Rublev Colours Pigment Silver Pearlescent - 4 oz

Rublev Colours Silver Pearlescent pigment consists of mica that has been coated with titanium dioxide. The thickness and the coarseness of the particle determines the sparkle of the pigment, resulting in a metallic silver appearance.

Mica pearlescent pigments are synthetic pigments manufactured from mica, titanium dioxide, and metal oxides.

Pearlescent Pigments are Affected by Background

Due to their inherent transparency, the colour of pearlescent pigments can be affected by the colour of the material over which they are applied. When it is on a white background, the transmission colour can be seen at all angles, and the interference colour is not obvious. When it is on a black or dark substrate, the transmission colour is adsorbed by the substrate, and the interference colour is strong and bright at the specular angle. At the specular angle, the interference colour is observed. At diffuse angles, the complementary colour of that interference colour is seen because the light is transmitted through the film.

Permanence and Compatibility

Mica pearlescent pigments are synthetic pigments of varying colours that have not been rated for lightfastness ac cording to artist materials standards of the American Society of Testing and Materials (ASTM International), but are considered to be extremely lightfast. Mica pearlescent pigments are compatible with all pigments, and resist acids and alkalis and withstand high temperatures.

Oil Absorption and Grinding

Pearlescent pigments absorb a high amount of oil (65 to 100 grams per 100 grams of pigment), which may slow the drying of oil paint and hence makes a moderate to slow drying oil colour. It disperses well in both oil and water-based paints and is easier to mull due its large particle size.

Toxicity

Pearlescent pigments are not considered toxic, but care should be used in handling the pigment to avoid inhaling powder.
