Crystal&Powder: Cobalt Oxide
Palm's cobalt oxide is the principle source of CoO used in glazes, glass and enamels. It is a coloring oxide that produces blue in glazes at all temperatures.
Palm's cobalt oxide is ideal for enamel frit applications. Frit is a homogenous melted mixture of inorganic materials that is used in enameling iron and steel and in glazing porcelain and pottery. Frit renders soluble and hazardous compounds inert by combining them with silica and other oxides. Frit also is used in bonding grinding wheels, to lower vitrification temperatures, and as a lubricant in steel casting and metal extrusion.
