Silver – Day 11 of the Mineral Advent Calendar

This holiday season, why not get a mineral every day instead of chocolate? Today’s mineral is Silver find out more about it below..

Back on the vintage theme, if you decorated your tree you probably used tinsel, but instead of the multi-coloured garlands we think of today, until fairly recently, tinsel was the thin strands of shiny material you would drape all over the branches like hair!

This metal tinsel was probably made from lead, but in the 1600's tinsel was made from actual silver! This image is from Motherboard.

Using tinsel to decorate has been something that we have been doing for hundreds of years, but instead of the plastic types we think of today, tinsel used to be made of thin metal strips – and back in the 1600’s when tinsel was first used, it used to be made of actual silver (obviously this wasn’t decoration for the masses). And you can see, why – it’s very tinsel-ly just naturally. Though I imagine it tarnished pretty fast!

This silver is very tinsel-like. The photo was taken by Ian Jones.

Cerussite – Day 3 of the Mineral Advent Calendar

This holiday season, why not get a mineral every day instead of chocolate? Today’s mineral is Cerussite, find out more about it below..

One of my favourite things about this time of year is tucking up under a nice blanket with a hot chocolate and a seasonal film! And there are so many to choose from:

I love seasonal movies - have you watched Elf yet? WHY NOT!?! GO watch it as soon as you have finished this post!

I love seasonal movies – have you watched Elf yet? WHY NOT!?! GO watch it as soon as you have finished this post!

But in order to watch these cinematic gems (*excuse the pun) you need a nice shiny LCD television (or similar). If you want your TV functioning in full technicolor (even if you are watching a classic like ‘Christmas in Connecticut’) you need lead – and you get that from minerals like Cerussite.
