Terra verte

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). [Pg.99]

Green earths or Terras vertes are green-coloured due to concentrations of the clay minerals celadonite or glauconite. [Pg.146]
