Pigment Information
This color contains the following pigments:
PB28-Cobalt Blue
PB36-Cobalt Chromite Blue Green Spinel
PW4-Zinc White
Pigment Name
PB28-Cobalt Blue
Pigment Type
inorganic
Chemical Name
cobalt(II) oxide + aluminum oxide
Chemical Formula
CoO + Al2O3
Properties
Cobalt blue is a semitransparent pigment with low to moderate tinting strength. When it dries, it appears lighter and less saturated. Pigment particles are large and grainy. Differences in how the pigment is ground and mixed lead to considerable differences in its performance among various manufacturers.
Permanence
Cobalt blue is absolutely lightfast and extraordinarily stable. The stability of cobalt salts at high temperatures make them the standard for blues used in ceramics and glassware.
Toxicity
Cobalt salts are toxic. Avoid respiratory and skin contact. Soluble cobalt may cause irritation and allergic reaction through contact with skin. It is considered a possible carcinogen.
History
Since ancient times, smalt blue has been used to color glass and ceramics. Cobalt salts, which give smalt its characteristic blue color, were identified in the 18th century. Techniques for manufacturing Cobalt Blue, a chemically pure salt of cobalt and aluminum oxide, were developed in 1802.
Pigment Name
PB36-Cobalt Chromite Blue Green Spinel
Pigment Type
inorganic
Chemical Name
Oxides of Cobalt and Chromium
Chemical Formula
Co(Al,Cr)2O4
Properties
Cobalt Chromite Blue is an opaque pigment with moderately low tinting strength.
Permanence
Cobalt salts have excellent lightfastness and temperature stability.
Toxicity
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.
Pigment Name
PW4-Zinc White
Pigment Type
inorganic
Chemical Name
zinc(II)-oxide
Chemical Formula
ZnO
Properties
Zinc White is the coolest white, and it has a cold, clean masstone and a slightly bluish tint. It has less hiding power and is more transparent than other whites. It dries slowly and is good for painting wet into wet and for glazing and scumbling. Zinc White is neither as opaque nor as heavy as Lead White, its covering power is not as good, and it takes much longer to dry. However, it does not blacken when exposed to sulfur in the air as Lead White does. It is very valuable for making tints with other colors. Unmixed Zinc White dries to a brittle and dry paint film that may crack over the years, so it is not good for frescoing. It is more transparent in acrylic form than Titanium White and is the most commonly used white with gouache. Chinese White is a version of Zinc White appropriate for opaque watercolor techniques.
Permanence
Zinc White has great permanence and lightfastness.
Toxicity
Zinc White is moderately toxic if ingested and slightly toxic if inhaled.
History
Though historians are divided on who first isolated the element zinc, they agree that it was first suggested as a white pigment in 1782. Zinc White was accepted as a watercolor in 1834 and was called Chinese White due to the popularity of oriental porcelain in Europe at the time. Ten years later, a suitable oil form was produced. By the early 20th century, it had improved to the point where it was an acceptable alternative to Flake White.
