Mini element collection. For some reason the set described in the previous sample contains two different samples of manganese, one in each box. Go figure. Source: Blake Ferris Contributor: Theodore Gray Acquired: 15 July, 2004 Price: $61/set Size: 1" Purity: >98% |

Mini element collection. This is a nice little set from the 1960's. The enclosed price list indicates it cost a few dollars, and the enclosed mercury sample indicates it predates current environmental concerns!

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 ampoule 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 gasses) 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.

Sample from the RGB Set. The Red Green and Blue company in England sells a very nice element collection in several versions. Max Whitby, the director of the company, very kindly donated a complete set to the periodic table table. To learn more about the set you can visit my page about element collecting for a general description or the company's website which includes many photographs and pricing details. 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. The picture on the left was taken by me. Here is the company's version (there is some variation between sets, so the pictures sometimes show different variations of the samples):  Source: Max Whitby of RGB Contributor: Max Whitby of RGB Acquired: 25 January, 2003 Price: Donated Size: 0.2" Purity: 99.9% |

Lots of lumps. This is about a pound of lumps similar to the one I got from David Franco (see above). Since I know Franco sends only the very purest of samples, and since these look identical to the one he sent, I feel reasonably confident in assigning them a similar purity. They were obviously created by the same basic process. Source: eBay seller snooj Contributor: Theodore Gray Acquired: 22 August, 2002 Price: $10 Size: 0.75" Purity: 99.9% |

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 |
