Ultramarine is the standard warm blue, a brilliant blue pigment that has the most purple and least green in its undertone. It has a moderate to high tinting strength and a beautiful transparency. Synthetic Ultramarine is not as vivid a blue as natural Ultramarine. Ultramarine dries slowly in oil and tends to produce clean, though granular, washes in watercolor. French Ultramarine mixes well with Alizarin colors in oil and watercolor form to create a range of purples and violets. It can dull when mixed with white in acrylic form, but mixes well with other colors. The shade varies based on manufacturer. Considered a great color for glazes, it is not suitable for frescoing.
Ultramarine has excellent permanence, although synthetic Ultramarine is not as permanent as natural Ultramarine. It may discolor if exposed to acid because of its sulfuric content.
Ultramarine has no significant hazards.
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 colors on their palettes.
PR233-Chrome Tin Pink Sphene
inorganic
CaO + SnO2 + SiO2 + Cr2O3
Chrome tin pink sphene comprises a mixture of silicates and metal oxide salts. The opacity of the formulation depends on the proportions of these salts. Tinting strength is low compared with most organic pigments.
The inorganic metal salts in this pigment are extremely stable.
Chrome tin pink sphene comprises a mixture of silicates and metal oxide salts. Although none are known to be carcinogenic or toxic, fine particles of such materials are respiratory and eye irritants. Contact with dust should be avoided.
This inorganic pigment has been used in enamels and ceramic glazes. Naturally occurring mineral deposits have been used in ceramic glazes for centuries.
