History


Pigment Name

PW20-Mica

Pigment Type

inorganic

Chemical Name

aluminum silicate

Chemical Formula

H2KAl3(SiO4)3

Properties

An off-white pigment with complex reflective effects, mica is often used with transparent pigments to create mixed pigments with interference and pearlescent effects.

Permanence

Mica is permanent and lightfast.

Toxicity

Although it is completely non-toxic and not bioreactive, fine particles may be irritating. This is of concern primarily for those exposed occupationally to dry mica powder. Breathing mica particles may cause lung fibrosis and pneumoconiosis.

History

Mica has been used as a pigment since prehistoric times.


Pigment Name

PW6-Titanium White

Pigment Type

inorganic

Chemical Name

titanium dioxide

Chemical Formula

TiO2

Properties

Titanium White is the most brilliant of the white pigments. It is considered an all purpose oil color useful in all techniques and the best all around white. Its masstone is neither warm nor cool, placing it somewhere between Lead White and Zinc White. It is less prone to cracking and yellowing than Lead White, but it still yellows easily. Titanium White dries slowly in oil form, more slowly than Lead White but more quickly than Zinc White. It is opaque in oil and acrylic forms and semi-opaque in watercolor form. This pigment has good chemical stability, and its tinting strength is superior to both Lead White and Zinc White.

Permanence

Titanium White has excellent permanence and lightfastness.

Toxicity

Titanium dioxide is highly stable and is regarded as completely non-toxic. Animal studies give no indiciation that it is absorbed biologically, even after long periods of exposure. The primary safety concern is with inhalation of fine pigment dust particl

History

Titanium is the ninth most abundant element in the Earth's crust, however mineral deposits that are economical to mine are less common. Titanium dioxide was first discovered in 1821, although it could not be mass produced until 1919. Widespread use of the pigment began in the 1940s. Since that time, it has become the most commonly used white pigment. The name comes from the Latin word Titan, the name for the elder brother of Kronos and ancestor of the Titans, and from the Greek word tito, meaning day or sun.


Pigment Name

PBr7-Burnt Sienna

Pigment Type

earth

Chemical Name

iron oxides

Chemical Formula

Fe2O3

Properties

Burnt Sienna is a warm, mid-brown color formed by burning the yellow-brown limonite clay called Raw Sienna. It ranges from semi-opaque to semi-transparent due to the combination of its opaque, red-brown mass tone and its transparent, orangey undertone. It is an excellent mixing complement for blues and greens and creates salmon or peach colored tints when mixed with white. It can be useful for subduing bright colors and does not get chalky in dark mixtures.

Permanence

Burnt Sienna has good permanence and is considered one of the most versatile of the permanent pigments.

Toxicity

Burnt Sienna has no significant hazards.

History

Burnt Sienna has been used as a pigment since prehistoric times, but its current name came about during the Renaissance. It comes from the city of Siena, in Italy, and is short for terra di Siena, meaning earth of Siena. Sienna was famous for the mining and production of earth pigments from the Renaissance until World War II. Due to the depletion of clay deposits in Tuscany, Italian siennas now come from other areas, including Sicily and Sardinia.


Pigment Name

PY42-Yellow Ochre

Pigment Type

Chemical Name

iron(III)-oxide, hydrated

Chemical Formula

Fe2O3 • H2O

Properties

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.

Permanence

Yellow Ochre has excellent permanence because ochres are some of the most permanent pigments available.

Toxicity

Yellow Ochre is non-toxic unless it contains manganese.

History

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.


Pigment Name

PBr6-Mars Brown

Pigment Type

Chemical Name

iron oxide

Chemical Formula

Fe2O3

Properties

Mars Brown has similar general properties to the pure red oxides, and it is often a mix of synthetic forms of oxides such as PY42, PR101, and PBk11. Its tinting strength is low, and it dries quickly. Hues vary based on manufacturer.

Permanence

Mars Brown has excellent permanence and lightfastness, with outstanding resistance to chemicals, heat, and weather.

Toxicity

Mars Brown is not considered toxic, although care should be taken not to breathe its dust.

History

Unknown.


Pigment Name

PR101-Red Iron Oxide

Pigment Type

earth, synthetic

Chemical Name

iron oxides (synthetic), iron oxide, silica, alumina, lime, and magnesia or hydrated iron oxide

Chemical Formula

Fe2O2 or Fe2O3 • H2O

Properties

Red iron oxide varies in hue and transparency, depending on hydration and slight impurities. Indian Red is a slightly duller, deep brick hue with a bluish undertone. It is very dense and opaque, with excellent tinting strength and covering power. It is dependable when mixing with all other permanent pigments and yields good flesh tints when mixed with Zinc White. It is the synthetic version of PR102, which is a pigment made from earth reds, or natural red iron oxides, and the names applied to PR101 and PR102 often overlap. The synthetic red iron oxides have mostly replaced natural red iron oxides and are brighter, stronger, finer, and more permanent. Indian Red is the highest grade bluish shade. Light Red, English Red, and Venetian Red are yellowish shades. Mars Violet is a dull and subdued bluish or purplish oxide.

Permanence

Red iron oxide is very lightfast with excellent permanence.

Toxicity

Red iron oxide has no significant hazards.

History

Natural red iron oxide comes from the mineral ore hematite, called bloodstone by the ancient Greeks from the word hema, meaning blood. It is one of the oldest pigments, has been used by every major civilization, and was an important mineral for medieval alchemists. It was not widely used in artists' materials until the 17th century and was not produced in large quantities until the 18th century.


Pigment Name

PR102-Natural Light Red Iron Oxide

Pigment Type

inorganic, natural

Chemical Name

iron oxide

Chemical Formula

Fe2O2

Properties

Natural Light Red Iron Oxide is a brick red pigment with a bright, scarlet top tone. Mineral sources vary considerably in both hue and transparency. It is generally opaque and has great tinting strength and hiding power, but more transparent versions are available. It creates salmon pinks when mixed with white. Natural Light Red Iron Oxide is often replaced by Mars colors or bright red oxides, which are cleaner and more powerful.

Permanence

Natural Light Red Iron Oxide has excellent permanence and lightfastness.

Toxicity

Natural Light Red Iron Oxide has no significant hazards.

Pigment Name

PM1-Aluminum

Pigment Type

inorganic

Chemical Name

aluminum

Chemical Formula

Properties

Powdered aluminum is used to create silvery metallic and interference effects.

Permanence

Aluminum powder is lightfast, but it must be protected from oxidation. Under normal conditions, aluminum metal is protected by a thin layer of oxides that forms on the metallic surface.

Toxicity

Aluminum is an abundant element, but it occurs naturally in non-toxic forms as a mineral oxide, not as a metal. Aluminum metallic powder is considered safe when it is suspended in an acrylic binder, for use in specialty artist and craft paints. Aluminum m

History

Although aluminum is an abundant element in the Earth's crust, it was a semi-precious metal until the late 19th century, when an electrolytic process was developed for extracting aluminum from the mineral oxide forms in which it naturally occurs.
