Cobalt is a cool, slightly desaturated blue, historically made using cobalt salts. The blue seen on many glassware pieces is cobalt blue and is used widely by artists. It was discovered by Louis-Jacques Thenard in 1802. The world leading manufacturer of cobalt blue in the 19th century was Blaafarveværket in Norway, led by Benjamin Wegner. It is extraordinarily stable. Chemically it is a cobalt(II) oxide-aluminium oxide, or cobalt aluminate. Commercial production began in France in 1807. John Varley suggested it as a good substitution for ultramarine blue for painting skies.
