R&F Encaustic Block, Cerulean Blue 40ml

R&F Encaustic Paint Block - Cerulean Blue, 40 ml

A complicated colour. It is quite greenish laid next to cobalt blue and yet under fluorescent light, it can take on a violet cast. Its large particle size makes it a little gritty but also adds to its luminosity.

Properties

Cerulean Blue is the standard cool blue, considered the traditional counterpart to Ultramarine, and is often used for painting atmospheric shades. It is quick drying and retains its colour well, better than any other blue, in oil paint form. However, it tends to granulate or become chalky in watercolours. It has limited hiding power, is semi-opaque, and is easy to control. Its tinting capacity is low, so it can become lost when mixing.

Permanence

Cerulean Blue has excellent permanence. It is very stable and lightfast.

Toxicity

Cerulean Blue is moderately toxic if inhaled or ingested and slightly toxic if it comes into contact with skin.

History

The name Cerulean Blue comes from the Latin word caelum, meaning sky. This pigment was discovered in 1805 by Andreas Hopfner, but it was not widely available until introduced by Messrs. G. Rowney Co. in England under the name coeruleum in 1860 for use in aquarelle and oil painting. It was produced by the action of heat on cobalt oxide and other metallic bases.
