 When it has not been possible to characterise pigments fully, their elemental make up has been recorded as, for example, 'calcium-based' or 'copper-based'.
 
-**Egyptian blue** <a name="Egyptianblue"></a> and **Egyptian green** Manufactured pigments, prepared by firing copper minerals or metal with a calcium compound (like powdered limestone), silica and soda at high temperature. The principal colour component in Egyptian blue is calcium copper tetrasilicate (CaCuSi<sub>4</sub>O<sub>10</sub>), and in Egyptian green is cupro-wollastonite (CaSiO<sub>3</sub> with copper in the structure).
