Gamblin 1980 Oils - PBr7-Burnt Sienna (Calcined natural iron oxide)

Gamblin’s approach is different. 1980 colours contain pure pigments, the finest refined linseed oil, and marble dust (calcium carbonate). Since oil painting began, these three ingredients have made more affordable colours.

Painters experience true colours without homogenized texture or muddy colour mixtures. Gamblin's approach to using traditional raw materials and processes ensures that artists experience the luscious working properties they expect from their oil colours.

PIGMENT COMPOSITION AND PERMANENCE

• Pigment Name: PBr7-Burnt Sienna (Calcined natural iron oxide)
• Pigment Type: earth

PROPERTIES

Burnt Sienna is a warm, mid-brown colour formed by burning the yellow-brown limonite clay called Raw Sienna. Due to the combination of its opaque, red-brown mass tone and its transparent, orangey undertone, it ranges from semi-opaque to semi-transparent.

It is an excellent mixing complement for blues and greens, creating salmon or peach-coloured tints when mixed with white. It can help subdue bright colours and avoid getting chalky in dark mixtures.

PERMANENCE

Burnt Sienna has good permanence and is considered one of the most versatile permanent pigments.

TOXICITY

Burnt Sienna has no significant hazards.

HISTORY

Burnt Sienna has been used as a pigment since prehistoric times, but its current name came about during the Renaissance. It comes from Siena in Italy and is short for terra di Siena, meaning the earth of Siena.

Sienna was famous for mining and producing earth pigments from the Renaissance until World War II. Due to the depletion of clay deposits in Tuscany, Italian siennas now come from other areas, including Sicily and Sardinia.
