Gamblin 1980 Oils - PBr7-Burnt Umber

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.

Burnt Umber: Vigorous drier due to high manganese content. Burnt Umber is helpful as an underpainting drawing colour. Because of the high oil content, use thinly in under layers.

PIGMENT COMPOSITION AND PERMANENCE

• Pigment Name: PBr7-Burnt Umber (Calcined natural iron oxide, manganese)
• Pigment Type: earth

PROPERTIES

Burnt umber is a more intense reddish-brown pigment produced by heating Raw umber's clay pigment. It has medium to excellent tinting strength and high opacity and is quick-drying in oil form. Burnt Umber is more transparent than Raw Umber.

It has excellent colour properties and can create a variety of subtle, clear tints when mixed with white.

It can tend towards chalkiness in dark oil mixes, but overall, it mixes well with other colours. To create a black colour in oil form, mix Burnt Umber with Phthalo Blue or Ultramarine. Mix it with Ultramarine or Payne's Gray to achieve a similar colour in watercolour form.

PERMANENCE

Burnt Umber has good permanence.

TOXICITY

Burnt Umber itself is considered non-toxic. If contaminated by manganese compounds, it may be highly toxic if inhaled and moderately toxic if ingested.

HISTORY

This pigment comes from the Latin word umbra, meaning shadow or shade. Its full name is terra di ombra, meaning earth of shadow/shade, due to its original extraction from Umbria, Italy. It has been used as a pigment since prehistoric times. Currently, the finest umber comes from Cyprus.
