[1] In 1836 he was sent to Vesoul as a mining engineer, and began studying the different ores at Franche-Comté, where his reputation grew, growing artificial crystals of a number of minerals including corundum, chrysoberyl and peridot.

He stayed there for four years, before committing himself in 1841 as assistant secretary of Committee of the Annales des Mines and a lecturer of chemistry at École Polytechnique.

He was also appointed professor of mineral assay at the Ecole des Mines and was made a Knight of the Legion of Honor by King Louis-Philippe in April 1847.

Whilst in England, his innovations drew esteem from the greatest scholars, including Michael Faraday, who invited him to attend a lecture he professed before the Royal Institution in London.

To determine the composition of the gases successively in blast furnaces, kilns in a puddle in the warming ovens, he was inventing special processes, to draw the gas mixture in warmer regions and most easily accessible, and applied the same methods to study the carbonization of wood in the wheels, to that of the carbonization of coal in coke ovens and review of combustion in the engine locomotives homes alongside Frédéric Sauvage.
