The Mineralogical Museum's mineral collection contains minerals, gemstones and precious stones as well as syntheses and imitations of minerals. The collection provides the basis for mineralogical research and teaching at the University of Hamburg. It has grown since 1988 from about 1,600 to date (2022) about 3,155 of the currently approximately 5,800 recognized mineral species, making it one of the largest mineralogical reference collections in Germany. In the context of geodiversity research, numerous new minerals have been scientifically described in the Mineralogical Museum and are deposited in the museum as so-called type minerals.
From this collection a total of 32 digital objects are displayed in FUNDus

Ulex, G.L. (1848)
(Liebig) Annalen der Chemie und Pharmacie , 66 , 41-44 Notes / Further information: During foundation work at the St. Nikolai church in Hamburg, Germany, numerous crystals were found in a brownish-black layer of peat-soil in 1846.
The crystals were examined, described and named in honor of Minister von Struve by the chemist/pharmacist Georg Ludwig Ulex (Hamburg, 1811-1883).
