Can be used to color clay bodies, slips, or glazes. They can be mixed with water or with frits and brushed onto pottery forms, either over or under a glaze.
Mason stains react differently under different circumstances. Some of the variables that can alter your results include the chemical composition of the clay body and glaze that you use, the firing temperatures, the kiln atmosphere and the concentration of stain that you use. You will need to experiment a bit with your particular applications.
Maximum Firing limit 2300°F (1260°C)
