PR233-Chrome Tin Pink Sphene
PBr7-Raw Umber
PY42-Yellow Iron Oxide
PR233-Chrome Tin Pink Sphene
inorganic
CaO + SnO2 + SiO2 + Cr2O3
Chrome tin pink sphene comprises a mixture of silicates and metal oxide salts. The opacity of the formulation depends on the proportions of these salts. Tinting strength is low compared with most organic pigments.
The inorganic metal salts in this pigment are extremely stable.
Chrome tin pink sphene comprises a mixture of silicates and metal oxide salts. Although none are known to be carcinogenic or toxic, fine particles of such materials are respiratory and eye irritants. Contact with dust should be avoided.
This inorganic pigment has been used in enamels and ceramic glazes. Naturally occurring mineral deposits have been used in ceramic glazes for centuries.
PBr7-Raw Umber
earth
hydrated iron oxide
α-FeO3+(OH) or Fe2O3 × MnO2
Raw Umber is a cool, transparent brown ranging from yellowish brown to greenish brown. It has surprisingly good tinting strength, a high level of opacity, mixes well with greens, and is quick drying in oil form. It has excellent color properties and can create a variety of subtle, clear tints when mixed with white. It grays when mixed with blue and white. Raw Umber can tend towards chalkiness in dark mixes in oil form.
Raw Umber has excellent permanence.
Raw Umber itself is considered non-toxic. If contaminated by manganese compounds, it may be highly toxic if inhaled and moderately toxic if ingested.
This pigment gets its name from the Latin word umbra, meaning shadow or shade. Its full name is listed as terra di ombra, meaning earth of shadow/shade, due to its original extraction from the area of Umbria, Italy. It has been used as a pigment since prehistoric times. Currently, the finest umber comes from Cyprus.
PY42-Yellow Iron Oxide
iron(III)-oxide, hydrated
Fe2O3 • H2O
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.
