Family tour: Night-time in the museum

16 November 2022 – 4 February 2023, Saturdays 6 pm

Equipped with headlamp and UV flashlight, you can explore the terra mineralia darks.

During an exciting tour of the dark exhibition, families observe which mineral fluoresces in which color. In addition, selected minerals are irradiated with ultraviolet light in a special room in the exhibition – the "Journey into Light". "This part of the sunlight has such a high energy that it causes sunburn in humans; but it stimulates some minerals to a special glow," explains museum educator Christina Seifert.

In the hands-on laboratory "Research Trip", the girls and boys can then get to the bottom of the phenomenon of fluorescence. In various experiments, the employees explain what light actually consists of, where the ultraviolet light, which is invisible to humans, comes from and which other forces can also trigger a glow.

"Incidentally, the effect of fluorescence is named after the mineral fluorite. The phenomenon was also researched at the TU Bergakademie Freiberg, for example in 1824 by Professor Friedrich Mohs," adds the museum pedagogue.

In the pre-Christmas period until 21 December 2019 and in the New Year until 1 February 2020, a very special excursion to the museum awaits visitors of all ages. Equipped with a head lamp and UV torch, they can explore the terra mineralia in the dark from 6 p.m. on Saturdays. Among other things, you can discover fluorescent minerals that glow in all colours.

This special phenomenon is called luminescence. In terra mineralia you can marvel at the "glow" of minerals in a specially made room - the "journey into the light". There selected minerals are irradiated with ultraviolet light. This part of the sunlight has such a high energy that it causes sunburn in humans; some minerals, however, it stimulates to a special glow. During the exciting tour through the dark exhibition, the families will observe exactly which mineral fluoresces in which colour.
