(11.02.2022) Minerals for the MiMa. The association of friends of minerals and mining received a generous donation for the MiMa from the family of the hotelier Junghanns. Members of the association were able to bring collection pieces of minerals to the museum with several car transports. In the regular work assignments of the mineral friends, the minerals are recorded either for the exhibition, the archive or for sale. The sales proceeds can be used to finance measures to increase the attractiveness of the museum.
The collected treasures come from the inventory of the deceased hotelier Eberhard Junghanns. As a member of the association, he had regularly supported the museum and was enthusiastic about minerals. This is also shown by the fact that he exhibited minerals from the Oberwolfach Clara mine in a showcase in the hotel lobby.
The association is very grateful to the Junghanns family for this support of the museum, which shows unique treasures from the Black Forest. (Picture: Eberhard Junghanns with his son in front of the showcase in the hotel lobby.)
(20.09.2021) Presentation of minerals in 3D. There's a new attraction at the MiMa: A 3D television was installed next to the staircase to the upper floor, on which a 20-minute three-dimensional slide show of minerals from the Clara mine is displayed. The visitors experience a fascinating view of the small minerals on the large screen with the attached 3D glasses. Dieter Grässer, who photographed the minerals and programmed the presentation, made them available to the museum, free of charge.
(20.09.2021) Oberwolfachit - a new mineral. In April 2021, a newly discovered mineral from the Clara pit was named "Oberwolfachite" by the IMA (International Mineralogical Association). The original material is kept in Moscow. The Association of Friends of Minerals and Mining in Oberwolfach was able to purchase a small piece from the finder for the MiMa. Unfortunately, due to its small size, it cannot be exhibited. However, other minerals that are named after the region can be found in the museum. The minerals Claraite, Rankachite and Benauite are displayed in the micro showcases, among many others.
(27.07.2021) Book publication "Museum ohne Grenzen" ("Museum without Borders"). 345 museums in three countries - from Bern to Mainz, from Stuttgart to Metz and Nancy - can be visited with the Upper Rhine Museum Pass.

In 3 volumes he guides the reader through 160 museums in Germany, Switzerland and France. Our museum is also among the writer's discoveries. In addition to a description from his point of view, he presents a short story inspired by the museum under the title "Die gelbe Null" ("The yellow Zero")! The 3 volumes were published by Herder Verlag in 2021 (ISBN 978-3-451-39189-7).
