philbilly333 Day 48 of #100DaysOfGeology : White!

The color white comes from the mineral Cerussite, which used to be used for cosmetics (like powder) in the Victorian ages. But like the rest of #RainbowWeek the mineral Cerussite is (naturally) terribly poisonous. It's also known as "White lead." So in the Victorian period, people would put a white powder on their faces that was incredibly toxic and that could have potentially disfigured their skin!

philbilly333 Day 47 of #100DaysOfGeology : Blue!

This distinct blue, or Ultramarine as it's better known for, is a color that comes from the mineral Lapis Lazuli, from the Sodalite mineral group.
Lapis had a very important history as Ultramarine was a very valuable pigment, usually reserved for rich people or for important paintings. An example is that ultramarine was usually used to color the Virgin Mary's robes.
Part of the reason it was so expensive is that it was only found in small remote parts of Afghanistan.
Today it is widely used in jewelry because of its beautiful blue color.
This has been another post for #RainbowWeek in support of the LGBT+ community.

philbilly333 Day 46 of #100DaysOfGeology : Green!

Continuing #RainbowWeek, today's color is green! The pigment green comes from several colors, but the main two are diopside and malachite.
Diopside was used a lot in Russia, as that was a common mineral in Siberia, and it was used mainly to decorate religious icons.
Malachite, the green mineral that is seen in the photo above, was carved into objects and used to decorate floors in Russian mansions.
I actually took the photo above of a large vase made of malachite when I was visiting a museum in St. Petersburg this summer.
Special shoutout to @zyoodin because why not?

philbilly333 Day 45 of #100DaysOfGeology : Yellow!

Continuing my #RainbowWeek while supporting #AlliedInGreek , today's color is Yellow!
The pigment was first used by crushing down the mineral Orpiment, a yellowish-orange mineral. This pigment was used by the Ancient Egyptians in their art, and it was also used in cosmetics.
However, the bad thing about Orpiment is that while it produces a beautiful, vibrant color, it is also an Arseno-sulfide. Meaning that it is an Arsenic bearing mineral. In fact, it is THE Arsenic ore, as it contains more molar arsenic than Realgar, the other common arseno-sulfide.
In the photo below, you can see some of the yellow color that was probably created by ground-up Orpiment in the skirts of the two figures on the right and the skin color of the figure on the left.

philbilly333 Day 44 of #100DaysOfGeology : Red!

This week, in honor of #AlliedInGreek I wanted to do something a bit different. I wanted to do a #RainbowWeek where I named 7 colors, the minerals that were used to make them, and some other fun facts that go along with that.
So for day 1, we'll start at the top of the rainbow with Red!
The color red can come from two different minerals: Hematite or Cinnabar.
Hematite was used by the "cavemen" in cave paintings, as seen above. Cinnabar, a Mercury containing mineral, created the color Vermillion, which was used for Imperial writing in China.
