Description of the artist pigment ultramarine blue
History of Ultramarine Artist Pigments
Historically, ultramarine was mined in Asia as a natural mineral. Its earliest recorded use was in ancient caves in Afghanistan and China and other areas close to where it was mined. Up through the middle ages and the Renaissance, this pigment was very expensive and difficult to obtain. During the early 19th century however a substance like ultramarine was discovered in a kiln and the mass production of synthetic ultramarine began. And by adjusting the proportion of ingredients or the process, other ultramarine pigments where able to be made such as ultramarine violet and pink.
How Can Ultramarine Blue Pigment Be Used By Artist
Ultramarine can be used in most mediums as long as it is not allowed to get in contact with even diluted acids. It can be used to pigment, oil paints, water color, milk and casein paint, watercolors, acrylics, plaster, cement and even soap. It is lightfast and very brilliant and intense.
Ultramarine blue can also be blended with titanium white to imitate the more expensive and toxic cobalt blue pigment. This is important if you want to airbrush cobalt blue.
