ONE THAT COMES IN A PACKAGING THAT IS INNOVATIVE, ELEGANT, HANDY AND FEELS RIGHT.
Naples Yellow is great for nature and landscape paintings. Diarylide Yellow is a semi-opaque, moderately staining, intense deep reddish yellow pigment with good tinting strength. This Hansa yellow is a transparent, bright, clean yellow that makes more intense tints. Both yellows mixed with opaque Titanium White, the most brilliant white pigments, create a pure Naples yellow.
COMPOSITION AND PERMANENCE
Pigment Combination: PY83-Diarylide Yellow 83; PW6-Titanium White; PY3-Hansa Yellow 10G
1 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 comes from a family of azo pigments called Diarylide. These yellow-hued pigments were developed around 1940 and are very important in printing inks.
2 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 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.
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.
3 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 has no significant acute hazards, though 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.
