Green earth, also known as terre verte and Verona green, is an inorganic pigment derived from the minerals celadonite and glauconite.[2][3][4] Its chemical formula is K[(Al,Fe3+),(Fe2+,Mg)](AlSi3,Si4)O10(OH)2.[5]
First used by the ancient Romans, green earth has been identified on wall paintings at
Green earths have been rather confusingly referred to as "verda terra" or "terra verde di Verona", which scholars have assumed incorrectly referred to Veronese green, which is actually an emerald green pigment much used in the 18th century., and carbon which have been added to change the colour tones.
High quality deposits can be found in England, France, Cyprus, Germany and at Monte Baldo near Verona in Italy.[7] The color ranges from neutral yellow green to pale greenish gray to dark matte olive green.[5][4]
