Borax:
- A borate mineral
- Forms in evaporite deposits
- Turns opaque when it dehydrates
- Has many industrial uses, e.g. cleaning products, pH buffer, gold extraction
- Its name comes from the Arabic word "بورق/bauraq" (white) #minerals
Two white, rectangular borax crystals stacked on top of each other. Their surface has a powdery appearance. From Little Borax Lake, California, USA.

Specimen on display in the Natural History Museum, London. A group of white tabular borax crystals on white and grey clay. From West Baker Mine, California, USA.

Ahh I wrote & illustrated my first book!

It’s been a secret I’ve kept for over a year, but very excited to finally reveal ROCKS – published by @quartobooksuk.bsky.social in March 2026!

You can pre-order from all the usual places here: geni.us/Rocks

#SciArt #PortfolioDay #illustrator #BookSky
A beige book cover with a grey rock in the middle cut by white streaks. The title says ROCKS, below, the subtitle is A Guide to the Stones Around Us and the Stories They Tell, Vojta Hybl. Illustrations of rocks surround the cover.

Spodumene:
- Silicate mineral
- Forms in lithium-rich granite pegmatites

Pale green-grey opaque spodumene prism in a white pegmatite. From Ravensthorpe, Western Australia.

Specimen on display in the Natural History Museum, London. A large, pale pink and translucent chunk of kunzite, a variety of spodumene. From Urupuca Mine, Minas Gerais, Brazil. This information is repeated on the display label.

Analcime:
- A silicate mineral
- Also known as analcite
- Forms in basalt
- Its name comes from the Greek word "ανάλκιμος/analkimos" (weak), because it develops a weak electrostatic charge when heated (pyroelectric) or rubbed (piezoelectric) #minerals
Large white crystals of analcime. From Bowling, West Dunbartonshire, Scotland, UK.

I hear and see your concerns. Over the weekend, a couple users hosted on Blacksky's PDS were banned from the Bluesky app and thus the Bluesky API servers. This was a weakness of our system I've been aware of and hoped we had more time to address before any kind of public incident. 1/11
