The Franken­holz Mine – A Hid­den Chapter of In­dus­trial His­to­ryFrom early tunnel construction in the 18th century to its final closure in the 1950s, the Frankenholz Mine in Germany’s Saar region was a key site of coal mining history. With ambitious shaft projects, its own cableway connection to Bexbach, and remarkable geological features – including fossil discoveries and natural oil seepages – the mine reflects both the rise of industrial progress and the dangers of underground work. Gas explosions, water ingress, and tragic accidents shaped the lives of thousands of miners. Frankenholz remains a compelling reminder of a bygone mining era.

ZincIin 1546 Georgius Agricola reported about a white metal which is fused to the Rammelsberg lead and silver melter and that you could scrape off. He called this metal "contrefey", because it could imitate gold. Agricola did not recognize that this metal was zinc. He further observed that a similar metal, which he named from some unknown reasons "ZINCUM" arose under similar circumstances in Silesia during smelting.

Fal­tenEine durch Faltung entstandene Verbiegung oder Verkrümmung einer ehemals horizontal geschichteten Gesteinseinheit in allen Größenordnungen. Je nach Form unterscheidet man Knickfalten, Biegefalten oder Fließfalten. Die Faltenformen Sattel (Antiform) und Mulde (Synform) sind abhängig von der Mächtigkeit des verfalteten Schichtpaketes, den mechanischen Eigenschaften der Gesteine, dem Vorhandensein von Abscherflächen und auftretenden Spannungen.

Stone tum­bling - Our ex­pe­ri­encesWe do not thumble stones to get smooth and even things that look like the tumbled stones in the esoteric shops, but to discover the secret of the stone. We have thumbled stones in the spirator for years and have documented our experiences with stones, machinery, abrasives and polishing techniques. Our experience will help you to avoid errors and run approach to the subject.

Perl­proben... Man glüht in der rauschenden Flamme eines Bunsenbrenners ein Magnesiastäbchen bis zur Rotglut aus. Mit dem heißen Magnesiastäbchen wird eine kleine Menge Borax oder Phosphorsalz aufgenommen und vorsichtig in die Brennerflamme gebracht. Unter ständigen Drehen wird das Salz so lange in der Brennerflamme gedreht, bis eine klare Perle entstanden ist. Dieser Vorgang wird so lange wiederholt, bis eine Perle von ca. 4 -5 mm entstanden ist ... ein Beitrag von Andreas B.
