#MINERALMONDAY: Bismuth

#MINERALMONDAY: Bismuth

It’s not so common for us to think about pure metals as minerals, or even crystals, but just like pinocchio could be a real boy, pure metals can be minerals too. This is because, if the metal cools down from a melt very slowly, layers of metal atoms can add onto previously solidified atoms, forming a defined lattice of atoms, and ta-dahh, it’s a single crystal! This is different from m ...[Read More]

#MINERALMONDAY: Zdenĕkite, way too pretty to mine

One of the saddest things for mineralogists is to see beautiful minerals crushed to extract their valuable contents, but often, without mining, we don’t get to see these minerals in the first place. Mineral hunters often scrounge around in the big piles of waste rock from mines, because the machines used for smashing up rock do a much better job of exposing minerals than a geological hammer ...[Read More]

#MINERALMONDAY – we’re back with baksanite!

#MINERALMONDAY – we’re back with baksanite!

#MINERALMONDAY: your weekly dose of minerals every* Monday (* excluding the last few months of Mondays…). A lot of bad things have happened since the start of the year, but perhaps the least important of these is the complete lack of minerals every Monday. Don’t worry, we are back, and what better way to start than with baksanite, Bi6Te2S3. Why baksanite? Well, for the sake of sounding ...[Read More]
