Abstract: Although there have been several red pigments, the preparation of red pigments is a challenge. Gold ruby pigment is an overglaze pigment with gold colloid as the coloring agent. It has a wide range of colors, such as brown, pink, yellow, purple and so on. Its bright colors and strong tinting power make it one of the precious decorative pigments on ceramic glazes. In this article, the research status of gold ruby pigment and coloration mechanism will be summarized and the effects of the factors such as preparation process, composition, morphology and size of the colored particles on the effective ness of coloration. Finally, the application status of gold ruby pigments was prospected.
Key words: gold ruby pigment; research status; coloration mechanism
