Growth phenomena on crystals
Lecture by Dr Paul Rustemeyer on 16 October, 6.30 pm at the TIETZ
On Wednesday 16 October at 6.30 pm, interested parties are invited to a lecture by Dr Paul Rustemeyer on the topic of "Growth phenomena in crystals - skeletal crystals and dendrites" in the Tietz event room (3rd floor). Admission is free.
Why do snowflakes look the way they do? What determines the internal structure of crystals? Chemist and mineral photographer Dr Paul Rustemeyer will answer these and other questions about growth phenomena in crystals.
He presents attractive and interesting crystal phenomena that he has photographed himself in numerous private collections and museums. For example, he presents the funnel-shaped skeleton crystals of the dazzling mineral bismuth, the sceptre crystals and window formations on quartz, as well as the bizarre crystals of the commonplace "fleur de sel". The speaker also sheds light on the formation of special crystal formations.
Appropriate sounds accompany the colourful illustrations, turning the evening into an audio-visual experience.
Of regional interest are his explanations of the tourmaline skeleton crystals from the Wolkenburg and Amerika sites in the Mulde Valley and Irfersgrün. Anyone who would like to try their hand at crystal growing after the lecture will receive very practical information on this during the talk.
Dr Paul Rustemeyer will also be available to answer individual questions after the lecture.
