Vogt recognized the early inclinations for mining and metallurgy and promoted his mining career. He got his first job at the age of 18 in the Riegelsdorf mine in Hesse . From 1798 he gained further knowledge in mines in the Thuringian Forest , in Franconia , on the Upper and Lower Rhine and in Hessen-Nassau .

After abandoning his chemistry studies with Professor Johannes Schaub (1754-1818) in Kassel, he took over the management of his brother-in-law Vogt's blue color factory in Sankt Andreasberg . From 1804 he became a mountain master in Bieber and in 1808 was one of the founding members of the Wetterau Society in Hanau . During this time he wrote some notable publications on mining.
