This holiday season, why not get a mineral every day instead of chocolate? Today’s mineral is Muscovite Mica find out more about it below..
Continuing on the theme of a vintage holiday season, another of my favourite things about this time of year is how much everyone embraces the sparkles!
In fact our love of sparkles isn’t a modern thing, even the Victorians like to embrace the glitter! But not having access to the plastics that we take for granted to make our sparkles, they had to look elsewhere, and found the amazing mineral Muscovite Mica. During the Victorian period, wealthy poeple celebrating the season would buy chunks of this mineral and then break it up to use the little reflective flakes as glitter, and if you have even been into a lab after a first year geology student has been doing their mineral identification – you will know that it still happens!! So today’s mineral is Muscovite Mica – vintage glitter.
Chemical formula: KAl2(AlSi3O10)(OH)2
Colour: White to colorless, silvery-white, and tinged various colors by impurities.
Hardness (Mohs): 2½
Can you find it in the UK? Yes
Mica is a common mineral that makes up many types of rock – you may be familiar with the dark brown to black version of Mica – Biotite – that you can see sparkling away in lumps of granite. Muscovite mica is also most easily found whe you look at a rock, rather than as big lumps of crystal, but you can still find it across the UK.
