The central museum of our prefecture holds the exhibition of many useful minerals and rare ones during the summer holiday of schools. 
This is "pyrite" combined with iron (Fe) and sulfur (S). As people in old days saw its yellowish color and often thought this mineral was gold, pyrite was called "fool's gold". Pyrite has a cubic crystal system. I am always surprised at its artificial looking big cube.
Here you are. The is "natural gold nugget".
All gold medals at Tokyo Olympics were made from gold used in industrial components such as circuit boards and connecters. Is it possible for humans to discover or make a new element that is more beautiful than gold which was called "sweat of the sun" in the Inca Empire?
In this exhibition, I realized many ores contain sulfur. Have you ever seen this ore? Cinnabar (mercury sulfide) is combined with mercury (Hg) and sulfur (S). Chinese alchemy used this to make a medicine of perpetual youth. It is horrible to take a medicine of mercury.
In
In many countries, this reddish ore has been used to make a vivid vermilion pigment.
This looks like an interesting exhibit!
ReplyDeleteHow interesting and good to see. Thanks for sharing.

ReplyDeleteHello rtc, Minerals are so fascinating--you are lucky that your local museum put up this display. In Cleveland we have a natural history museum that in addition to dinosaurs and the like, also contains a Hall of Minerals.

ReplyDeleteDearest RTC,
ReplyDeleteMinerals are the most intriguing things on this planet.
They teach us many uses and stunning results when used after being mined.
Still proudly keep my gifted dark grey silver oxide with yellow pyrite in it: https://mariettesbacktobasics.blogspot.com/2021/07/historic-town-of-guanajuato-mexico-and.html

I'm very fond of minerals, and I keep some beautiful pieces at home. I believe they give us energy.
ReplyDeleteI would like to visit such exhibition as the above mentioned.
Beautiful. Greetings.
ReplyDeleteI have a rock collection with some of these, they are fascinating!
ReplyDeleteEducational
ReplyDeleteThis looks fascinating. A good friend is very into collecting crystals and mineerals -- he would love this. Thanks for coming by my blog the other day!
ReplyDeleteI see that you are interested in minerals. If at any time you travel to Argentina, I invite you to visit the open pit mine in Wanda, province of Misiones-Argentina. For the moment I leave you a page for you to read about them.

Seeing the minerals are good. I saw some interesting items while looking at a few jewelry items in Alaska. Some were made from fossil tusks or antlers. Have a good day.
ReplyDeleteYes, we know about "fool's gold" here in California. When pioneers came to the west panning for gold, they often came across this fool's gold. It sometimes appeared as little flakes in the water. The natural gold nugget at the museum is very pretty, isn't it?

This looks a good exhibition.
ReplyDeleteThank you for sharing these photographs.
All the best Jan
I think all minerals are interesting of their form and ingredients, RTC. The gold is special one, I saw some of things made of gold in the Hermitage, my city famous museum.
ReplyDeleteThanks for sharing!
Beautiful blog
ReplyDelete謝謝分享🙏
ReplyDelete"The Exhibition Of Minerals" is awesome 👍
We also visited the mineral museum this year. Amazing wonders of nature can be seen there.
ReplyDeleteI liked your comment today on my post, "leaves on the ground are good friends of young children."
ReplyDeleteThat's so true, and I remember my own kids playing in a pile of leaves at their grandmother's house.
I've been trying to find that picture, and still looking for it. Your quote should be there for all
to see. : )
Have a sweet September weekend.
