Color Swatch created using heavy application/medium application/50% tint and was applied on acrylic primed canvas (7 oz) material.
This color contains the following pigments:
PW20—Mica
Pigment Type
inorganic
Chemical Name
aluminum silicate
Chemical Formula
H2KAl3(SiO4)3
Properties
An off-white pigment with complex reflective effects, mica is often used with transparent pigments to create mixed pigments with interference and pearlescent effects.
Permanence
Mica is permanent and lightfast.
Toxicity
Although it is completely non-toxic and not bioreactive, fine particles may be irritating. This is of concern primarily for those exposed occupationally to dry mica powder. Breathing mica particles may cause lung fibrosis and pneumoconiosis.
History
Mica has been used as a pigment since prehistoric times.
