Heinrich Gottlieb Kühn
His parents were the senior consistory councilor Carl Gottlieb Kühn († 1826/36) and his wife Sophia Heym (1757-1822), a daughter of the Dresden merchant Carl Heinrich Heym . The geologist Carl Amandus Kühn was his older brother.
From 1804 Kühn studied mining science at the Bergakademie Freiberg , law in Wittenberg and chemistry in Berlin . As a mountain trainee at the mining authority in Freiberg , he was also involved in the geognostic state survey . In 1814 Kühn became inspector of the technical department of the Meissen porcelain factory and at the same time a member of the administration. There he introduced round and deck ovens, with which the burning capacity could be quadrupled. Kühn invented chromium oxide green as a new underglaze color in 1817 and the method for shiny gold plating, which was first used in 1827 . In 1837 Kühn developed the Schiller or luster colors , which were widely used in the ceramics industry. On October 1, 1849, he was appointed director of the porcelain factory. He held this position until his death. Kühn also designed the new manufacturing facility in the Meißen Triebischtal and managed the move from Albrechtsburg from 1863–65 .
Another Kühn invention in 1846 was the so-called fire extinguisher bomb , which was patented as a Kühn fire extinguisher box. The contents of the can, a mixture of saltpeter , sulfur and coal , were made to react using a fuse and thrown into the fire. The principle was based on the fact that the fire should be deprived of oxygen through the development of larger quantities of sulfur dioxide . In addition, he developed Kühn's Chili Explosive Powder.
In 1816 he married Caroline Wilhmine Neumeister in Brockwitz near Meißen, a daughter of the general excise inspector Johann George Neumeister . The couple had four sons and five daughters, including:
- Robert (1818–1874), mountain manager and mine director in Zwickau
- Otto (1823–1876), mountain manager of the Zauckerode hard coal works near Dresden
After the death of his first wife, he married Auguste Ernestine Schneider , the daughter of the war chancellery secretary Johann Gottfried Schneider, in Weinböhla in 1833 . The couple had a son and a daughter.
