Viele der Gesteinsproben

The focus of the interdisciplinary research project was not only the exact mineralogical determination of the individual stones and their geological origin, but also the comparison with material from the historical holdings of Saxon mineralogical collections. As it turns out, many of Taddel’s stone samples later came into the possession of the court jeweller Johann Christian Neuber (1736 – 1808) and were used in his works of art. After Neuber’s financial bankruptcy in 1794, many pieces went to the mineral depository of the Freiberg Mining Academy and from there to the collections compiled by the co-founder of mineralogy Abraham Gottlob Werner (1749 – 1817). Others were preserved in various private collections and then came to the Dresden Mineral Cabinet. In comparison with Taddel's stone cabinet, it has been possible to identify previously unnoticed museum objects and to reunite pieces that were once cut and made from the same stone samples after more than 200 years.
