R&F Encaustic Paint Block - Cerulean Blue, 40 ml
It is a complicated colour. It is quite greenish when laid next to cobalt blue, yet under fluorescent light, it can take on a violet cast. Its large particle size makes it a little gritty and adds to its luminosity.

Chemical Composition: Cobalt (II) stannate
Properties
Cerulean Blue is the standard cool blue, considered the traditional counterpart to Ultramarine, and is often used for painting atmospheric shades. It quickly dries 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 could be higher, 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. Andreas Hopfner discovered this pigment in 1805, but it was not widely available until Messrs. G. Rowney Co. in England introduced it in 1860 under the name coeruleum for use in aquarelle and oil painting. It was produced by the action of heat on cobalt oxide and other metallic bases.
