This paper describes methods of coloring glass layers formed on the surface of a cement composite by laser irradiation. We found that blue and green coloured glass layers are obtained easily by the addition of Co-base and Cr-base pigments to mortar whereas yellow and pink are difficult to obtain.This is because glass formation temperatures are higher than yellow and pink color formation temperatures and, in addition, the constituents of cement and aggregate tend to obstruct coloring. To obtain luster colours, we found necessary to add a transparent glaze to the mortar composition. The addition of glaze lowers glass formation temperatures and reduces the relative Volume of cement and aggregate. The relative ease of obtaining blue and green colors compared to yellow and pink is explained by considering the mechanisms of color formation.
