"Azo Pozzolana Pigment"

An azo dye produced via the 'grind method ' ( 5deg.C/ 5 minutes/ mortar & pestle) was diluted with water and meta-kaolin added. The mixture is stirred well and water allowed to evaporate overnight in a fume hood.
A gouache paint can be formulated if minimal water, high-fructose corn syrup ( binder) and a drop of PEG 8000 is added.
If an acrylic paint formulation is desired, no high fructose corn syrup is added ( the acrylic is the binder) , and minimal water and clear acrylic emulsion added. The paint is stirred well and kept in an air tight vial until needed.
