Abstract Acrylic Pouch - Satin 303 Cobalt Blue Hue 120ml

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

Modern-day pigments transparent Phthalo Blue PB15:1 is a structural variant of Phthalo Blue PB15 that produces more reddish tones, combined with a transparent Ultramarine is the standard warm blue. This brilliant blue pigment has the most purple and least green in its undertone. The synthetic Ultramarine is not as vivid a blue as natural Ultramarine. But when combining the Phthalo Blue (red shade)and Ultramarine with the opaque Titanium White, the most brilliant white pigments are the perfect combination to make a beautiful brilliant “opaque” Cobalt Blue Hue.

COMPOSITION AND PERMANENCE

Pigment Information: PB15:1-Phthalo Blue; PW6-Titanium White; PB29-Ultramarine [Blue]

1 PIGMENT NAME: PB15:1-PHTHALO BLUE

Pigment Type: Organic

Chemical Name: Alpha copper phthalocyanine

Properties

Phthalo Blue PB15:1 is a structural variant of Phthalo Blue PB15 that produces more reddish tones.

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: 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: PB29-Ultramarine [Blue]

Pigment Type: Inorganic

Chemical Name: Complex silicate of sodium and aluminum with sulphur

Properties

Ultramarine is the standard warm blue, a brilliant blue pigment with the most purple and least green in its undertone. It has a moderate to high tinting strength and beautiful transparency. Synthetic Ultramarine is not as vivid a blue as natural Ultramarine. Ultramarine dries slowly in oil and produces clean, though granular, washes in watercolour. French Ultramarine mixes well with Alizarin colours in oil and watercolour form to create a range of purples and violets. It can dull when mixed with white in acrylic form but mixes well with other colours. The shade varies based on the manufacturer. Considered a great colour for glazes, it is not suitable for frescoing.

Permanence

Ultramarine has excellent permanence, although synthetic Ultramarine is not as permanent as natural Ultramarine. It may discolour if exposed to acid because of its sulfuric content.

Toxicity

Ultramarine has no significant hazards.

History

The name for this pigment comes from the Middle Latin ultra, meaning beyond, and mare, meaning sea because it was imported from Asia to Europe by sea. It is a prominent component of lapis lazuli and was used on Asian temples starting in the 6th century. It was one of the most expensive pigments in 16th century Europe, worth twice its weight in gold, and so was used sparingly and when commissions were larger. Ultramarine is currently imitated by a process invented in France in 1826 by Jean Baptiste Guimet, making blue affordable to artists and extending the range of colours on their palettes.
