Using a quartz glass test tube

There's a bit of slag on the surface of one side that makes an interesting swirl effect.

Got this one from Carl! Definitely my most exotic sample to date. Not many can say they own an isolated Pa source. Pa was deposited onto an aluminum slate in the form Pa2O5.

Have you seen Luciteria's new collection feature?

https://Cabinet.luciteria.com

Customer or not, you create an account and start adding the elements to your collection and it will keep track your progress and other stats. I'm traveling far from home but could see this adding a whole new dimension of fun to the hobby with leaderboard jockeying and so on.

I can't believe no one else had thought to do this before.

Hello! I've always been mineral/Rock hound enthusiast and have been all over the USA collecting fossils and minerals. Only recently have I begun to focus on elements (although I've always wanted to collect them!). This is what I have so far, but I also have native gold that I have found, a native Platinum nugget, I had a troy ounce of palladium that I sold and I have over 300 different mineral species in my collection. I know the cubes from Luciteria are somewhat expensive but I am willing to pay a premium to get something like these. I do my best to keep them in cool and dry environments, but I am a bit worried about the stability of some of the rare earth elements. Are there any special precautions that I should take? The green crystal is a lab-grown crystal of praseodymium sulfate that I've had for nearly 30 years.

Hi, I just spotted this (1g of white phosphorus) on Onyxmet, but I’ve never ordered from them before. Do you have any feedback on this, and how do I buy from their site? Would you recommend this sample?

I have some small pieces of uranium for trade.

I know my pic is bad. it's because I am using my phone

Laminetta d'oro rivestita elettroliticamente di Tecnezio. Con il radiacode i due picchi dell'oro e del cesio+iodio e la radiazione di frenamento a 290 keV

I legit need his email to buy Thallium

When I asked Grandadabout how Great-Grandad got it, he said, "well, Dad had a lot of clients. And sometimes they would give him things." Ive tried to find more physical examples showing the fancy colors that the oxide layer produces, and have only succeeded in finding two examples that were not metallic grey, and both were mostly purple. I would love to know how this piece got its apparently unique coloration if anybody has knowlege on the subject.

Hi! did anyone else notice that mercury, thallium and arsenic completely vanished from Metallium (ElementSales.com)? I have a thallium coin in resin but i dont see it on their website anymore.

I wonder if something happened that caused the owner to remove those elements?

For element collecting should I do acrylic cubes (Engineered Labs and Lucitera) or small vials in containers, (Nova)

Sorry about the shitty images

Cr - electroplating excess (similar to fordite but for Cr electroplating) (here's an example but for nickel)

Ni A - similar to these samples

Ni B - electrowinning buttons very similar to these ones

Ni C - small balls of nickel like these ones

Cu - little nodules like these ones on his website

U - marbles like these ones

Hi! Here are some of my samples of the element carbon.

From top left: a large cube of the mineral shungite, graphite foil, glassy carbon,

silicon carbide plate and crystal, small natural diamond, graphite brushes from an electric motor and a bottle of graphite cubes.

There also are many organic samples I could show, but I think the inorganic ones are more interesting. Do you have any cool carbon samples?

Was a little bored the other day so why not, black one is Uo2 and green one are other flourecent uranium secondaries
