Changhua Tian Huangshi identification criteria:
1. It is necessary to determine whether the mineral composition is composed of dikai stone and kaolinite by infrared spectrum analysis and X-ray polycrystal diffraction. This is the standard for identifying the composition of Changhua Tianhuang Yellowstone minerals, that is, Changhua The mineral composition of Tian Huangshi must be dikai or kaolinite or dickite and kaolinite transition minerals, but the stamp stone composed of dikai or kaolinite is not necessarily Changhua Tianhuang.
