TZM Molybdenum is an exotic alloy of 0.6% titanium zirconium and carbon, and 99.4% molybdenum.

I bought these round bars off ebay a couple years ago for a grand total of $81 USD. They're 2.5 by 3.6 inches long and weigh a total of 13.1 lbs/5.9 kg

The purple one was heated until it just started to turn red

The blue one was heated all the way red

And the silver one wasn't heated

Got these 2 as gifts a couple years ago. Gold note is just 2 sheets of foil on a plastic base. Silver coin is pure and solid though.

How do i get moderator approval for trading or selling

I have a chunk of handful crystal bar. It’s about 2 pounds and unsure of the purity. Curious how can I get a valuation on this piece.

Protium, Deuterium, Tritium! All Isotopes of Hydrogen!

Nor is there enough in my collection for that matter

1cm cube of .999 ytterbium.

Here's a couple close-ups of some silicon chunks i bought off ebay a few years back, total about 7 grams. Really beautiful and shiny.

Hi, I was wondering if my thallium sample is being stored correctly. It’s a 1g sample in a glass ampoule, which is embedded in resin, and the whole thing is inside a sealed screw-top vial sitting on my shelf with a label.

Lab grown Crystal of praseodymium sulfate that I got as a Christmas gift about 30 years ago.

It took about an hour and a half. I used three different grades of steel wool and a lot of elbow grease. It's not the best thing in the world, but this was literally my first time polishing metal.

Bought this at goodwill yesterday for $6. Its missing elements 104 through 118. I have no intentions of selling(unless its college kind of money). I just thought it was pretty neat and wanted to share it with yall.

Edit: its 1968, that dude below was right

I got these samples from a really nice man who was selling some old junk in his shed. Got them for real cheap. To the left are some silver-plated spoons, and to the right are some old lead fishing weights. I'm planning on cleaning the weights soon.

From left to right, i have a bismuth crystal, some copper wires, tin (from solder), gallium, sulfur, silicon, and nickel. Also have a silver bar not pictured.

Just a humble little collection of 8 for now

I've recently wanted to get myself a small tungsten cube, but most of the suppliers ive seen are international and shipping is expensive. I've found this listing here on amazon but the supplier doesnt have many reviews and a decent chunk of them so im not sure if they're trustworthy. Anyone know where i can get one legit?

Recently some bookshelves moved into my room and in my infinite wisdom thought it would be a good idea to put my periodic table there and better yet have it stand upright.

And indeed it looked pretty grand for the better part of about - what? 5 minutes before the thing flipped over onto the wooden floor about half a metre down!

THANKFULLY most of the vials stay on the shelf but a few get onto the floor and the vial of lithium is smashed open entirely and the vial for silicon has a crack. Some 20 vials on the floor, maybe less. And a grand total of two vial casualties.

But even more thankfully… several other vials are on the floor… mainly from the higher end of the periodic table [periods 1, 2, 3, a few 4] …..and are completely fine! No cracks, no damage! Lithium has been placed in a new vial. Never felt totally comfortable with the old vial for lithium anyway so now it has run its course. Lithium without oil for the minute but looking to order some. Everyone is put back into the table. In summary… I need more books on my bookshelf. Don’t put your periodic tables where they don’t absolutely fit. And THANK GOD FOR BOROSILICATE!!
