Ultramarine violets and reds were developed in Germany ca. 1875; they are produced by treating ultramarine blue with sal ammoniac or dry hydrochloric acid gas at high temperatures. Ultramarine violet is stable, but it has poor tinting strength and is rarely used in artists' paints. ]]></dc:description></metadata>
