Description from the manufacturer
While Umber pigments are traditionally from the Italian region of Umbria, this one is sourced from Cyprus. This ‘burnt’ variation is produced by heating the raw pigment– a process, called calcination, which partially dehydrates the brown iron oxides and transforms them into red iron oxides. Mixed with white it makes some gentle pinks.
