Glossy Glaze


'Gloss' refers to how shiny and light-reflective a glaze is. Glazes high in glass former (SiO2, B2O3) are glossy. Those high in Al2O3 tend to be matte. Fluid glazes can crystallize to a matte surface if cooled slowly or a glossy surface if cooled quickly. The SiO2:Al2O3 ratio is taken as a general indicator of glaze gloss, ratios of more than 8:1 are likely to be glossy. In some industries, gloss is a more of a product of firing than chemistry. For example, a glaze may normally fire matte (by having a chemistry that crystallizes heavily on cooling, for example), but when super-cooled it will fire glossy.
