This comprehensive exhibit traces the complex history of porcelain, from its ninth-century origins in China to the 18th century, when Europeans finally unraveled the mystery of porcelain production and factories sprang up in Saxony, Vienna, Russia and France. Visitors will peruse more than 125 objects from the late heiress Marjorie Merriweather Post’s holdings, from vases and teapots to figurines and dishes, along with examples of modern-day designs.
