Bismuth is a major constituent of Pepto-Bismol, but other than that it's not widely known. It is starting to be used quite widely as a replacement for lead in hunting ammunition, because of the concern about the toxic effects of lead in the environment (after it stops whizzing through the air at high speed it settles into the food chain).

Bismuth has the distinction of being the heaviest stable nucleus: All elements past 83 have no stable isotopes. It is by definition a heavy metal (it's a metal and it's heavy), but unlike almost all other heavy metals, it's entirely non-toxic. That is quite odd and there's no doubt a story behind this fact.

Actually, when I say bismuth is the heaviest stable element, that's not entirely accurate: It's not stable. It was recently measured to be radioactive, but with the longest half life measured to date: twenty billion billion years. Which is to say, for all practical intents and purposes it is stable. But not quite. But then neither are quite a few other elements commonly thought of as stable. For all we know, all elements are ultimately unstable. Oh, and don't forget the sun is going to explode eventually too.

Bismuth Reagent-grade metal
3DReagent-grade metal.
Around 2001 Stephen Wolfram asked Ed Pegg and me if we could experiment with growing hopper crystals with bismuth. Ed bought some from Alfa Aesar and I brought in my small electric kiln to the office. We were able to create crystals almost immediately: Simply pouring into a stainless steel measuring cup, allowing to cool until the outer edge is solid, then pouring the center off is all it takes. We made several nice small hopper crystals, and it's obvious that one could make any number just by refining the conditions and using more bismuth.
See the fourth sample for a picture of one dish of crystals I made, along with a video showing how the liquid metal is poured off from the crystals.

Bismuth Home-grown crystals
VideoStoryHome-grown crystals.
This small dish of crystals was made from the reagent-grade metal that is the first sample under bismuth. Ed Pegg and I had made several nicer ones long before, but I wanted to make a video showing how you let the metal partially harden, then pour off the still-molten center to reveal the crystals forming from the bottom and outside.
For some reason, this time the metal behaved quite differently. It may have become contaminated with enough of an impurity (lead?) to change its characteristics, or the difference may have had to do with the fact that I was using a plumber's propane torch to heat it, rather than an electric kiln as before.
(I wasn't exactly being careful to control the conditions, as making this video was another one of the things I had to do between bouts of child care.)
In any case, the biggest difference was that this time, it did not form the pretty colored oxide layers. Instead the metal stayed absolutely bright, forming only a dull gray oxide film that was easily skimmed off before it started cooling.
The other difference was that the crystals were smaller, though they were still obviously bismuth-shaped square hopper crystals. This is almost certainly due to less-clean cups and more contamination in the form of particles that initiate crystals from many places at once.
Still, I got a decent dish of crystals, and a decent video of it. Click the story book icon for more details on the procedure for making the crystals.

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):

Max Whitby and I talked about publishing a wooden book/CD/DVD/mini element collection, but it didn't go anywhere. It would have consisted of a nicely engraved wooden "book" with a CD and DVD version of the website (for those with slower internet connections), and a set of nine safe, interesting elements in the form of cylinders, cast blocks, nodules, and the like. Think of it sort of like a mineral collection, except it's an element collection and it comes in a much nicer box. Here are a couple of pictures of the prototype:

Bismuth Safe shotgun shot
"Safe" shotgun shot.
These are pellets from a seven pound bottle of shot sold for "reloading", which is the process of making your own ammunition by combining cartridge cases (new or refurbished), primer, propellant and shot. Lead shot and bullets have been banned in many areas because they poison the environment. The main substitute materials are steel, bismuth and tungsten. Bismuth is very similar to lead in density, melting point, hardness, etc, so it makes a pretty direct replacement, unlike tungsten which is much denser, much harder, and completely impossible to melt under any kind of reasonable conditions.

Unlike lead, bismuth is highly crystalline and brittle: This means that solid bullets made of bismuth shatter into dust on impact with hard surfaces, which in turn means that bismuth ammunition is sold as safer for use in urban environments or other places where ricochet would be bad. Safe being a relative term in connection with bullets.

It forms hopper crystal like pure bismuth (see earlier samples), but much smaller ones. Interestingly, you can clearly see flashes of light across large areas of some of these pucks, which indicate that crystal formation was coordinated over a much longer distance than the size of the individual squares. I'm not sure what this means.

Link in multi-metal chain.
I had been wondering about how hard it would be to make a multi-part graphite mold with which I could cast chain links around each other. That is, given an existing link, cast a new one interlinked with it. This turns out to be quite do-able: Here is the mold I made (using my drill press as a vertical mill and a round-ended router bit):

In case you ever want to try this, I'll give you an important hint: The third link is the real test, not the second one.

Bismuth Strange crystal
3DStrange crystal.
The seller swears on a stack of bibles that this is natural (native) bismuth dug out of the ground in this form from the old Trajos silver mine in Chihuahua, Mexico. Unfortunately, this is not the case. The bluish cast does look very much like the film that forms on high-purity bismuth when it is molten, which may explain the seller's honestly mistaken identification. But this crystal is actually silicon carbide, possibly formed in an iron cupola from a reaction between the coke used to melt the iron and the silica fire brick lining the cupola. Because of the insistence of the seller that it was bismuth I made an effort to be be absolutely sure about the identification, which was achieved by an SEM-EDS (Scanning Electron Microscope coupled to an Energy Dispersive X-ray Spectrometer) at the Center for Microanalysis of Materials, University of Illinois (partially supported by the U.S. Department of Energy under grant DEFG02-91-ER45439). The instrument allows one to measure the elemental composition of individual microscopic areas of a sample, in this case the cross section of a single dendrite broken off the crystal. It showed a ratio of silicon and carbon consistent with silicon carbide on the inside of the dendrite, with a small component of oxygen found on the surface (and no doubt responsible for the bluish film).
Although this very sophisticated instrument allowed a definitive determination of what the crystal actually is, verifying that it is not bismuth requires no special tools: It doesn't melt. Native bismuth in this form would have been quite remarkable, as no such material is known to exist. But the fact that it's not bismuth in no way detracts from the fact that it's very attractive! It is one of the more beautiful crystals in my collection, and I really could care less where it's from.

Bismuth Etched bismuth heart
3D3DEtched bismuth heart.
As you can see from several of the other samples on this site, bismuth makes lovely square hopper crystals. What you may not realize is that pretty much any plain chunk of bismuth is full of these crystals, whether you see them or not. The spectacular display crystals are made by allowing a pot of bismuth to partially harden, then removing the crystal before the liquid metal around it has a chance to solidify. But the crystal is still there even if you let the pot harden all the way, you just can't see it because it's completely surrounded by more solid bismuth.

The surface of a cooled lump of bismuth (and most other metals) is formed by the interrupted faces of different crystal zones, oriented in different directions relative to the surface. Normally the surface looks uniform, because the orientation of the underlying crystal zone doesn't have any effect on how light is reflected, probably because right at the very surface the atoms are disordered by their interaction with air at the moment of cooling.

However, if you use acid to etch away the outer layers of metal, you can expose the crystal zones in a way which makes them reflect light differently from different angles. The result is that you see a patchwork of zones that sparkle alternately depending on the angle of light. These flat zones in fact go way down into the solid, you're just seeing the ends of them.

The size of the zones depends on the purity of the metal (higher purity gives larger zones, and making big display crystals requires very high purity bismuth, at least 99.99%), and on the rate of cooling (slower cooling gives larger crystals a chance to form). Look at the rotation video for this sample and you'll see the crystal zones sparkling in a most lovely way.

Ethan has this to say about the process of etching he used:
I discovered that the best way to reveal the crystal interior after I cast the heart was an acid process, three seconds in industrial hydrofluoric acid and then seven in concentrated nitric. Unfortunately, in my zeal of preparing the baths and baking soda rinse, I spilled a drop or two of the hydrofluoric acid on my arm, and promptly washed it off for 15 seconds. I then proceeded to boy scouts for an hour or so, came back and started dinner. By that point the dime-sized patch on my arm was bright red and beginning to hurt like a jellyfish sting, so I told my parents what happened. Half an hour and one poison control call later, I was lying in a hospital bed with a big compress of 2% calcium gluconate around my arm, and a lot of shocked nurses, unfortunately at about midnight on a school night. Everything turned out fine, my arm stopped hurting, my heart didn't stop, I didn't acquire hypocalcemia, and the bismuth turned out beautifully!
From this we learn two things. First, that hydrofluoric acid is not to be trifled with (and neither is elemental fluorine for that matter). Second, that Ethan cooks.

Bismuth Student's report on crystal making
Student's report on crystal making. (External Sample)
Jon Smith is a high school student who decided to write a science report on the factors influencing crystal formation in cooling bismuth. I think he did a really nice job: See for yourself. I particularly like the picture: Good thing bismuth isn't toxic considering this is obviously the family kitchen, complete with bread in the background.
The state of math and science education in this country is absolutely abysmal. At my kid's primary school they actually call the math curriculum "BS Math", which is an accurate description except for the fact that there is no actual math in the curriculum. (For some reason they always refer to it as BSM or Beginning School Math, but BS Math is by far the most appropriate form of the name.) There are many causes for the current horrible state of affairs, but I'm not going to get into that because seeing a nice student report like this gives one hope that maybe all is not lost.
This is what students all over should be doing: Something real. Doesn't have to be melting metal in the kitchen, just something real. I think it's great that there is at least one kid left in the country who isn't watching television instead of living.
