Study on the Influence of Copper Oxide on the Saturation of Porcelain Glaze: A Case Study of Green Cyan Glaze

The science and aesthetics of glaze color represent a unique cultural art form. This study investigates how adjusting the ratio of cyan glaze components and controlling the lattice sintering temperature at approximately 1210 degrees Celsius can produce variations in shades of hill green and forest green cyan glazes on white porcelain test pieces. In Chinese, the term originally refers to green, but it is often used to describe the appearance of mountain scenery from a distance, particularly in gray and rainy weather. In such conditions, the green hues blend into blue, subtly revealing the beautiful scenery of distant mountains. The experimental results regarding glaze lattice formation indicate that test pieces containing talc and calcium carbonate exhibit a greenish tint, while those made with strontium carbonate and barium carbonate display a bluish-green tint. Through the innovative combination of copper oxide minerals and precise control of firing temperature within the medium to high-temperature range, the fusion and transformation of ionic crystals can be achieved, while simultaneously reducing oxygen and energy consumption in the process. This study introduces a novel method of blending minerals to investigate the mechanism behind altering the glaze color recognition threshold. These findings hold academic significance for understanding the impact of alkaline earth metals on green-cyan glaze colors and also present new avenues for future research in the field of glaze coloration.
