Ultra Stains have been selected for being the best quality stains available in the world. Sourced from a number of different manufacturers they are tested to ensure each batch meets a quality standard. Independant laboratory tests are carried out at random on the stains at source to test for lead content and cadmium release.

All the cadmium stains are of the zirconium encapsulated type.  Ball milling of these colours should be avoided to prevent damage to the zirconium layer exposing the cadmium.  Typically these stains only need a few minutes for full dispersion to be achieved.

Instructions for underglaze use:

Ultra Stains can be used for underglaze use, aswell as staining a glaze.  (Check details above or centre of product label for exclusions).  For underglaze use mix 3-4 parts of colour to 1 part 3981 Underglaze Flux and 3974 Underglaze Media until a creamy consistency is achieved.  Thin with water and apply under a transparent glaze or to the dry surface of an opaque glaze (majolica).

Staining a Glaze:

A coloured glaze can be easily produced by adding stain to a trransparent glaze.  This is the way that most earthenware coloured glazes are produced.  The amount of colour added will effect the strength and/or opacity of the glaze.  The normal suggestion is adding between 5-8% of stain to a glaze.

Staining a Decorating Slip

Additions of 10-18% can be made to a White Decorating Slip, but this must be tested.
