Description
A very special version of the classic green leaning blue, Cerulean Blue.
The pigment is specially made in the North West of England in small batches of no more than 5kg, very pure and clean, more details below;
"Coeruleum blue, cobalt-cerulean blue. CoO.n(SnO2). An artificial mineral pigment, made by roasting cobalt sulphate, tin salts and silica (cobalt stannate). Originally introduced in 1821."
The pigment is bound in pale oil to maximize the colour - the oil is a cleaned, cold pressed linseed oil, purified with fuller's earth to lighten the colour and remove any footings.
In masstone the paint is lighter than a lot of cerulean blues (i.e. not as green leaning and lighter in tone).
In tints it is relatively strong, and similar to other ceruleans, the tints have a wide range of slightly coolish blues, with less green edge than most.
It would function very well in a limited palette as a cool blue in opposition to a warmer ultramarine, or for those who find other ceruleans too green.
A real rarity.
