Description from the manufacturer
Sienna is named after the city of Siena, Italy. It is a yellow-brown earth pigment originally sourced from the Italian province of Tuscany, but can be found in other areas. This ‘burnt’ variation is produced by heating the raw pigment. This process, called calcination, partially converts the brown iron oxides into hematite, a red iron oxide. Burnt Sienna finds a classic mixing partner in Ultramarine Blue, with which it makes some enigmatic greys.
