Heavy lump of master alloy. I think this is a lump (about 11 pounds) of manganese-steel master alloy. Etching with HCl (see next sample) produced an interesting dendritic structure, indicating that the material is not homogeneous. The source described it as pure manganese, but this is not likely.

Museum-grade sample. In early 2004 Max Whitby and I started selling individual element samples identical or similar to the samples we use in the museum displays we build. These are top-quality samples presented in attractive forms appropriate to the particular element. They are for sale from Max's website and also on eBay where you will find an ever-changing selection of samples (click the link to see the current listings). This flame-sealed, argon-purged ampule of manganese contains 50+ grams of electrolytic manganese plate, very beautiful lustrous stuff. I chose this sample to represent its element in my Photographic Periodic Table Poster. The sample photograph includes text exactly as it appears in the poster, which you are encouraged to buy a copy of.

Sample from the Everest Set. Up until the early 1990's a company in Russia sold a periodic table collection with element samples. At some point their American distributor sold off the remaining stock to a man who is now selling them on eBay. The samples (except gases) weigh about 0.25 grams each, and the whole set comes in a very nice wooden box with a printed periodic table in the lid. To learn more about the set you can visit my page about element collecting for a general description and information about how to buy one, or you can see photographs of all the samples from the set displayed on my website in a periodic table layout or with bigger pictures in numerical order.

I have two photographs of each sample from the set: One taken by me and one from the company. You can see photographs of all the samples displayed in a periodic table format: my pictures or their pictures. Or you can see both side-by-side with bigger pictures in numerical order.

Photo Card Deck of the Elements. In late 2006 I published a photo periodic table and it's been selling well enough to encourage me to make new products. This one is a particularly neat one: A complete card deck of the elements with one big five-inch (12.7cm) square card for every element. If you like this site and all the pictures on it, you'll love this card deck. And of course if you're wondering what pays for all the pictures and the internet bandwidth to let you look at them, the answer is people buying my posters and cards decks. Hint hint.

RbMnF3 crystal. I don't even know what you'd call this other than by its chemical name: It's a pretty pinkish little bar of what is probably a single crystal, crudely cut and roughly surfaced, but not polished to any significant degree. It came from a batch of old samples and research materials being discarded by Ethan's university. The fact that it's translucent and colored makes me think it might be intended as some kind of laser material, whether it worked or not I have no idea. The fact that they threw it away may or may not indicate something about its usefulness.

Manganese Nodule. Do you remember when manganese nodules were going to be the next great gold rush? When a great new natural resource was going to be unleashed just as soon as someone figured out how to dredge them up from the incredibly deep ocean? Did you ever wonder if there might not be some in shallower water? Well, guess what: The whole thing was a complete fabrication. The CIA wanted to recover a Soviet submarine that had gone down in very, very deep water in the Pacific, and they needed a cover story because they knew that there was no way they could build and deploy the highly specialized kind of ship required to recover something from such great depth without the Russians (who knew exactly where their submarine had gone down) figuring out that something was up. So they enlisted Howard Hughes, the richest man in the world at the time and a notable nutcase, to pretend that he thought these manganese nodules, which just happened to exist only at great depths, were the next big thing. He built a large, specialized deep sea recovery ship, the Glomar Explorer, and sent it to find, um, um, manganese nodules, that's right, we're looking for manganese nodules. They actually did find the Soviet submarine and were able to recover parts of it. Eventually people forgot about the manganese nodules. If you don't believe me, read this report on the subject: http://www.fas.org/irp/program/collect/jennifer.htm This particular nodule was recovered from 5100m of water in the central pacific by the MS Valdiva working for the Metallgesellschaft AG, Frankfurt am Main. I wonder if they thought they were going to get rich. Source: eBay seller mitryrock Contributor: Theodore Gray Acquired: 3 June, 2003 Price: $20.50 Size: 1" Composition: MnNiCuCo |
