Color Swatch created using Heavy application/medium application/50% tint and was applied on Acrylic Primed Canvas (7 oz) material.
This color contains the following pigments:
PY35:1—Cadmium-Barium Yellow
Pigment Type
inorganic
Chemical Name
cadmium zinc lithopone
Chemical Formula
CdSZn + BaSO4
Properties
Cadmium Yellow is brilliant, dense, and opaque, with good tinting strength and very high hiding power. It is the artist’s principal bright yellow and is available in light, medium, and dark shades. The deeper shades appear deep orange and have the greatest tinting strength. It is slow-drying in oil form and is used in both oil and watercolor form. It cannot be mixed with copper-based pigments. A clean Cadmium Orange is created when Cadmium Yellow is mixed with Cadmium Red. Hues vary by brand. Cadmium pigments have been partially replaced by azo pigments, which are similar in lightfastness to the cadmium colors, cheaper, and non-toxic.
Cadmium Yellow PY35:1 shares the properties of Cadmium Yellow PY35, except that it has lower tinting strength.
Permanence
Cadmium zinc lithopone has excellent lightfastness. It shares the permanence of pure cadmium zinc sulfide (Cadmium Yellow PY35). All cadmium pigments have limited weather resistance, and are unsuitable for outdoor applications.
Toxicity
Cadmium Yellow is a known human carcinogen. It is extremely toxic if inhaled and slightly toxic if ingested. Barium sulfate is extremely insoluble in water, and thus is not biologically active. It is used medically as a contrast medium in radiological procedures.
History
Cadmium Yellow PY35:1 is cadmium yellow pigment that contains 15% or more barium sulfate. It is used to create a less expensive alternative to PY35.
Alternate Names
Cadmium Yellow, Cadmium Yellow Light
PW6:1—Buff Titanium
Pigment Type
inorganic
Chemical Name
titanium di-oxide
Chemical Formula
TiO2
Properties
Buff Titanium is an warm, reddish, off-white pigment that shares the properties of Titanium White, including opacity and slow drying time.
Permanence
Buff Titanium is lightfast and permanant.
Toxicity
Titanium dioxide and iron oxide are naturally occuring and are abundant in the Earth's crust. Both are considered non-toxic. Particle sizes tend to be larger in Unbleached Titanium than for titanium dioxide pigments used in white paints.
History
Titanium dioxide often occurs in nature with iron oxide. Buff or unbleached titanium is a natural mineral form of titanium dioxide. A variety of processes are used to produce buff or unbleached titanium. Some manufacturers may add synthetic iron oxides to a titanium base, while others use naturally occuring titanium ores that contain impurities. In this respect, Buff Titanium or Unbleached Titanium is a color that that may vary from one manufacturer to another.
Alternate Names
Off-White, Unbleached Titanium.
