Please drop a note to hastagmincup@gmail.com for details.
Thank you!

I've only ever worked on my birthday once in my entire life 😂 I always take it off and the days before/after
Likely lots of other trace elements depending on what's dissolved in the water: www.usgs.gov/news/geysers...
A piece of beige geyserite in my gloved hand. It's about 13cm long and has a weird convulated surface, very wrinkly like a brain. From the Natural History Museum, London's collection.
This is your brain on #minerals
A specimen of geyserite (a type of siliceous rock that forms around hot springs and geysers) from Fire Hole River, Yellowstone, USA
No, tufa is different and is made of carbonate

I am apparently locked out of my main bsky account @bowlerhatscience.org (permanently?), so I've made this alt. I can prove it's me but I really don't wanna *have* to do it.
Some discussion on Artemis II broadcast about how dark the Moon is compared to Earth. Here's a really nice look at the two together from the same camera -- the Moon isn't white, it's dark brown www.planetary.org/space-images...
Long vertical quartz crystal with a transparent pyramidal top. The bottom is milkier with jagged edges. It sits on a metal mount on a frosted plinth in front of a grey background. At the Royal Ontario Museum.
Happy Geologists’ Day!!! Geology is for everyone, especially those who love cool rocks and minerals like this quartz!!! #GeoscienceBluesky #GeologistsDay
Deep purple blue nitrile gloved hand holds translucent slide of obsidian. It looked like dark Smokey glass with black flowy bands across with a small patch of red. It’s held above a white tray on a black background. At the Canadian Museum of Nature.
I just saw that it’s Geologists Day today!!! To share my excitement about geology, here is one of my favourite types of rock: obsidian!! This is a thin polished slice showing flow banding. #GeologistsDay #GeoscienceBluesky ⚒️🧪
I still have a fair amount of Parma Violets left but I'm getting ready for round two 💕
On the left, a piece of lumpy crystalline pyrite. On the right, a twinned pyrite cube. They both have eyes and mouths drawn on them. The one on the left also has a pirate hat, a dagger and looks angry. Its speech bubble says , "Arrr! It's a pyrite's life for me!" The pyrite cube on the right looks worried and replies, "You fool! You'll never find any gold!"
Happy April Fool's Gold Day! #minerals #GeologistProblems
Oh cool, thank you! Let me know when you're coming

That one scene in Sinners (2025)
Harry Potter tattoo regret rate is an order of magnitude higher than regret for Gender Reassignment Surgery and yet no one has been brave enough to suggest we legislate Harry Potter tattoos.
The head and shoulders of a big cat, a cheetah or a leopard, sculpted from an unusual stone which is mottled yellow and white.
Just the stone to carve a cheetah 🐆! Anna Maria Massinelli’s new book on the use of the decorative stone Giallo tigrato is available to download at www.academia.edu/165293968/Pa... #decorativestone
