Karl Wanek from Gloggnitz found almost all of his roughly 5,000 specimens himself – in alpine clefts, old mines and abroad. Johann Zenz portrays one of Austria's most important collectors and his partner Renate Kain.

At a time when a large part of the acquisition and “collecting” of minerals and crystal specimens is carried out via the Internet and often at almost unimaginable sales prices, the species of those who still track down and mine their specimens themselves in nature seems to be disappearing. Karl Wanek from Gloggnitz in Lower Austria is one of the most important Austrian collectors who has actively worked on numerous regional and international sites for almost 60 years.

The first contact

Karl Wanek was born in 1944 and grew up in a difficult time in Hirschwang in southern Lower Austria. Although this region has a long mining tradition, finds of really high-quality minerals are a rarity. Nevertheless, interest in these beautiful natural products soon awoke and an alpine garden was soon set up with the first stones he found himself (copper ore, malachite, azurite).

School lessons were not necessarily one of his favorite pastimes. When he was once again forced to spend an extended period of time in the natural history cabinet, he discovered a sparkling rock crystal in the school mineral collection, which soon adorned his alpine garden.

After marrying at a very young age and the birth of his daughter, he took his first major vacation in Zell am See in Salzburg in 1966. In the breakfast room of the accommodation there was a cabinet with magnificent local crystals that immediately fascinated Karl. In the days that followed, he was able to find his first alpine minerals such as actinolite, small quartz crystals, epidote and adular on the Kitzsteinhorn mountain. This sparked his enthusiasm for a lifelong interest in beautiful stones.

A perfect symbiosis with life partner Renate

In the years that followed, further collecting tours repeatedly yielded beautiful finds. As he didn't have his own car, he usually had to use a moped as a means of transportation. The destinations were therefore limited to local occurrences in Lower Austria and neighboring Styria province. The former large magnesite mine in Veitsch, Styria, exerted a particular attraction here, which became the regular destination of around 140 (!) collecting trips over many years and often rewarded perseverance with beautiful aragonite specimens, magnesite and quartz crystals.

However, it was his acquaintance with Renate Kain, who was also very interested in minerals and whom he finally married in 1995, that really ignited his collecting turbo. Over the course of 30 years, he has undertaken hundreds of mineral tours and numerous trips with her, including to foreign sites. Renate is the perfect companion for Karl and was also able to discover and recover numerous beautiful stones herself on their joint collecting excursions.

Mines and high alpine terrain

In addition to the local sites, alpine minerals soon became the focus of his collecting interests. Fortunate encounters with “instructors” such as Kurt Nowak and Toni Zlöbl from Gastein, Salzburg, led him to excellent finds of his own: Quartz crystals up to 75 cm in size and outstanding adularia from the Ortberg in the Gastein Valley, Salzburg, beautiful crystals from …
