These stains are for adding into clay, using as washes, adding into glazes or into decorating slips or creating underglazes - see typical underglaze recipe below.Stains give a more predictable colour than using oxides especially at lower temperatures.
All go to 1250oC - GS1, 6, 7, 24, 26, 27 should work well up to 1300oC.
If trying to make a powder underglaze a typical recipe is 52% stain, 22% glaze powder, 22% Quartz 600, 4% FS200 Flux or 1% Lithium; Or for a strong stain such as the dark blues, typically 25% stain, 22% glaze powder, 49% Quartz 600, 4% FS200 Flux or 1% Lithium. Then mixed with UGM/water at an equal weight to make a liquid. This is a rough guide only, you must test them yourself.
When mixing stains into clays or decorating slips they will obviously become a pastel shade.
We list the original oxides used in the manufacture of the stains before the material is made safe by melting, sintered and ground down.
The pictures show 7% in the glaze powder, 10% in the glaze powder and 13% in the glaze powder which was then mixed with water before applying.
