Rublev Colours Pigment Verona Green Earth - 100 g

Green earth, also widely known as terre verte, is primarily composed of the minerals celadonite and glauconite. The presence of celadonite or glauconite, minerals of complex silicate composition, produces colors that vary from cold bluish greens to warmer yellow and olive hues. It may have been formed originally from biotite (a dark-colored mica), but other minerals, and even organic matter, may change it into glauconite. The mineral has a micaceous structure, a silicate crystallized in monoclinic forms that readily separates into very thin leaves. It is characteristically formed on submarine elevations of ancient seabeds ranging in depth from 30 to 1,000 meters (100 to 3,300 feet) below sea level and in the sedimentary rocks of different geological systems. Usually, it forms small (from 0.8 to 1.5 mm in diameter) green round or angular grains.
