The Nast factory is a 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 dial for embossed decorations, for which he filed a patent in 1810 he also developed new colors such as chrome green called Empire green, created with the chemist Louis- Nicolas Vauquelin, who withstands very high cooking temperatures. The manufacture of Nast 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 1819 exhibition, King Louis XVIII awarded them his praise: "I see with pleasure the talent passing from father to son, and I urge you to cultivate it".
