Green earths

A variety of mineral ores, mostly copper minerals such as malachite and chrysocolla, were probably the most used green pigments in the past. Various green minerals derived from metals other than copper, such as green earth (see below) were used in confined regions. 

Green earth, best known by the Italian name terra verte, is probably the main green pigment not derived from copper. Terra verte is a mixture of two minerals, caledonite and glauconite, both complex silicates of aluminum, calcium, iron, magnesium, and potassium silicate (Grissom 1986).

Green pigments were chrysocolla, malachite, or other basic carbonates of copper and appianum, a green earth or chalk said to be a cheap and inferior color. 

Figure 16 shows the spectra obtained for two other pigments— green earth and Prussian blue. In the former case there are actually two spectra, one of which consists of a widely split doublet typical of iron (II) compounds. Heating this pigment changes it to a brownish-red and removes the ferrous doublet.

The moist green earth was a blue-white pearl.
