This large jar has the distinctive brown and ivory glazed decoration that was produced during the Ly dynasty (1009-1225) using the techniques of carving. This was known as sgraffito. The carved designs were then painted with underglaze iron-brown while the background was covered with an ivory glaze. Some scholars suggest that such two-colour wares were inspired by the tonal contrasts of Chinese Cizhou wares. However, the inlay decoration technique used by Vietnamese potters is not found among Chinese wares during the same period. Hence, innovative art styles of this period can be considered expressions of a renewed sense of cultural identity, which emphasised artistic distinctiveness from Chinese traditions.
