The Glossiness and Chromaticity of Laser Glazed Color Glaze

Abstract

With the improvement of people's living standard, customer-to-design in small lots or even single piece production will become a trend to produce high-grade ceramic decorations in future. However, the traditional method for firing color glaze is not suitable for this change. Hence to search a convenient and effective method of firing color glaze has become significant. This paper reports the result of color glaze glazed on white ceramics by laser, and compares the glossiness and chromaticity of the color glaze surfaces by using a spectrophotometer. The cobalt blue and cobalt black color glaze surfaces are prepared by both traditional firing and laser glazing. Study shows that laser glazing is feasible, the resultant color glaze surface has better glossiness but the chromaticity is slightly weaker than that of sample processed by traditional firing. The method of laser glazing is simple, can save energy, and worth to study further.
