Just six miles north of Cardiff, Nantgarw China Works & Museum is one of the most important industrial heritage sites in Wales, a nationally significant museum, a historically renowned porcelain factory, and a thriving centre for contemporary ceramics.Between 1813 and 1820 William Billingsley created at Nantgarw the finest porcelain ever made. The incredibly fine, white and translucent porcelain was decorated by the finest experts of the age for royalty and aristocracy. However, a commercially crippling loss rate in the bottle kilns resulted in production lasting only four years. The porcelain is now extremely rare and valuable. When porcelain production finished the factory continued as a pottery and from 1833 until 1920 under the Pardoe family produced earthenware flower pots, teapots, stoneware bottles and up to 10,000 clay smoking pipes a week. In 2018, after a major research project led by Nantgarw China Works, Billingsley's lost original recipe was rediscovered and the factory is once again producing the legendary porcelain.
