A bamboo and bamboo veneer 'kui-dragon' snuff bottle, 6 cm high. Provenance: Singapore private collection. Bamboo veneer (tiehuang) literally 'pasted yellow', sometimes also known as zhuhuang ('bamboo yellow') is made by stripping and flattening the thin inner lining of the cortex. It is a distinctively less grainy material than the outer skin of the cortex, and usually of a paler colour. It is an art form that was possibly developed in Jiangxi province, although once the art form was developed, it could also have been employed anyplace that enjoyed a plentiful supply of bamboo and a little technical know-how
