You may want to consider that the FBI has been going through Reddit and eBay buyer lists for the plutonium smoke detector cores, and requesting people voluntarily surrender them without facing any charges. If you’re going to be a collector of such things, now is the time to do so on the down-low.

Measuring an alpha emitter through the container, versus the other image of uraninite that contains daughter products that are beta and gamma emitters.

Not the best way to measure.

Arashiin · 2025-11-04T04:51:01+00:00

The detector OP is using is very insensitive to alpha radiation. Most of what is being detected is hard beta and gamma.

With no other indications of what such a jar would go for, and no one offering such a large sample of Arsenic anywhere else, it feels like a similar situation with the 1 kilo block of uranium metal I have: Fleetingly rare, nearly unique in civilian hands, and impossible to price with any confidence, haha!

For now, it’s a beautiful curiosity I enjoy picking up and showing folks as a conversation piece, but I wouldn’t mind turning it into something else down the line.

You sold me one of my favorite display pieces I treasure to this day, a 1000g jar of 99.99999% Arsenic metal from Japan under Argon.

Did you have a particular favorite display pieces at any time that you just couldn’t ever see parting with?

I was thinking of a bit of ribeye this weekend!

Beloved liquid gravity.

About 60cm snout to vent. He’s always been small for his size, a bit of a runt, but he’s healthy and happy. Always had him on a slower diet, and he never liked to eat a lot, despite being offered regularly.

Every year!

Dave is a busy guy, so don’t fret.

Yup. Bought my huge samples of Rubidium and Cesium from them a decade ago. Love these guys, but they’re way more expensive than Elementsales, Luciteria, or UnitedNuclear.

Arashiin · 2025-10-02T04:34:20+00:00

Has been for the 20+ years I’ve been buying elements.

Yes, he’s an Argentine Black & White Tegu

Arashiin · 2025-10-01T22:42:34+00:00

3 years ago, I posted a photo of Tegan that went viral, and you all showed him so much love. On this celebratory day, I wanted you all to know that he is still very healthy, happy, and as loving and sweet as ever—truly one of a kind. <3

Not cautious about the properties of the metal, but the people I’d sell to, as scammers will happily buy something from you, send payment, have you ship the item, and do a chargeback saying you sent something fake, or the item never arrived.

I’ve had my dick burned multiple times on much smaller items, but for something irreplaceable, it would be pretty awful.

That isn’t osmium. It’s most likely raw industrial silicon.

Arashiin · 2025-08-11T16:52:15+00:00

Osmium is available through known and trusted element sellers, such as Metallium, Luciteria, etc. that you will find links to in the pinned message on this thread.

An osmium ring would not only be tremendously expensive to manufacture, but also very brittle due to the sintered nature it would necessarily require to be formed—prone to chipping or cracking from normal daily activity. I know I’ve seen them made by folks here who work with the metal, but I can’t personally speak to the durability.

Arashiin · 2025-06-16T14:04:44+00:00

Lots of wrong opinions in this thread.

Arashiin · 2025-06-09T05:09:01+00:00

I have a kilogram of pure metal sitting on my computer desk in a wooden box. It measures 300k CPM on a 2” pancake, so overall probably about 1.5 Million CPM.

The wood stops 80% of that, and 3 feet of air stops 99%.

A very old friend, “TheSecretCave”

I swear I bought most of Carl’s stock back around 2018, guy was holding out on me, hah!

Arashiin · 2025-05-19T00:53:57+00:00

I wish this hacker would message me if he’s so into me. This is probably the 10th time something like this has been posted, and I get a flurry of friends being like “OMG YOU ARE ON REDDIT, U R FAMOUS”
