History : Overseas blue was formerly obtained by grinding lapis lazuli, a fine stone resulting from volcanic fusion from Afghanistan. It is found in China, Tibet but also in Egypt during Antiquity. In the Middle Ages, it was used for illuminations. In the Renaissance, this pigment was so expensive that the artists ask directly to their patrons to pay it ! It was replaced by a synthetic pigment in the nineteenth century. At that time, 6000 francs of reward were promised to the person who would discover the way to manufacture ultramarine blue synthetically. It is the industrialist Jean-Baptiste Guimet, from Lyon, who receives the award in 1828. The reputation of the Guimet blue becomes worldwide by its use in paints and for the bluing of paper and linen.
