Two stick characters, Cueball and Ponytail (wearing a ponytail) are talking. [Ponytail and Cueball are talking. Ponytail has her hand raised, palm up, towards Cueball.] Ponytail: Silicate chemistry is second nature to us geochemists, so it's easy to forget that the average person probably only knows the formulas for olivine and one or two feldspars. Cueball: And quartz, of course. Ponytail: Of course.

Big step forward in cleaner aluminum, which should be a huge winner given lower OpEx, improved health and safety, and retrofit capability.

Combine this with new, cleaner ways to get alumina from silicate rock, and Al is a material of the future

Research and development of CO₂ removal (CDR) should be a government-led effort, but all the people who were experts in various aspects of CDR in the US government are gone.
David Ho, a professor of oceanography at the University of Hawaii, says that firings and the cutting of funding have had significant impacts on further developing CDR techniques, which include machines that suck CO2 out of the air, referred to as direct air capture, and the concept of reducing the acidity of the ocean so it will naturally absorb more CO2 than it already does. Roughly 22 million tons of carbon dioxide already find their way into the ocean every day, and reducing the ocean's acidity helps naturally increase those numbers. This can be done by grinding up silicate rocks and introducing them to the ocean. "When they fired a whole bunch of people - the indiscriminate firing of people - these carbon-dioxide removal efforts were fairly nascent, and so a lot of the people were

In very rough numbers, it will take something over 50,000 years for half of the excess CO2 left in the atmosphere at the time of net zero to be removed from the atmosphere. That's a rough number because modelling the slow process of silicate weathering is tricky, but the general

Phenakite:
- A silicate mineral
- Forms in pegmatite veins and mica-schists
- Sometimes used as a gemstone
- Its name comes from the Greek word "φέναξ/phénax" (deceiver) because it looks like quartz #minerals
A very elongate prism of cream, opaque phenakite. From Kragerø, Norway. Specimen on display in the Natural History Museum, London.

I can have 3 meals, Everyday, and when i spent 1% of it, i will probably be only person with Y chromosome if i still exist.

GOT: Jack Perry

Real Bat-Glass. Cry me a Bat-River.

I’m basically caught up on wrestlers now. I’m not buying any Fed toys unless they’re a cheap Ultimate of an undisgraced Legend and those are few and far between.

Why the Batmobile? It’s my only car.

On the entrance stage of All In London 2023, Jack Perry (Jazwares AEW Unrivaled 18) points at the Batmobile (Batman ‘66) where Hook (Ringside Exclusive) is sprawled across the hood being attended to by Aubrey Edwards (AEW Real Scale Ring Pack-In). He’s pointing at the windshield, presumably describing hau authentically silicate it is and what you can do about it. In the entranceway, CM Punk (Some Old-Ass Elite Version) is shaking his angry old man fist at the audacity of it all.

this comic is just evergreen i think
two stick figures discussing something, the one on the left saying "Silicate chemistry is second nature to us geochemists, so it's easy to forget that the average person probably only knows the formulas for olivine and one or two feldspars." The stick figure on the right responds "And quartz, of course." to which the one on the left agrees "of course." Below is text reading "Even when they're trying to compensate for it, experts in anything wildly overestimate the average person's familiarity with their field."

Thank you! It’s done with sodium silicate. It’s all a matter of playing with the wall thickness, application and timing 👌

Most zircon (zirconium silicate) still comes from mineral sand mining, and that's mostly in Australia and South Africa. So yes of course, Chinese zirconium comes from Australia, including the tiny amount used in sophisticated missiles. What a gigantic beat-up.

Any mineralogically inclined folks got any thoughts on this - I think the pink crystals in this shino are likely Rhodonite or something in that neighborhood (manganese silicate). The kiln effectively behaves as a contact metamorphic environment - cools very slowly from 1250C over 2 weeks.

I’ve not been much of a talc user but defo never used it since I became a petrologist. Not all actinolite-tremolite is asbestiform but there’s potential for it & other ‘asbestos’ minerals to be present. Talc itself is a silicate so risky as a powder. I’d give it a miss www.bbc.co.uk/news/article...
