The purpose of this study is to investigate the coloration characteristics by identifying the factor affecting redcoloration of copper red glaze in traditional Korean ceramics. This study analyzed the characteristics of the reduction-firedcopper red glaze by using XRD, Raman spectroscopy, EDX and UV-vis spectroscopy. As a result of XRD analysis, the glazecompletely melted and amorphous glass appeared overall, and the characteristic peak of metal Cu was shown together. Inaddition, as a result of Raman analysis, the characteristic bands of CuO and Cu2O were shown together. The distribution ofcomponent elements was observed by EDX. As a result, copper(Cu) were distributed throughout the glaze. Thus, it was shownthat copper red glaze appeared the best red coloration because metal Cu, CuO and Cu2O evenly existed throughout glaze inparticle colloidal state. The chroma value of the copper red glaze was CIE L* 30.07, a* 13.65, b* 3.72. Wine-Red Solutionwas shown by Dark Graish Red coloration.
