PY35:1-Cadmium-Barium Yellow
inorganic
cadmium zinc lithopone
CdSZn + BaSO4
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. 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.
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.
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 pro
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.
PG18-Viridian
inorganic
chromium(III)-oxide dehydrate
Cr2O3 • 2 H2O or Cr2(OH3)
Viridian is the standard green and is stable, powerful, and cold with an emerald green undertone. It has a transparent hue, good tinting strength, a dark masstone that can be almost black at full strength, and a slow drying time in oil form. Viridian is commonly replaced by the darker, more saturated, and staining Phthalo Greens, but its properties make it a necessary part of the palette of an experienced landscape painter.
Viridian has excellent permanence, except in high-temperature work, and is highly valued as a glazing color.
Viridian is slightly toxic.
Viridian’s name comes from the Latin viridis, meaning green. The process for manufacturing Viridian, or Transparent Oxide of Chromium, was patented by Guignet in Paris in 1859. However, it had actually been discovered by Pannetier and Binet in 1838. Viridian replaced Verdigris, which was reactive and unstable, and Emerald Green, which was a poisonous copper aceto-arsenite used as a rat poison in the sewers of Paris.
