A set of porcelain wares on display at Duan Zhenmin's workshop in Mingfangyuan porcelain industrial park in Jingdezhen, East China's Jiangxi province, Dec 22, 2015. A new microwave kiln invented by Duan and his partner made quite a stir at the 2015 International Ceramic Expo in Jingdezhen. The new kiln improves efficiency and saves energy. It cuts the firing time for porcelain wares to no more than two hours, compared to seven hours, potentially changing the production model of the industry. [Photo by Liu Xuanyi/chinadaily.com.cn]
