Yellow Ochre provides artists with earthtones from cream to brown. It has good hiding power, produces a quick drying paint, and can be safely mixed with other pigments. Its transparency varies widely from opaque shades to more transparent ones, which are valued for their use as glazes. If gypsum is present, Yellow Ochre is not suitable for frescoing. (See Brown Ochre, PY43.) PY42 is made from synthetic iron oxides. PY43 is made from natural iron oxide.
Yellow Ochre has excellent permanence because ochres are some of the most permanent pigments available.
Yellow Ochre is non-toxic unless it contains manganese.
Ochre comes from the Greek word ochros, meaning pale yellow. It was one of the first pigments to be used by human beings, and evidence of its use has been found at 300,000 year old sites in France and the former Czechoslovakia.

Lithopone is a low tinting strength, semi-transparent white pigment that is often used as a filler or extender in other colors, or as the base for laked pigments.
Lithopone is absolutely permanent and lightfast.
Lithopone is not toxic.
Lithopone was discovered by G.F. de Doubet in 1850. It was developed commercially in the 1870s as a substitute or supplement for lead carbonate, to overcome the many shortcomings of white lead pigment, including toxicity, poor weathering, and darkening in the presence of sulfur compounds. It is used most often in interior paints and enamels. Its use as a white pigment has been superceeded in many applications by titanium dioxide.
