Cobalt has been used to make blue glass and ceramics for thousands of years by cultures across the world, including in China, Mesopotamia, and Egypt. The pigment we know today as Cobalt Blue (PB28) was synthesised in 1802 by Louis Jacques Thénard, who described it as ‘a blue colour as beautiful as Ultramarine'.

Cobalt Blue is a vibrant, rich pigment with a storied history. Jean-Antoine Chaptal (a minister appointed to first consul Napoleon Bonaparte) commissioned a chemist by the name of Louis Thénard to develop affordable blue colouring materials. Its sister pigment, Cobalt Blue Deep, was developed with a darker, red shade and powerful granulating properties. It has since become a popular choice among artists, known for its versatility, durability and rich colour. | Winsor & Newton
