Cobalt Tin Alumina Blue Watercolor Ink

Description

Cobalt Tin Alumina Blue Watercolor Ink is our exquisitely hand crafted watercolor ink made with an extremely concentrated, high quality single source pigment. Every bottle is meticulously hand mixed, poured, and sealed, using water, pure local honey, natural gum arabic, a small amount of food grade sodium benzoate preservative, and less than 1% bentonite to slow settling and aid reincorporation. Every ink is single pigment with maximum concentration and no fillers or extenders.

In use, Cobalt Tin Alumina Blue gives a powerful and controlled blue ideal for twilight skies, deep water, architectural shadows, night scenes, florals, and cool passages in figure work. It has strong tinting strength without the overwhelming staining of phthalo blues, making it easier to lift, soften, and refine. It mixes beautifully with cool and warm reds to create complex violets, with earths for deep blue grays and shadow neutrals, and with yellows for subdued, moody greens that stay crisp rather than muddy.
