Abstract Acrylic Pouch - Satin 921 Light Violet 120ml

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

Phthalo Blues are pure and clean primary blues with superior covering power. They have a very high tinting strength and tend to overwhelm other pigments. When mixed with some white can be semi-transparent. Dioxazine Violet is transparent and has very high tinting strength. It is a staining pigment, very dark valued when used at full strength, but mixes with opaque Titanium White to form bright, opaque tints of purple.

COMPOSITION AND PERMANENCE

Pigment Combination: PB15-Phthalo Blue; PV23-Dioxazine Violet; PW6-Titanium White

1 PIGMENT NAME: PB15-PHTHALO BLUE

Pigment Type: Organic

Chemical Name: Copper phthalocyanine

Properties

Phthalo Blues are pure and clean primary blues with superior covering power. They have a very high tinting strength and tend to overwhelm other pigments, but they make predictable mixed colours if colour strength can be controlled. In oil form, blues are intense and slow drying. When mixed with other colours or added chlorine, Phthalo Blue quickly tends towards green. When using alone, mix with some white, as Phthalo Blue can be semi-transparent and almost black on its own. It is among the most compatible modern colours with mineral colours and is considered more reliable than Prussian Blue while sharing the same physical and colour properties. Phthalo Blue is a good colour for glazing.

Permanence

Phthalo Blues are completely lightfast and stable and are permanent for all paint uses. Due to their stability, they are currently used in inks, coatings, and many plastics and are considered a standard pigment in printing ink and the packaging industry.

Toxicity

Phthalo Blues have no significant hazards, although those made before 1982 contained some PCBs (polychlorinated biphenyls).

History

Developed by chemists using the trade name Monastral Blue, the organic blue dyestuff is now known as Phthalo Blue, was presented as a pigment in November 1935 in London. Its discovery was accidental. The dark colour was observed in a kettle where a dye was being made from a British dyestuff plant. The demand for such a pigment came from commercial printers who wanted cyan to replace Prussian Blue.

2 Pigment Name: PV23-Dioxazine Violet

Pigment Type: Organic

Chemical Name: Carbazole dioxazine

Properties

Dioxazine Violet is transparent and has very high tinting strength. It is a staining pigment, very dark, valued when used at full strength. Concentrated, it paints out nearly black, but it mixes with Titanium White to form bright, opaque tints of purple. PV23 produces slightly redder shades than PV37. Because the hue can vary with the conditions of preparation and grinding, it may be offered in a red shade, blue shade, and so forth.

Permanence

Dioxazine Violet has a good lightfastness. There may be some concern about fading or shifting colour in tints and washes. Some artists have reported that PV37, a molecular variant, is more lightfast than PV23.

Toxicity  n/a

History

Two molecular variants of Dioxazine Violet, PV23 and PV37, are available. They have similar properties but mix slightly differently.

3 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.
