Ultramarine blue dark artist color with high pigment content, pure linseed oil and without solvents. The consistency is like butter at room temperature, and for many artists the paint can be used directly from the tube without the addition of medium.
Ultramarine blue PB29 (Na2SO4), is a deep blue and warm blue. Ultramarine comes from the Latin and Old Venetian ultramarinus, which means overseas. It came shipped by boat to Venice in the 14th century, but has been part of Chinese art 500 years earlier. It originally came from mines in Afghanistan in the form of the rock crystal Lapis Luzili. It was ground to a fine powder and mixed with binder such as eggs and later oil so that it could be used in art production. Through the rennaisance, it was the absolute most expensive pigment to make paint from. So expensive that it was three times more expensive than gold at one point. Therefore, it was often used only to paint drapes on the clothes of the Virgin Mary in thin glaze over the cheaper blue color Azurite.
By 1826, the chemists had become so skilled that the specialty of ultramarine could be manufactured synthetically and a lot cheaper. Even that was some time along the way. In 1814, Jean-Joseph-François Tassaert saw by chance the formation of blue soot identical to the ultramarine in a lime kiln at St Gobain. Subsequently, attempts were made to replicate the phenomenon in a series of experiments. It was the chemists Jean Baptiste Guimet and Christian Gmelin who invented the synthetic pigment that we all use today when we paint with ultramarine.
This oil paint can be mixed with oil paints from other manufacturers. The same goes for medium. Since this is such a chemically pure and simple product without mysterious fillers, it must also be mixed with your own favorite medium, whether it is dammar and linseed oil, stand oil, black oil with litharge, Liquin ™, Oleogel ™ Maroger, lavender spike oil, etc. For good control over consistency and detail work, we recommend our own paint. If you use solvents to clean brushes outdoors or in a ventilated room, Gamsol ™, turpentine, Terpenoid ™ Alcohol and ethanol, etc can be used. If, on the other hand, you do not like solvents, you can use special cleansing soap or liquid brown soap for the same purpose.
Ultramarine blue dark is not toxic / toxic, but must not be eaten or otherwise ingested. The product has not been allergy-tested, but if you only use it for its intended purpose – to paint with a brush and palette knife – there is no immediate health risks.
