Desert or sand roses are the bizarre minerals that are available in almost infinite sizes and shapes. But not only geologists are interested in these mineral flowers, but also tourists from Tunisia or Morocco like to bring them home as a souvenir. "NaturForm - Desert Roses and other" Mineral Blossoms "is the title of the corresponding special exhibition in Jena, which is open until 16 February 2008.

Visitors of all ages will not only get to see something in the new exhibition - they will also be able to participate. For example, they can study different types of desert sand under the stereomicroscope. "Large and small children are invited to feel different forms of gypsum crystals or to make crystal models, " explains Birgit Kreher-Hartmann, who works as a curator for the exhibition.

In addition to the diverse desert roses numerous other "mineral flowers" are exhibited. These are minerals that carry flowers or flowers in the name. These include near-surface formations in ores such as cobalt and nickel flowers. The coral-like formations of the snow-white iron flowers, which are created by leaching processes, are represented as well as hyacinths, rose quartz and straw stones. A certain holiday mood is certain when visiting the new special exhibition.

The exhibition can be visited on Mondays and Thursdays from 1 to 5 pm as well as by appointment. Guided tours for school classes, kindergartens and other groups are also possible outside these times. Please register by phone / fax 03641/948714 or by e-mail to:
