Tellurium is my favorite element name because I once defused a brewing trademark problem by convincing a guy that "Tellurium" would be a better name than "Wolfram" for his planned software.
Reports Tryggvi:
I find it funny that you should have talked someone into using "Tellurium" for a trademark. Much of the chemistry of tellurium was only investigated after WWII, when "glove boxes" became commonly available. (Developed for handling nasty nuclear stuff). Tellurium is fairly toxic, but even sub-hazardous exposure will produce a BO so bad that friends and acquaintances will endeavor in staying far upwind from the hapless researcher. It may take weeks or months for the scent to go away.

Tellurium Sample from the RGB Set
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):

Tellurium Sample from the Everest Set
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.

Tellurium Big crystals
3D3DBig crystals.
I was about to bid too much for some small tellurium crystals on eBay. Fortunately Max came to my rescue, saying he had plenty and it wasn't really very expensive. So now I have a nice big chunk and it didn't cost me anything.

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.

Tellurium Hollow cathode lamp
Hollow cathode lamp.
Lamps like this are available for a very wide range of elements: Click the Sample Group link below to get a list of all the elements I have lamps like this for. They are used as light sources for atomic absorption spectrometers, which detect the presence of elements by seeing whether a sample absorbs the very specific wavelengths of light associated with the electronic transitions of the given element. The lamp uses an electric arc to stimulate the element it contains to emit its characteristic wavelengths of light: The same electronic transitions are responsible for emission and absorption, so the wavelengths are the same.
In theory, each different lamp should produce a different color of light characteristic of its element. Unfortunately, the lamps all use neon as a carrier gas: You generally have to have such a carrier gas present to maintain the electric arc. Neon emits a number of very strong orange-red lines that overwhelm the color of the specific element. In a spectrometer this is no problem because you just use a prism or diffraction grating to separate the light into a spectrum, then block out the neon lines. But it does mean that they all look pretty much the same color to the naked eye.
I've listed the price of all the lamps as $20, but that's really just a rough average: I paid varying amounts at various eBay auctions for these lamps, which list for a lot more from an instrument supplier.
(Truth in photography: These lamps all look alike. I have just duplicated a photo of one of them to use for all of them, because they really do look exactly the same regardless of what element is inside. The ones listed are all ones I actually have in the collection.)

Description supplied by the source:
This is what happens when pure tellurium is melted homogeneously and allowed to solidify in a vacuum-fairly unbelievable crystals. Disks like the one shown, with the incredible crystalline structure, are only as difficult to make as the largest mold or vacuum arc chamber available to you.

Description supplied by the source:
This is what happens when pure tellurium is melted homogeneously and allowed to solidify in a vacuum-fairly unbelievable crystals. This piece was broken off of a different disc in order to get some insight into the internal structure-surprisingly, you can see that the top crystalline surface is basically analogous to frosting on a cake-it looks completely separate from the main melted body. Beautiful crystals though, like ice on a window.

Tellurium Bismuth telluride heat pump
3D3DBismuth telluride heat pump.
This is a small bismuth telluride thermoelectric heat pump. Apply a DC voltage and one side gets cold while the other side gets hot. If you attach a good heat sink and fan to the hot side, you can pump heat out of something, cooling it down. This particular device was deployed inside a USB-powered mini-fridge designed to cool one can of soda using power from your computer.

Tellurium BiTeEr lump
3D3DBiTeEr lump.
This is a roughly bullet-shaped lump of what is described on the envelope it came in as about half Bi, half Te, and a trace of Er. Actually the exact percentages are given, but in deference to whoever discarded this item I'm not listing them, in case they represent some kind of secret formula for making really good lumps of metal, or something. Ethan seems to have gotten into a batch of strange tellurium compounds someone at his university was throwing away: I'm going to be listing more of them soon.
Reader Anders Mikkelsen suggests that this alloy may have been used in research into Peltier junctions.

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.

Tellurium Insane mineral capsules
3D3DInsane 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.

Tellurium Himalayan sea salt
3D3DHimalayan 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.
