Spectrum's 1050 Underglaze Base is formulated as a base media for preparing your own underglaze colors similar to the 500 series Underglazes. This base has some frit in it, which acts as a flux to help the stain be a compatible fit with either greenware or bisque. It also has various additives which keep the frit and stain suspended and makes it brush on smooth and easy. It is lead free, non-toxic, and dinnerware safe when covered by a dinnerware safe clear glaze. In order to achieve an underglaze of a strength similar to the 500 series Underglazes, it is recommended that you mix 1 part of dry powder ceramic stain to 2 parts wet Underglaze Base by weight. For example, if you put half a pint (8oz or 228gm) of 1050 Underglaze Base in a container, you should mix 114gms of stain with the base. This is only a GENERAL guideline as the strengths of differnet color stains vary and you should test your colors, particularly the first time you mix them to determine the correct strength for your application needs. Be sure to test if firing to Cone 10! This will flux much more at this temperature.
