Mason Stains ®(by Mason Color Works)

Mason Stains ® (by Mason Color Works)- Mason Stains are combinations of oxides, fritted to insure uniformity of color and thus insure uniformity of results in firing. They can be used to color transparent or opaque glazes, slips, engobes or clay bodies. The stains may also be used effectively as colorants for direct brush decoration when mixed with water and a flux. More flux is required at the lower temperatures to melt the stain. Color results will vary according to glaze composition, firing temperature and kiln atmosphere. The quantity of stain used will vary between 1%-15% depending on the depth of color required. Most of the stains will produce the color indicated and remain stable up to 2300F in both oxidation and reduction atmospheres. Some of the colors such as pink, yellow and purple can be volatile at higher temperatures, and in reduction atmospheres. Testing is recommended to determine stability. Calcium oxide may affect the color of many stains. For best color development, calcium carbonate (whiting) should be added to the base glaze where indicated. See reference chart for details. As zinc is chemically combined in some of the stains, free zinc can alter or destroy the intended color. Again, for the very best color results, follow the guidelines of the code numbers listed next to the stains. Pastel colors can be produced by adding tin or zircon opacifiers in small amounts or by using mason extenders. Stains may be combined to produce new colors. Testing is necessary. *Flux - Ferro Frit 3124 can be used as a flux to mix with the stains. 85 stain/15 flux is a good starting point for testing.
