Stain (pinks)

Pinks/Crimsons (CrAl, CrAlZn)

Chrome-alumina pinks have metameric properties, making a shade appear different under different light conditions. It is therefore very difficult to obtain precise matchings with other types of pinks for identical shades under both natural and artificial illumination.

Color Range
-----------
Chrome-alumina can produce a color range of peach through pink to bluish pink.

Stability/Kiln Atmosphere
-------------------------
Excellent at firing temperatures up to 1300C with glazes having a high content of zinc oxide and alumina and a low content of lime. Should be fired in an oxidizing atmosphere.

Compatibility
-------------
Suitable for blending with all types of zircon based colors, tin-vanadium yellows and chrome browns. Blends with zircon-vanadium blues tend to produce shades of grey.

Cost
----
Relatively low.

Note: This description is taken from information provided by Blythe Matthey and may or may not apply to stains of this family from other companies.

Chrome alumina colors are widely used as pink and pink-grey shades in the manufacture of glazed ceramic tiles fired in an oxidizing atmosphere to 1300C. For optimum color development and good surface finish, the glaze should have a high content of zinc oxide and alumina and a low lime content.
Not recommended as a body stain or underglaze color.
