Topaz. Is it better than our 17th President?

I don't know much about the presidency of Andrew Johnson. Widely regarded as one of the worst presidents in the history of the United States, his political career is tarnished by his being the first president to ever be impeached. With such a weighty political history, it may surprise you to find that I am the first person to ever compare this ill-regarded politician with a pyramidal silicate mineral containing aluminum and fluorine. And yet, here we are.

So with that in mind, let's look at the players involved here. In one corner we have Andrew Johnson...

And in the other corner is our decidedly less humanoid character, the mineral topaz...

You can't really tell from that photo, but that's a picture of topaz. Also of some sore throat spray. I have a cold.

So obviously there are a few physical differences between the two parties, the least of which being the complete lack of a nervous, digestive, circulatory and all other systems in one of the subjects. For ease, let's make a list of the physical highlights at play here.

ROUND ONE - Physical AppearanceAs you can see, the similarities are few and far between with regards to the physical appearance of topaz and our 17th president. The biggest discrepancy would have to be in the area of hardness. A topaz crystal comes in at 8, making it the hardest mineral we have looked at so far. The hardness scale breaks down a little once you get past 6, and basically it tells us that the only thing that can scratch something with a hardness of 8 is something with a hardness of 9, which isn't terribly useful. Ah well. You think you're so smart, you come up with your own list. One area where this DOES come in handy is when you are trying to figure out if you have found topaz or quartz, which tends to look a lot like topaz. Look at this madness and see if you can guess which is which!

It's the ultimate challenge! Has it driven you mad with confusion yet? Do you feel the walls of your reality breaking down???? Well, I'm not going to give you any hints. I'm not here to be helpful. Well, alright, maybe just one little hint.

There. Hope that helps. So the main point to remember is that because quartz has a hardness of 7, you can scratch it with topaz, but you can't go the other way. It's like some sort of cut-rate time machine. Except typically time machines emit sparks and whistles which make them way more interesting than either topaz or quartz. What are we talking about again?

Moving along, unlike humans, topaz sticks to a few basic shapes. The most common shapes (in Utah anyway) are crystals that look like little crayon tips. Something like this....

Alternatively, President Johnson looks like this (regardless of location)

Except a little grumpier. I couldn't quite capture the anger. Ah well. Like all of us, President Johnson was encased in a fleshy human body. Geologically speaking, the human body is an unfortunate invention. Soft, pudgy, occasionally reeking of onion, our fleshy suits don't even have the strength to outdo the weakest of minerals. But don't fear, my fellow fleshy pods of weakness! Let's look at this comparison from a slightly different angle...

As you can see, our human counterpart starts to catch up a little when we look at what both contestants have achieved in their lives. Topaz has never lead America, but to be fair topaz has never been deemed so inept that it was impeached twice. So maybe things are still tilted in topaz's favor. So, we can see that the word "topaz" comes from the name Topazion, which may or may not have been a real island located in the red sea. My research has lead me to believe that this may or may not have been the island in question....

You can't tell, but that's an island in the Red Sea that has since been re-named a much more tame "St. John's Island". It is from this little island that the first gemstone to be named "topaz" was mined. But it wasn't the topaz that you and I are interested in. The term topaz first referred to this little guy....

That is a mineral named chrysolite, and it also looks a lot like topaz. Lots of things look like topaz. Anyway, later the term "topaz" was given to any mineral that was slightly yellow and gem-like, much like how the term "taco" refers to 800 different types of food at Taco Bell. Then at some point it was assigned to the mineral we all know and love.

President Andrew Johnson, however, has always been know by the name "Andrew Johnson", as that was the name he was given at birth. I don't feel like I have to explain this process.

So what is it exactly that makes topaz so great? Why should we care about it? Why are we reading this? Well, the answer has to do with that great shiny quality that it possesses. Humans love adorning themselves with shiny things. Topaz even shows up in the bible, which is basically a way of saying that it is the preferred gem of the Heavens. Andrew Johnson is far less recognized by biblical scholars. Anyway, in addition to reflecting light well, it is a very hard mineral. So unless you are frequently forced into situations where you are rubbing against diamonds (which is weird), the topaz is unlikely to get scratched. This is good news for topaz as its use as a gemstone is all it is really good for.


You can zap topaz with radiation to make all sorts of crazy stuff happen! Well, mostly it just turns blue.



You can zap Andrew Johnson with radiation to make all sorts of crazy stuff happen! Well, mostly it just turns blue. And dies.


Chemically, our two contestants are again fairly different...

Topaz clocks in with 56.6 percent Al2O3, 33.4 percent SiO2 and 10 percent good old fashioned H2O. Also sometimes fluorine shows up and the OH molecule asks it to hold its place while it uses the bathroom. But then the OH molecule just decides to take off so the fluorine is slowly accepted into the community on a permanent basis. Until it falls behind on its HOA payments anyway. HAHAHAHAHAHA!!! Ahhhh, adult situations.

So we know why topaz is important, we know what it is made from, and we know that it is indeed likely better than our 17th president. But HOW does topaz form?

Does it form from smoking too many fake cigarettes?

How about fake cigarettes and some really stale candy?

And for some reason here it is with an old bottle and the first season of Psych

Sadly, no, topaz doesn't form from any of those things. It forms when a huge blob of magma cools and releases a bunch of hilarious gasses. Near the end of the cooling, the gasses are rich with our good friend fluorine, which meets up with silica and aluminum rich waters that are flowing around. The two meets, they get to talking, they date for 3 to 6 months, they get married, and then secretly resent each other for the rest of eternity.

Say you are the type of person who insists on "actual knowledge". Well, here's something for you. The actual chemical formula that explains why topaz shows up sometimes.

8KAlSi3O8 + 2F2 + 2H2O becomes 4[Al2 (F, OH)2 SiO4 (Topaz) +20 SiO2 (Quartz)+4K2O + O2

I don't know about you, but I think "actual knowledge" is boring. Let's just say that topaz forms due to dark elf magic. Also Andrew Johnson. He also formed due to dark elf magic.

And so ends topaz. If you want a piece of it and you live in the western U.S., you can always visit Topaz Mountain. It will take you 20 seconds to find a piece of it and another 20 seconds to get bored with it.

Finding Andrew Johnson may take longer.
