#mineralcup2023 — Public Fediverse posts

How, you might ask, does a perfectly formed #zircon get into a sapphire?

Sapphire melting temp: around 2030 °C. (wikipedia)
Zircon melting temp: high melting point (over 2500°C). (https://www.ga.gov.au/education/classroom-resources/minerals-energy/australian-mineral-facts/zircon)
Tiny zircons can withstand a lot of what makes and destroys other minerals.

Just leaving this here. Zircon and monazite. You're not going to see calcite in a sapphire, it couldn't take the heat.

This poem was inspired by my work in the geology labs of the University of Edinburgh when I was analyzing rock samples from Iceland. The procedure requires the rocks to be remelted at 1100 C so they can be poured into molds and shaped into glass disks. These disks are used for XRF and XRD analysis to understand the crystal structure of the rock and to see the element contents.

Corundum is an incredibly useful material for calibrating powder x-ray diffractometers, and you can get NIST SRM 1976c for this purpose.

it is also heavily used in making high temperature sample holders and about a billion other applications in science and chemistry.

vote corundum

Mineral friends, friends of minerals? enjoy some photos: #dioptase and #crocoite from Carnegie Natural History Museum.

My glee that @MineralCup is over here ehehehehe!

(Tho with split presence I do see why they're trying to hold voting on their website this year.)

#mineralcup2023 is almost here!

Don’t want to miss a second of the best event in social media, #MinCup23 ? Me either! Starting September 1st, search often for the hashtags #MinCup23, #MineralCup2023, #MinCup2023.

Also, you can make a #List and add @MineralCup to it. You will be notified whenever they post! I used Tooot to create a list, then added Mineral Cup to it. In the image below, you can see my Twitter Tooters list that I have added Mineral Cup to by using the 3 dot dropdown in the upper right corner and selecting “Add to List” (in Toot, I think). Cheers and see you for Mineral Cup in 16 days!

PS Use the link in the post quoted below to nominate your favorite mineral and vote for a comeback contender!
