: "I am pleased to see talent passing from father to son, and I urge you to cultivate it".
