正长石（双晶）（来源：弗赖贝格矿业学院） 德国巴伐利亚上弗兰肯的菲切尔山脉 - 高度: 3.2 cm - 闊度: 2.5 cm- 23 g
Watch a video of this specimen by following the Vimeo link below: https://vimeo.com/1139863437/dcdcc8fd84
The famous mining academy in Freiberg, Germany was founded in November 1765 by Prince Xavier of Kursachsen, and its mineral museum was founded at the same time, probably based initially on the collection formed by C.E. Gellert (1713-1795). In 1767 the Academy established its own mineral dealership (Niederlage), probably for the purpose of supplying students with study specimens for their own collections.
(Mineralogical Record biographies page).
Here is a sharp, textbook orthoclase featuring penetration twinning from Fichtelgebirge (Fichtel mountains) at the German-Czech border!
The label and box from the Bergakademie this specimen comes from probably dates back to the late XIXth century or early XXth century.
Ex coll. Bouzat
