Abstract

The purpose of this study is to investigate the coloration characteristics by identifying the factor affecting red coloration of copper red glaze in traditional Korean ceramics. This study analyzed the characteristics of the reduction-fired copper red glaze by using XRD, Raman spectroscopy, EDX and UV-vis spectroscopy. As a result of XRD analysis, the glaze completely melted and amorphous glass appeared overall, and the characteristic peak of metal Cu was shown together. In addition, as a result of Raman analysis, the characteristic bands of CuO and $Cu_2O$ were shown together. The distribution of component elements was observed by EDX. As a result, copper(Cu) were distributed throughout the glaze. Thus, it was shown that copper red glaze appeared the best red coloration because metal Cu, CuO and $Cu_2O$ evenly existed throughout glaze in particle colloidal state. The chroma value of the copper red glaze was CIE $L^*$ 30.07, $a^*$ 13.65, $b^*$ 3.72. Wine-Red Solution was shown by Dark Graish Red coloration.
