The flourishing of the Silk Road trade route saw imported cobalt introduced to China and its application, with other lead-based glazes, on low-fired earthenware, leading to the rapid development of three-coloured sancai wares. The Samarra Blue (sumali qing) or Sumatra Blue (suboni qing) cobalt used for Yuan wares was rich in iron, which yielded a glaze with darker blue spots. This so-called heaped and piledeffects was caused by the accumulation of iron oxide in the cobalt pigment in certain areas of the surface.
