Mason Stains

About Mason Stains
Mason Stains are calcined colorant oxide blends used to give color to glazes, stains, overglazes, slips, engobes, porcelain clays and other ceramic materials. Mason Stains are uniform colorants produced to exacting standards and are processed in such a way that they are much less toxic than the component oxides. Mason Stains give true bright reproducible colors, are concentrated, are uniform at a variety of temperature ranges and have little effect on the base glaze’s performance, other than color.
Mason stains are stable to around cone 5-6 and some will fire as high as cone 9. Best color response in some Mason Stains is achieved in glazes with at least 15% calcium, and most colors are brightest at low temperature.
Mason publishes a color chart which shows each stain in a glaze at an indicated concentration. The use of the chart is often helpful in formulating glazes. All good glazes require testing to provide satisfactory results.
WARNING: WHILE MASON STAINS ARE SAFER THAN USING RAW OXIDES AS COLORANTS, THEY PRESENT HAZARDS IN THE RAW STATE AND MAY BE SUBJECT TO LEACHING IN THE FINISHED GLAZE.
