Crimson (6003) by Mason
Mason Stains can be used to color transparent or opaque glazes, underglazes or slips.
The quantity of stain used will vary between 1%-15% depending on the intensity of color desired. Most of the stains will produce the color indicated and remain stable up to 2300°F in both oxidation and reduction atmospheres.
We also carry pints of underglaze base for mixing.
