RE: https://mastodon.social/@MineralCup/117300422731472297 ngl I'm voting #Stichtite to get back for what happened to #Asagiite (also, it's kinda cool in its own right—just like asagiite!) #MinCup26#JusticeForAsagiite

#MinCup26 Round 2 Match 4 Both colourful yet opposite in almost every other way, it’s abundant and hard #Quartz against rare and very soft #Stichtite. VOTE: https://www.mineralcup.org/2026/vote-results/vote-r2m04 RESULTS: https://www.mineralcup.org/2026/vote-results/results-r2m04

Anthorite can be found in lunar & cometary rocks, but Sphalerite gets my vote with cool optical/electrical properties & its role in art history as main zinc ore. Zn has been used in brass & bronze for centuries. Since the 18th century it was used to make ZnO pigments & etching, plates. 🧵1/2 #MinCup26 #scicomm #artHistory #minerals

Winning by just 11 out of 1705 votes, primary mineral #Skutterudite is continuing on to represent cobalt and arsenic in #MinCup26 Round 2. While beautiful and beloved, weathering product #Erythrite didn’t quite make it.
