Like its neighbor mercury, thallium is toxic. In fact, it's quite a bit more acutely toxic than mercury, and it's even been used both as a rat poison and a murder weapon. (Arsenic is no good because the symptoms are too well known. The world's first (and perhaps only) thallium murder was a great mystery because no one recognized the symptoms for a very long time.)

0.1mm foil wrapped into small cylinder, 99.99%
This small sample was kindly donated by George (not 007) Lazenby, who saw the slashdot discussion. It came in a lovely little plastic vial taped shut with a warning attached not to open it, and a MSDS on Thallium. We haven't opened it.
George got this and the other samples he donated at a surplus auction of his highschool. It seems he was the only one there who appreciated the erbium foil. This sample and the others he sent had been donated to the school by a former student who worked at NIST (National Institute for Standards and Testing), where they had been used as x-ray calibration standards. This means they are probably very pure.

One gram lump
This whole business of selling strange, rather toxic or otherwise dangerous elements on eBay strikes me as quite peculiar. But it sure is fun.

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):

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.

  Thallium perfume.
Thallium is poisonous, putting in perfume would be a bad idea. Presumably this perfume was invented after the success of the perfume named simply "Poison". I guess they figured they would be a bit more subtle. Presumably, also, it does not contain any thallium.

Insane mineral capsules.
These minerals capsules are called "Immune Boost 77", from Morningstar Minerals. They are either being incredibly honest, or they really don't understand what they're saying when they list what amounts to nearly the entire periodic table on the label, as the "trace minerals" they contain.
Here is the list in all its glory, typed in by my daughter in exchange for my paying for a membership in the Miley Cyrus fan club: Antimony, Barium, Beryllium, Bismuth, Boron, Bromine, Calcium, Carbon, Cerium, Cesium, Chloride, Chromium, Cobalt, Copper, Dysprosium, Erbium, Europium, Florine, Gadolinium, Gallium, Germanium, Gold, Hafnium, Holmium, Indium, Iodine, Iridium, Iron, Lanthanum, Lithium, Lutetium, Magnesium, Manganese, Molybdenum, Neodymium, Niacin, Nickel, Niobium, Osmium, Palladium, Phosphorus, Platinum, Potassium, Praseodymium, Rhenium, Rhodium, Rubidium, Ruthenium, Samarium, Scandium, Selenium, Silicon, Silver, Sodium, Strontium, Sulfur, Tantalum, Thallium, Thorium, Tellurium, Terbium, Thulium, Tin, Titanium, Tungsten, Vanadium, Ytterbium, Yttrium, Zinc, Zirconium.
Some of them are just silly, like thulium, which has absolutely no biological function. Others are a bit scarier, like thallium and thorium that are deadly poisons, and tellurium, which makes you smell of rotten onions for weeks.
Basically what they've done is list everything that occurs in even trace amounts in mixed monazite sand, which is kind of what the stuff inside looks like. The only reason they aren't seriously harmful (I assume) is that most of these are not actually present in any meaningful quantity.
My attention is drawn to these and other similar mineral supplements every time I decide to see if anything interesting has popped up on eBay for one or another of the obscure rare earths. Generally speaking if you search eBay for those guys you get very little of interest unless you turn on the option to search the text of the item description as well as the titles. Then you get lots of trace mineral supplements that one can only hope don't actually contain them.

Himalayan sea salt.
There is a list of 84 elements that seems to pop up repeatedly in the ingredient lists of "natural" mineral products, supplements, pills, and the like. Even, it turns out, in salt. Here then is the list of minerals claimed to be found in all-natural organic Himalayan sea salt:hydrogen, lithium, beryllium, boron, carbon, nitrogen, oxygen, fluoride, sodium, magnesium, aluminum, silicon, phosphorus, sulfur, chloride, calcium, scandium, titanium, vanadium, chromium, manganese, iron, cobalt, nickel, copper, zinc, gallium, germanium, arsenic, selenium, bromine, rubidium, strontium, yttrium, zirconium, niobium, molybdenum, ruthenium, rhodium palladium, silver, cadmium, indium, tin, antimony, tellurium, iodine, cesium, barium, lanthanum, cerium, praseodymium, samarium, europium, gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium, lutetium, hafnium, tantalum, tungsten, rhenium, osmium, iridium, platinum, gold, mercury, thallium, lead, bismuth, polonium, astatine, francium, radium, actinium, thorium, protactinium, uranium, neptunium and plutonium. I wish someone would tell these people that, for example, neptunium and plutonium do not occur in nature at all, let alone in salt. Unless, I suppose, if you count nuclear fallout as a "natural" source of ingredients.
What bothers me most is what this says about the level of scientific literacy, both of the people selling the stuff, and the people buying it. Does no one actually read the list? Or do they read it an not realize how preposterous it is? It's enough to make you despair for the future of mankind.
Pretty salt, though.
