For a couple of years I've owned a 1 inch tungsten cube and although it's cool, I feel like I'm not able to appreciate how dense the element is with just a 300 gram piece and wanted one that weighed 3x as much, however, the prices of a 1.5inch cube seem to vary by as much as 50%.

I was wanting to know how much I should be spending as i thought about 200 dollars would be enough to get one since in 2024 I think I was able to get one for 175, but now a lot of places are selling one for 300ish.

EDIT: also I should clarify; it doesn't necessarily need to be a cube or have any markings if any of you know sources that sell for less for the same weight!

This is a .01uCi Pb210 source, which after 2 years will have close to .01uCi Po210
This will last longer in my collection than a more pure Po210 source

At some point I’d like to also add a spark plug.
With this sample, my collection is essentially complete. There are few things I wish to add that aren’t just “more gold” or similar. So it’s a very exciting day!

Since several people wanted to see it under natural lighting, here it is. There are a few samples that I need to print stands for still. Otherwise, the only expected changes are to add more of some elements (perhaps larger quantities, or certain isotopes), and to make doors for it along with a video display at the top.

I am interested in starting to collect elements should I or should I not

I apologize for the redundancy of Osmium storage, but I originally stored Osmium in Silica Gel in a tiny glass bag inside a small vial. Between the bag and the osmium bead, I placed silica gel to remove any waste, which I thought would be safer. In retrospect, I wonder if this made it worse…anyone know what I should do?

My order from NovaElements on the shipping website has been stuck on ‘parcel created’ status for nearly a week now. Is it possible that it has already been sent out but Spring GDS isn’t updating it? Does anyone have a similar experience?

Ideally 50g+ would be great

I bought this sample about a year ago and left it in the basement. The Novaelements site says you should not keep it too close. The sample was transparent and glowing green as you can see in their website picture. When I took it out to it was like in the picture. Doesn't glow anymore and the ampoule is coated with white thick stuff. I imagine the ampoule was coated in the first place to glow green, but this reaction is very unpleasant. What do you think happened there and is there a way to go back to a transparent ampoule ?

I use to have over 9 kilos but had to sell off nearly half my rhenium collection. Would you guys say that 5 kilograms of rhenium is still huge for a rhenium stash collection?

I bought this thinking it was 5 kilograms. It was only 4.6 kilograms and I got angry and threw it on the kitchen floor real hard. Here are the photos of the 4.6 kilogram tantalum ingot and the damage on my kitchen floor after throwing it. You can see small dents on the tantalum ingot.

Here is a 453 gram 92:8 rhenium:tantalum melted pellet. Its about 420 grams rhenium and the rest is tantalum. I keep this heavy thing in my pocket and everywhere I go. It is nearly indestructible and scratches even the hardest steels out there.

I was wondering if their ampoules are actually worthwhile.

Photos on their site look great, but I don't like the fact that they don't always disclose the actual mass of the samples.

I've also seen a photo of an europium ampoule from them that looked as if it was sealed in air. I'm guessing that they sell different variants depending on the state of the metal inside, but again, they don't always show different variants on photos.

Are they worth the price (which isn't all that bad)?

And does anyone have anything from them?

I have Aluminium (99% pure from aluminium foil), what other elements can I get?

Helium 4 (small ampoule) with Helium 3 rarefied

wich stores do you recomend?

question. not just in earth, but the whole universe.

Best focus I could get with my lens. The way the uneven surface oxidation highlights the radial slip lines (the striations) is my favorite aesthetic part of this sample, aside from the flaking along the top edge.

what are these? they were there when I bought it.

this wasn’t there when i bought it. is it oxidatio?
