Cornelio August Severinus Doelter

He conducted pioneering experiments in synthetic mineralogy and petrology by melting down rocks and allowing recrystallization of mineral constituents.

He was influenced by his teachers Robert Bunsen, Johann Friedrich Carl Klein, Ernst Wilhelm Benecke.

His experimental work involved the synthesis of minerals at high pressure and temperature including nepheline, pyroxenes, micas, and zeolites.

He studied water of crystallization in the zeolites, examined the physical and chemical laws involved in silicate melting.

He later examined the physical properties of silicates and other minerals and suggested theories to explain the nature of electrical conductivity by crystals.
