In its laboratory of Prussia he discovers in 1745 that the fodder Betterave - ancestor of current sugar beet - contains “not only one element resembling the Sucre”, but “of genuine sugar, perfectly identical to that which one knows of the cane with sugar”.
He discovered the acids formic and phosphoric. He insulated in 1746 the Zinc by heating Calamine and coal and in 1754 the Alumine starting from the Alun.
