Corrosion behavior of tubular crystal on opaque glaze celadon from the Tang Dynasty Qiong kiln site in Sichuan
摘要
The surface of Qiong kiln opaque glaze celadon exhibits a phenomenon of hole corrosion. Using scanning electron microscopy, energy spectrometry, Raman spectroscopy, and other analytical means to conduct the analysis, the results show that this pore corrosion is induced in the tubular crystal, formed by various corrosion behaviors combined with effect formation. The tubular structure constitutes a channel connecting the external environment with the interior of the glaze layer. At the same time, the surface adsorption and ion exchange properties of the tubular structure itself may increase the rate of glaze corrosion.
