New Longquan Celadon Technology to Reduce Environmental Pollution

Abstract

In this article, full use of clay materials in the processing of Longquan celadon clay is presented. The microstructure and chemical compositions of the Longquan celadon samples were characterized by an x-ray fluorescence spectrometer, x-ray diffraction, and scanning electron microscope/electronic differential system analysis. The results showed that Longquan celadon has high SiO2 and Al2O3 contents, resulting in better transparency and gloss compared with other celadon types. The structure scattering and chemical coloring of Fe2O3 also affected the color characteristics of the glaze surface including the opacity and color saturation. We observed an increase in the blue tone of the Longquan celadon, attributed to several factors including the phase separation of the droplets to form structural color by Rayleigh scattering and amorphous photons. We made full use of clay raw materials to produce Longquan celadon and compared it with the traditional method, thereby disposing of the tailing waste and reducing the environmental pollution resulting from it.
