    Bell-shaped cup with blue glaze

    This bell-shaped porcelain cup demonstrates the Jingdezhen potters’ use of a high-fired monochrome glaze. The cup is covered with a deep, blue glaze coloured by powdered cobalt oxide. It was given one high-temperature firing to fix the colour and the underglaze blue reign mark on the base. The cup's form is innovative to the mid-sixteenth century and was also used for contempory white, yellow and blue-and-white porcelains.
