Mason is one of the leading stain manufacturers in the United
States. We carry a wide variety of the Mason color line. They are
extremely versatile, give color to glazes, slips, and clay bodies.
Most can be used at any temperature.
(Note, unless
you are experimenting with unusual techniques, do not attempt to
simply brush on stains mixed with water. They need to be fixed
in a medium such as a slip or glaze which can then be brushed on.)
In the past, stable red stains at high firing temperatures were
unknown to the ceramic industry. This gap was bridged by
Degussa's line of inclusion pigments which are stable up to a firing
temperature of 2372F (1300C) and which are resistant to unfavorable
kiln atmospheres.
By using inclusion pigments in glazes, the
following additional advantages can be achieved in comparison to the
traditional cadmium glazes:
Favorable thermal expansion,
Low
sensitivity to contamination during processing,
Low influence of
contamination in the bisque,
Possibility of blending with other
stains, oxides and frits,
Compatibility with other glazes,
Matting
possibility with the addition of zinc oxide,
Non-problematic
behavior during processing of glaze slurry/slip.
