 His early research metallurgical dates from 1838, from a series of very remarkable memoirs succeeded until 1844, while others appeared only in 1851.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.He was a pioneer in the study of the chemical weathering of silicate minerals and basaltic rocks by carbonic acid.
