Wallace Seymour Cerulean Blue Bespoke Oil Paint

Cerulean English Blue PB 26

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.

Weak tinting strength, pure, delicate blue. Semi-transparent, slightly less so than cobalt blue. Stable in oil but because cerulean blue shows a tendency towards green when milled with linseed oil, this special shade is produced with Poppy oil. The fastdrying properties of cerulean blue assist rapid film formation of poppy oil.

Dries 2-3 days.
