This holiday season, why not get a mineral every day instead of chocolate? Today’s mineral is Uraninite find out more about it below..
As we move towards the 25th of December, the number of shopping days decreases – and you might be out searching for the perfect gift! Sticking with the vintage holidays you might decide to get a vintage festive gift for a friend or loved one and when shopping in antiques stores or vintage fairs there is one thing that is often hard to miss, and that is the lurid yellow-green glassware often called Vaseline Glass (due to it’s similarity to the jelly).
However the interesting thing about this glass and the reason it is such a bright colour, is that it was made with the radioactive element uranium (leading to it’s other name – Uranium Glass), and the uranium came from the mineral Uraninite (also called Pitchblende). Don’t worry – the level of radioactivity is so low that it is generally considered harmless, and some people love to collect this glass for it’s historical value – so it could turn out to be an interesting talking point as a gift for that vintage lover in your life!
