Laser Glazed Color Surface on Whiteware

Traditional procedure of firing glaze is usually time consuming, energy costly and not environmental friendly. This paper reports the result of laser glazing on whiteware, and compares the glossiness and chromaticity of the glazed color surfaces by using a spectrophotometer. The cobalt blue and cobalt black color glaze surfaces are prepared by either traditional firing or laser glazing. Study shows that laser glazing is practicable, the resultant color glaze surface has better glossiness but the chromaticity is slightly weaker than that processed by traditional firing. The method of laser glazing is simple, can save energy, and worth to study further.
