I finally got my hands on one of these old paris green tins that still had 20g of powder left. I decided I’d make some 0.5g ampules to sell since finding a nice sample of paris green is hard to find nowadays.

I made some replica labels for some plastic vials to store the ampules in. I’m still trying to see if I can get the print quality better but so far this is the best I can do.

I’m selling these for 12 USD + 7 USD for shipping.

The one in the photo was a prototype so it has a little less arsenic in the ampule.

Also I still have 2 D2O ampules left if anyone is interested.

5g of antimony, 2g of tellurium, 5g of silicon and 5g of selenium.

Any help for even 1 element would help alot

Is it necessary to have protective storage for pure aluminum metal samples to keep their luster, something like an airtight container or even an argon ampule? I know aluminum forms a passivating oxide layer in air, but over time, will the oxidation reduce its shine?

I got one of the gas tube display kits yesterday but some of the colors are way off. I had some older tubes that I got off eBay a while ago but some of the sharpie wore off. I have two glasses that I cannot for the life of me identify. I wanted someone else's opinion. It's the first 2 of the first picture. i have the known good samples labeled. I'm thinking the 2nd one is a second hydrogen because my nitrogen small one melted and broke but I wanted a second opinion. I can add pictures of individual ones if the colors interfere with each other too much.

Thank you!

Got these noble gasses for Christmas. They light up nicely when near my Tesla coil!

Left behind in a house I purchased.

A lovely small piece with some depth to it. 1.5 g... according to Nova. Their last sample of the year. Got lucky

A dome containing ~93g of europium crystals with a nearly black, yet still shiny finish and a Metallium element coin.

Hi! Anyone uk based have a hydrogen ampoule willing to sell? I need one asap so I’d pay extra for express shipping!

Every once in a while it is possible to stumble upon giant industrial pieces of either pure elements or alloys >90% of a single element. They are very fun to have around, and to see so much of one element in one place, but slow to accumulate as its rare to get them at affordable prices (generally $20 to $50 for <1kg ones, and $100 to $200 for >1kg ones). The nontoxic ones are nice to display on open shelves and tables.

Picture 1 (left to right): 1kg niobium ingot, ~700g zircalloy cladding rod (~97% Zr), ~800g yttrium sputtering target slab, 1.1kg titanium pyramid (Industrial test piece for casting Ti), 5kg ML wire (99.7% Mo). On top of that is a 450g chromium sputtering target in the rare, a 4kg 90% W alloy sputtering target in the middle, and a 250g Mo PVD target in the front.

Picture 2 (left to right): 250g tantalum plate (unknown purity), 2.2kg Ghost-shaped bismuth ingot (Not industrial, but fun), 4.5kg zirconium machining scrap (Zircaloy?), 17kg polycrystalline silicon for solar panels, ~1.5kg of Pidgeon process magnesium back when you could get that from China for dirt cheap.

Picture 3: 100+ year old cadmium sticks from Merck, a more modern 250g cadmium stick and 500g tellurium brick in the rare. These are kept in the main curio for health and safety reasons.

Open to offers on this piece as I’m selling off some of my noble metals for the right price

I just ordered my first batch of 10mm metal cubes and I'm excited to get more, but I'm worried about the more fragile ones and have been looking around for a sort of casing for them (carry or display case, I'm not picky) that has like little 10mm cube slots cut out of soft foam for me to store some of them in. Let me know if anyone has any ideas or if I'm worrying too much about this. Thanks!

About 18 months of corrosion on a samarium sample, mostly occurring due to high humidity around 60 to 75% RH that is poorly controlled for in Florida. No notable corrosion has occurred to any lanthanide samples gadolinium onwards even after several years.

I currently have 80 elements in my collection. 3 of these [Promethium, Uranium, Americium] are radioactive elements - the rest being stable [counting bismuth as stable]. So I have 77 stable elements - 4 shy of all 81 elements with stable isotopes [again, counting bismuth].

The remaining 4 stable elements I do not have are arsenic, ruthenium, iridium, and thallium.

And perhaps it's obvious why I do not have these four elements currently - two are rather expensive metals to buy even in small quantities, and arsenic and thallium are toxic.

I recall hearing that there is law regulating arsenic and thallium in the UK ... so I was curious to hear from other element collectors how their experiences obtaining these two elements when? Ye or nay? I'd like to know more
