Abstract

Mimetic Tianmu glaze has been synthesized and analysed by using X-ray diffraction, energy-dispersive X-ray spectroscopy, scanning electron microscopy and transmission electron microscopy. It was found that the main body of the glaze was amorphous aluminium silicate with many embedded polycrystalline spherical particles of metal oxides containing manganese, cobalt, vanadium, bismuth and tungsten. Two dimensional spinel dendrites crystals of manganese, cobalt and aluminium oxide formed on the surface of the glaze. The formation mechanism of the microstructures in the Tianmu glaze is proposed. The colour appearance of the glaze has also been discussed. It has been found that the crystal thickness dependant light interference could be an important factor for the appearance of rainbow-like colour in the glaze layer.
