Ceramic stains are not meant for all firing conditions and are generally designed for neutral or oxidation firing atmospheres (although some may work in reduction atmospheres). Because ceramic stains contain coloring metal oxides along with other ceramics materials like opacifiers, silica, and alumina, adding them to certain glaze bases can cause a glossy glaze surface to turn matte. Ceramic stains are generally added at 5–8% in a glaze and 15–25% in slips and clay bodies. At 8% most of the glazes are opaque and flat but if you add smaller amounts of stain (1–3%) it is possible to get transparent colors, including some very nice transparent celadon-colored glazes, when fired in an electric kiln or similar neutral atmosphere.
