The Gallery of Historic Ores displays a selection of ores, i.e. rock and mineral specimens of economical interest, as well as mining memorabilia. They are arranged by chemical element. As of March 2016, elements considered are aluminium, beryllium, carbon, copper, iron and tin. All rock and mineral specimens were deaccessioned from collections of historical importance.
The Gallery of Historic Crystals is currently under construction. The three sections (Chemistry, Physics and Lore of Crystals) will be completed over the coming months.
