Also, the museum houses the world's most extensive collection of mineral properties exhibits. These "push-button" electro-mechanical exhibits demonstrating dozens of the electrical, optical, and physical properties of minerals and materials such as fluorescence, radioactivity, magnetism, conductivity, flexibility, triboluminescence, piezoelectricity, double refraction, resistivity, and much more. Other displays include a collection of more than 100 mine safety lamps and scientific instruments and specimens belonging to Frederick Augustus Genth, the famous mineralogist. The museum serves both as a teaching tool for University courses and as an educational institution, bringing to the general public an appreciation for minerals, mining, and the materials sciences.
