Πληροφορίες Χρωστικής

• 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 do not indicate that it is absorbed biologically, even after long periods of exposure. The primary safety concern is with inhalation of fine pigment dust particles. If inhaled in large amounts over several years, Titanium White may cause benign pneumoconiosis visible on x-rays. The National Institute of Occupational Safety and Health (NIOSH) considers fine titanium dioxide particles, if inhaled, to be a human carcinogen. The primary concern for artists is to avoid exposure to fine particulate dust from raw pigments.

• 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.

It is not as black as Ivory Black, but it dries more quickly and has three times the tinting strength. Mars Black is normally the only black available in acrylic form and that is safe to over paint. It can be used in all media without reservation and is widely used as an alternative to Lamp Black and Ivory Black.

  Mars Black is very lightfast with excellent permanence.

• Toxicity

  Mars Black has no significant hazards and is the only major black pigment considered non-toxic.

• History

• Permanence

  Mars Orange has excellent permanence and lightfastness.

• Toxicity

  Mars Orange has no significant hazards.

• History

  The word Mars refers to the Roman god of iron and war. Mars Orange has been manufactured as a pigment since the 17th century.

• 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 x 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.
