I also love Blue-Cobalt and found some information..."<br /> In 1824, the Societé d'Encouragement offered a prize of six thousand francs to anyone who could produce a synthetic variety not to exceed three hundred francs per kilo. The prize was not awarded for four years because all that was submitted to them were imitations based on cobalt or Prussian blue without regard for the analysis of the gem which was published in 1806 by Désormes and Clément. On February 4, 1828, the prize was awarded to Jean Baptiste Guimet who submitted a process he had secretly developed in 1826. Guimet's ultramarine was sold for four hundred francs per pound. In Paris a short while later, lapis lazuli cost between three to five thousand francs per pound at that time. http://www.webexhibits.org/pigments/indiv/history/ultramarine.htmlVinhhttps://www.blogger.com/profile/06206910097192566482noreply@blogger.com
