Carl Friedrich Wenzel
Carl Friedrich Wenzel (also written as Karl Friedrich W. ) (born August 20, 1740 in Dresden , † February 26, 1793 in Freiberg ) was a German chemist .
Live and act
He first learned in his father's bookbinding workshop, where he also worked as a journeyman. In 1755 he began to leave his hometown and went on several journeys that also took him to Greenland . He completed training as a ship surgeon in the Dutch service. In 1766 he began to study chemistry in Leipzig for three years. In 1780 he became a chemist with the electoral Saxon smelting administration, later in 1785 chief hüttenassessor in Freiberg and from 1786 arcanist in the porcelain factory in Meissen . There, improvements to the underglaze cobalt blue (see glaze ) are attributed to him.
Along with Jeremias Benjamin Richter, Wenzel was the first to deal with the problem of chemical kinship theory, the doctrine of the kinship of bodies .
"The strength of the chemical relationship is proportional to the mass of the active ones."
In this work he anticipated the law of mass action . According to this, the chemical action of a body is proportional and dependent on its reactive or effective amount or its concentration .
