Flowers of Iron

The flowers of iron were found in the siderite cavities at Erzberg. An illustration of the decorative, ramified calcium carbonate mineral aragonite, which is usually snow-white, was published as long ago as 1642 in Michael Besler’s “Cabinet of Remarkable Minerals”. Porters carried the large fragile pieces from Eisenerz to Vienna on foot in panniers. The beauty and quality of the specimens from Erzberg are still considered unique.
The specimen (from 1875) is on display in Hall I.
