In order to celebrate #Quartz' victory in #MinCup26 a 3D model is in the making (promised during round 1). It gets more complex by the unit and failing one connection will make it glass 😖. At this point very careful steps are being taken so progress is slow. Hopefully I will finish it on Sunday! 🤞🏻

Congrats to #Quartz, the literal bedrock of all minerals on Earth, after 10 years on the campaign trail it has got the #MinCup26 title. But a bigger congrats and thanks go to the @mineralcup.bsky.social team, for providing the sparkle we all needed to our social media feeds.

#MinCup26 er over og kvarts har endelig fått sin velfortjente seier! Takk for innsatsen og interessen, alle sammen, jeg vet organisatorene blir glade hvis vi fyller ut evalueringsskjemaet deres som er her. www.mineralcup.org/2026/players... Nå skal jeg gjøre noe anna ei stund, tror jeg!

En aller siste kvartspost før sengetid, for jeg må vise fram en Severdighet vi tilfeldigvis var og besøkte på campingferie i sommer: I Djúpivogur på øst-Island bor det 400 mennesker og én av dem er Auðunn. Auðunn har steinsag, Auðunn har utstillingslokale og Auðunn har en vanvittig teft for kvarts.
Skjermdump av facebook-sida til Steinasafn Auðuns / Audun's mineral collection, som er verd en kikk for den som har facebook. Utstillingslokalet er et stort åpent rom med hyller langs alle veggene, og alle hyllene er fulle av strålende fargerike steiner (mest varianter av kvarts og kalsitt) som Auðunn har funnet rundt omkring i terrenget og båret med seg heim med mye strev for å se om de ville bli fine ved oversaging. Open all year!

Hard choice again in #mincup26 finals, but I'm in for #Bergkristall (or #Quartz). Apart from its usefulness for time keeping its use in decorative goblets in the 16th century is fascinating mastery! Images from Fed. Art Collection Saxony: skd-online-collection.skd.museum/Result/Index...

There has been a lot of talk about piezoelectricity in the match, but little about exposure dating. Vote #quartz in #MinCup26 for the O2 atoms in the quartz crystal structure & the predictable way they are converted into beryllium isotopes when exposed to the Universe and not inside a mountain.

Det har vært mye snakk om piezoelektrisitet i kvartsfinalekampen, men for lite om eksponeringsdatering, syns jeg! Stem #quartz i #MinCup26 for O2-atomene i kvartsens krystallstruktur og den forutsigbare måten de gjøres om til berylliumisotoper når de er eksponert for Universet og ikke inni et fjell.

Mineralmåneden er over, kun siste match gjenstår. Alle mine gamle&nye favoritter på venstresida av kampoppsettskjemaet blei brutalt nedstemt etter tur (azuritt! Auripigment! Min evige yndling kalsitten! Steinsaltet som skulle til finalen!) så valget er lett: I dag blir det KVARTS for alle penga.
Ferdig utfylt kampoppsett med vinnere fra alle matcher i mineralkøppen (https://www.mineralcup.org/2026/bracket). Kupritt er finalist fra venstresida av skjemaet, kvarts fra høyresida.

Foreløpig resultat i semifinalen mellom kvarts og grafitt i årets mineralkøpp. Kvarts leder med 369 over 213 stemmer (men døgnet er ennå relativt ungt).

It has to be #halite for #MinCup26 ! You can make a laser out of salt droplets - place them on a superhydrophobic surface and the droplets are round and stable, making good laser cavities. web.archive.org/web/20111018...
Fig. 1 of the linked paper, showing the experimental setup, along with the broad-spectrum glow of the droplet, and the narrow spike of the laser spectrum. In the experimental setup you'll note that it took two lasers (a green one and an infrared one) to get red laser light out of the salt droplet.

Either could claim my art vote but of the two #Halite gets my physics vote. Plus it’s hard to quibble with being a necessity of life. It’s in blood, sweat and tears - and the sea! And then, there’s revenge for Orpiment. So I’m voting Halite! #MinCup26 #sciart
My “Blood, Sweat and Tears” lino block print is about how we as people reflect our origins in the ocean. Printed from 8 hand-carved blocks it shows blood cells racing through an artery (top left square), a cross-section of our skin with a sweat gland (middle left square), an eye with a tear (bottom left square) and a section of ocean seawater (vertical rectangle, right side, full height). Halite NaCl is part of all of the above.
