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.

• Pigment Name
  PG7-Phthalo Green
• Pigment type
  organic
• Chemical Name
  polychlorinated copper(II) phthalocyanine
• Chemical Formula
  C32H3Cl13CuN8 to C32HCl15CuN8 or C32H16CuN8Cl15 (PG7) or C32Br6Cl10CuN8 (PG36)
• Properties

  Phthalo Green is a transparent, cool, bright, high intensity color used in oil and acrylics. It comes from a Phthalocyanine Blue pigment where most of the hydrogen atoms have been replaced with chlorine, forming highly stable molecules. It has similar pigment properties and permanence to Phthalo Blue. It is slow drying and an excellent base color for mixing a range of bright greens. Phthalo Green is considered a very good alternative to Viridian because it is intense and mixes well and can be used to emphasize mineral colors in various tints. However, its tinting strength is very high, so it can overpower other colors. This pigment most closely resembles the discontinued and toxic Verdigris.

• Permanence

  Phthalo Greens are completely lightfast and resistant to alkali, acids, solvents, heat, and ultraviolet radiation. They are currently used in inks, coatings, and many plastics due to their stability and are considered a standard pigment in printing ink and the packaging industry.

• Toxicity

  Phthalo Green has no significant hazards, but it contained PCBs (polychlorinated biphenyls) until 1982.

• History

  This bright blue-green was developed in 1935 and has been in use since 1938.

• Pigment Name
  PB7-Phthalocyanine Blue
• Pigment type
  organic synthetic
• Chemical Name
  -
• Chemical Formula
  C32H16CuN8
• Properties

  Intense, clean blue with a slightly greenish undertone Extremely high tinting strength Semi-transparent (varies by formulation) Excellent chemical and solvent resistance Widely used in acrylics, oils, inks, plastics and coatings.

• Permanence

  Excellent lightfastness (ASTM I) Very high heat and weather resistance Outstanding long-term stability.

• Toxicity

  Generally considered low toxicity Avoid inhalation of dry pigment powder.

• History

  Discovered accidentally in 1927. Commercial production began in the 1930s. Replaced many traditional blues due to superior strength and durability.

• Pigment Name
  PY42-Mars Orange
• Pigment type
  inorganic, earth
• Chemical Name
  iron oxide
• Chemical Formula
  Fe2O2 or Fe2O3H2O
• Properties

  Mars Orange is a bright, extremely light red and appears almost pinkish in contrast with darker colors. It has incredible tinting strength and opacity. The synthetic form of Mars Orange is made from iron oxides and is cleaner, brighter, and denser than its ochre-based counterparts.

• 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
  PY43-Yellow Ochre
• Pigment type
  earth
• Chemical Name
  iron(III)-oxide, hydrated
• Chemical Formula
  Fe2O3
• 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.
