Firing Process and Factors Affecting the Copper-Based Green Glaze of Jun Porcelain in Industrial Ceramic Production

Abstract

The preparation of copper green glaze was conducted using a combination of raw materials, including kaolin, feldspar, calcite, talc, limestone, quartz, and copper oxide. The influence of formulation composition and preparation process on the surface of green glaze was examined through the application of single-factor and orthogonal experimental design methodologies. The single factor experimental method entailed a systematic alteration of a single factor, such as the proportion of raw materials, firing temperature, or firing time, to examine its individual impact on the surface of the green glaze. In contrast, an orthogonal experimental design simultaneously considers multiple factors and assesses their relative importance for the glaze effect. The objective of this study is to optimize the formulation composition and preparation process of copper green glaze in order to achieve the desired surface effect and to improve the efficiency and quality of glazes in industrial manufacturing applications.
