  • 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.

  • It is believed that cobalt ores had been widely exploited in West Asia for use as pigments since as early as 2000 B.C. In China, they were first used for glassmaking during the Warring States (475-221 B.C.) period.
