National Gallery article: “Fading and Colour Change of Prussian Blue: Methods of Manufacture and the Influence of Extenders” by Jo Kirby and David Saunders, 2004. It is extraordinary that what was once the most expensive colour has become one of the most widely available. In 1826 Ultramarine Blue, a synthetic pigment that is chemically identical to lapis lazuli, was created. If you need blue in your paintings, You’ll probably need ultramarine too.” The 18th Century saw the development of Prussian and Cerulean Blue, followed by Cobalt Blue in the early 19th Century. Sinopia sells completely lightfast blue and violet. The prussian blue and cobalt oxide films have been synthesized via a simple galvanostatic method to achieve better film quality to be used in a device. Prussian blue inclines toward green, whereas ultramarine inclines toward purple. Cobalt Blue, Prussian Blue, Cobalt Violet, and Phathlo Blue are very common colors to artists today. An all-inorganic, fast, and power-efficient solid-state electrochromic device has been realized by choosing Co3O4 and PB films as complementing electrodes. In response to someone asking if Prussian Blue can be a substitute for Ultramarine Blue: “Prussian blue is quite different from ultramarine, so would not make a good substitute for it. Its qualities include: transparent, very good lightfastness, high oil content, non-toxic and very fast drying. It goes by other names: Berlin Blue, Paris Blue, Antwerp Blue, Milori Blue, Brunswick Blue, Turnbull’s Blue, Chinese Blue, among others. Prussian Blue, considered the earliest of our synthetic, inorganic modern pigments, was first synthesized by the paint maker Diesbach in Berlin around 1706. PB35 is opaque whereas PB 36 is more transparent, has higher tinting strength, and is darker in value than PB 35. It was made by German chemist Diesbach around 1704 making it the first synthetic blue pigment. R&F Prussian Blue is a single pigment color. Some paint manufacturers label it cerulean blue but the proper name should be cobalt chromite blue. I will repeat my oil paint forum post here: This is an easy decision. Note: there is also PB36 made from oxides of cobalt and chromium. Fake cerulean made with phthalocyanine blue does horrible things in flesh tone mixtures. If it isn’t real cerulean blue, it isn’t worth trying to save or use. It’s a mixture of phthalocyanine blue and zinc white or titanium white, or both. It’s useful for painting flesh tones of light-complected people.īeware of a paint labeled: “cerulean blue hue”. Mixing it thoroughly with a small amount of linseed or walnut oil will bring it to a smooth, controllable consistency. It’s an expensive pigment with good lightfastness. Real Cerulean Blue (PB 35, cobalt stannate) is a compound of cobalt and tin.
