These artist grade watercolors continue the Blockx family legacy that began in 1865. They are made using the same processes developed many years ago. Pigments are mixed with only the finest quality ingredients, including the purest gum arabic and honey.
Color Swatches created using heavy application/diluted application and were applied on cold press watercolor paper (150 lb) material.
Oxides of Cobalt and Chromium
Cobalt Chromite Blue is an opaque pigment with moderately low tinting strength.
Cobalt salts have excellent lightfastness and temperature stability.
Cobalt salts are toxic when ingested or inhaled, and slightly toxic on contact with the skin. Evidence of Chromium(III) carcinogenicity is inconclusive. Chromium(III) salts appear in greenish pigments.
