Identity HelpLocation help: Johan Friedrich Gr., Koen, Baden-Wurttemberg
7th May 2012 18:47 UTCVik Vanrusselt Expert
I bought a specimen of Beyerite at the Minerant mineral fair in Antwerp yesterday.
The location on the label is: Johan Friedrich Gr. Koen, Black Forest, Baden-Württemberg, Germany.
I can't find this locality on Mindat, any ideas?
Thanks,
Vik

is "Grube Johann-Friedrich" see "Mineralfundstellen Baden-Württemberg" M. Glas/H.Schmeltzer 1977:
"Königswart" at last was named "Johan-Friedrich" from 1823-1825.

I found a reference to the mine in "Beyträge zur Geschichte des teutschen Bergbaues" (1783) by Johann Friedrich Gmelin:
http://books.google.be/books?id=9yQ7AAAAcAAJ&pg=PA428&lpg=PA428&dq=%22k%C3%B6nigswart%22+%22grube+johann-friedrich%22&source=bl&ots=muafOhPGZf&sig=I75j0I00y7vjdWZ0nAvBsGqr3tE&hl=nl&sa=X&ei=MdSqT8CZE4SZ-wbvj4mdCg&sqi=2&ved=0CDIQ6AEwAg#v=onepage&q=%22k%C3%B6nigswart%22%20%22grube%20johann-friedrich%22&f=false
Translation:
The Johann Friedrich Quarry or the old Königswart in the Murg Valley, not far from the village of Roth in the "Klosteramt" (i.e. an administrative division centering on the estates of a dissolved monastery) of Reichenbach, was, already under Duke Friedrich, known for it's beautiful copper and rich silver ores.
In 1739, from this mine and the mines S(aint) Peter and S(aint) George, 57 Zentner (1 Zentner is 50 kilograms) and 55 pounds were molten. Per Zentner, these ores from the last mine contained 1 loth (approximately 16 grams) of silver and 4 pounds of copper.
And from 17 1/2 Zentner gathered together from all of these mines came 150 pounds of rock and 59 pounds of iron-bearing chalk.
