Ultramarine
Ultramarine (translucent blue, azure blue), blue pigment, which was originally obtained by a mechanical process from the translucent stone (lapis lazuli) and was of very high value. It is now artificially produced, in equal beauty and very cheaply, from iron-free clay, sulfur and soda (soda ultramarine) or from clay, Glauber‘s salt and coal (sulphate ultramarine). A distinction is made between low-silica ultramarine with a light, pure blue hue, easily decomposed by alum, and high-silica ultramarine with a peculiar reddish hue and better resistance to alum.
