ONE THAT COMES IN PACKAGING THAT IS INNOVATIVE, ELEGANT, HANDY AND FEELS RIGHT

The combination of Diarylide Yellow is a semi-opaque, moderately staining, intense, deep reddish yellow pigment with good tinting strength and has excellent lightfastness and permanence. However, it can fade in tints, so some artists do not consider it suitable for their colour.

However, when combined with Hansa yellow, it produces a transparent yellow with excellent brightness and tinting strength. When mixed with Titanium White, the most brilliant of the opaque white pigments, it results in a beautiful Cadmium Yellow Medium Hue without the toxin.

PIGMENT NAME: PY83-DIARYLIDE YELLOW 83

Pigment Type: Organic, disazo

Properties

Diarylide Yellow is a semi-opaque, moderately staining, intense, deep reddish yellow pigment with good tinting strength.

Permanence

Diarylide Yellow 83 has excellent lightfastness and permanence. However, it can fade in tints, so some artists do not consider it suitable for their colour. Many other diarylide yellow pigments have fair to poor lightfastness, and some are entirely fugitive. Diarylide Yellow 83 is reputed to be one of the most permanent of the entire group.

Toxicity

Diarylide Yellow has no significant acute hazards, but chronic hazards have not been well studied.

History

Diarylide Yellow belongs to a family of azo pigments known as Diarylide. These yellow-hued pigments were developed around 1940 and are very important in printing inks.

PIGMENT NAME: PW6-TITANIUM WHITE

Pigment Type: Inorganic

Chemical Name: Titanium dioxide

Properties

Titanium White is the most brilliant of the white pigments. It is considered an all-purpose oil colour 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 watercolour form. This pigment exhibits good chemical stability, and its tinting strength surpasses that of 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 biologically absorbed, even after prolonged exposure. The primary safety concern is with 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 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 the ancestor of the Titans, and the Greek word tito, meaning day or sun.

PIGMENT NAME: PY3-HANSA YELLOW 10G

Pigment Type: Organic, monoazo

Properties

This Hansa yellow is transparent. It has excellent brightness and tinting strength, and its drying time ranges from average to slow. Hansa Yellow makes more intense tints and cleaner secondaries than Cadmium Yellows, especially when mixed with other organic or modern colours like Phthalo Blue and Green. Because they are more transparent, they have great value as glazing colours.

Permanence

This Hansa Yellow has fair to good permanence, particularly in the lighter shades.

Toxicity

Hansa Yellow poses no significant acute hazards; however, its chronic hazards have not been well studied.

History

Hansa Yellows were first made in Germany just before WW1 from a series of synthetic dyestuffs called Pigment Yellow. They were intended to be a synthetic replacement for Cadmium Yellow.
