GLASSY WONDERS is the first book to describe natural glasses (of volcanic and impact origin) worldwide and in our galaxy. From Antarctica to Vietnam, from Jupiter to Mars, over 313 specimens from 374 locations in 91 countries around the world and on 3 planets are described (based on occurrence, history, geology, etc.) and presented with full-page photos. In addition to well-known tektites such as moldavite and indochinite, many impactites unknown outside the geology community are also presented. Text contributions come from experts in this field: Christian Koeberl (Impact Researcher/Former General Director of the Natural History Museum Vienna, Austria) and Aubrey Whymark (Tektite Specialist, Senior Wellsite Geologist and Geosteerer, Manila, Philippines). The book GLASSY WONDERS (210 pages) is published in English, limited with 500 copies and available worldwide. Publisher: Der Konterfei Vienna, 2025.
