R&F Encaustic Paint Block - Green Gold Pale, 40 ml
Green Gold at full strength is a unique brownish green, but its very pale tint can be persuaded by other colours to lose even a hint of that green. Surround it with cadmium lemon, ultramarine blue pale, and warm pink to see how easily influenced it is. It is cooler than Brilliant Yellow Extra Pale and Sienna Yellow Extra Pale. Blend Green Gold with Titanium Zinc.

Pigment Name: PY129-Green Gold
Classification: Synthetic Organic, Polymethine
Chemical Composition: Copper azomethine green
Properties
A transparent greenish yellow pigment with low tinting strength.
Permanence
Pigment PY129 has been reported to have very good lightfastness.
Toxicity
Pigment PY129 is not considered to be hazardous.
History
Pigment Yellow PY129 has been used in automotive coatings.
Pigment Name: PW7-Zinc Sulphide White
Classification: Synthetic Inorganic
Chemical Composition: Zinc sulfide
Properties
Zinc Sulphide White is a semi-transparent yellowish-white pigment. Zinc sulphide and zinc oxide (PW4) are often combined to create a more natural white colour. Transparency increases as particle size decreases. When slight impurities are added, zinc sulphide has phosphorescent and electroluminescent properties. It is often used to manufacture fluorescent or glow-in-the-dark paints.
Permanence
Zinc Sulphide White has excellent permanence and lightfastness.
Toxicity
Zinc Sulphide is non-toxic, but ore deposits often contain lead. Traces of lead and other impurities may be present in pigment powders. Ingestion is not recommended.
History
Zinc sulphide, when combined with slight impurities, has phosphorescent properties. It is often used for invisible ink that glows with ultraviolet light and is also used in the manufacture of fluorescent paints.
Pigment Name: PW6-Titanium White
Classification: Synthetic Inorganic
Chemical Composition: Titanium dioxide
Properties
Titanium White is the most brilliant of the white pigments. It is considered an all-purpose oil colour that is useful in all techniques and the best all around white. Its masstone is neither warm nor cool, placing it 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 watercolour 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 the inhalation of fine pigment dust particles.
History
Titanium is the ninth most abundant element in the Earth's crust. However, mineral deposits that are economical to mine are rare. 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.
