Anotations

Scope note:

Refers to a fine grade of Prussian blue, having a finer luster and a bronze sheen, favored in printing inks. It is also used in paints, enamels, and lacquers. Considered one of the three best grades of Prussian blue. Chinese blue (BaCuSi4O10) is more stable in chemical structure and fades less easily than Chinese purple.
