I’m back to uploading more of my The Hidden Land collection.
These were also taken from the Australian Museum’s collection of rocks and minerals; the handicaps and limitations of the shots are the same – behind glass cases and limited lighting. As before, this collection features rocks and minerals highlighting their unique properties and formations. I always try to take as macro a shot as I can without loosing too much information about my subjects. Some post work was needed to bring out the textures and balance the lighting – Tone Curve, Saturation and Gamma.

Stolzite is a mineral, a lead tungstate; with the formula PbWO4. It is similar to, and often associated with, Wulfenite which is the same chemical formula except that the tungsten is replaced by molybdenum. Lead tungstate crystals have the optical transparency of glass combined with much higher density (8.28 g/cm3 vs ~2.2 g/cm3 for fused silica). They are used as scintillators.
Discovered in 1845 it is named after Joseph Alexi Stolz of Teplice in Bohemia.
