A type of ware obtained by mixing clays of various colours to imitate natural marble or agate. Marbled pottery is found at least as far back as the 1st century AD in Rome. Called Jiaotai (=twisted body), marbled wares became a frequent type in Tang dynasty pottery in China. The production seems to have started in Gongxian kiln in Henan, from where it spread to Xiuwu (Diangyangyu kiln) and Jiaozhuo (Xiwangceng kiln) in northern Henan. The ware was continued throughout the Chinese history into today.
