So it’s December the 1st and across the nation people are opening the first window of their advent calendars. But instead of chocolate, why not get a mineral every day?! Over the next 25 days I will post a new mineral related to an aspect of the holiday season for your enjoyment.
After all, what says mid-winter more than sparkles!
To kick us off, I’m looking at the first thing that most of us notice about the season – sparkling lights! It wouldn’t be winter without strings of glittering lights everywhere, but those lights wouldn’t function without tungsten, a metal found in the mineral Wolframite.
- Chemical formula: (Fe2+)WO4 to (Mn2+)WO4
- Colour: Greyish-black
- System: Monoclinic
- Hardness (Mohs): 4 – 4 1/2
- Can you find it in the UK? YES
Wolframite is one of the UK’s currently mined minerals, thanks to a new mining development that has recently started production just outside Plymouth in Devon. Tungsten is considered so valuable because of it’s resilience to high temperatures, which makes it ideal for use in many new technologies – including lights!
