Workers produce "black pottery" at a studio in Yingjing County, Southwest China’s Sichuan Province. The silvery-grey vessels, fired in a traditional kiln, are made from special clay found in Yingjing county that is mixed with local coal ash. Dubbed "black pottery", the craft was included in the list of national intangible cultural heritage items in 2008. (Photo: China News Service/Li Guobin)
