Nymphenburg is famous for the lifelike depiction of its animal figures, especially those painted in underglaze. This technique was introduced at the manufactory in 1903 and reached its peak during the Art Nouveau period. In this technique, the color is applied to the unglazed porcelain in various layers by airbrush before the second firing. The porcelain painters use fine tools to bring out details of fur and plumage, as well as characteristics of facial expressions. Brilliance and depth are added to each piece by the final applied glaze. To this day, underglaze painting is carried out to the highest degree of perfection by the Nymphenburg artisans, especially on animal sculptures and figures.
