He was one most important painters of flowers and fruit on porcelain in the first half of the 19th century. His delicate brush strokes, color, and finesse were unsurpassed. From 1800 to 1843, Nigg was lead flower painter at the Vienna porcelain factory. In 1835 he began holding classes in painting at the factory. During the Biedermeier Era, flower painting became immensely popular including painting on porcelain. At the The Great Exhibition of 1851 in London, Nigg presented a thirty inch tall painting on porcelain on behalf of the Viennese factory. Examples of his works are found in the Hermitage in St. Petersburg as well as other museums and important collections.
