My peeve is that I regularly donate, and still get the reminders. Even after I click the box that says I already donated, I get nagged 6 hours later.
If you are interested in a well-written and interesting account of the history of industrial fertiliser, I suggest this:
It’s an objectively better word than “potassium.” Oh well. We also have four elements named after the same stupid town. Chemists suck at naming things.
Ytterby must have a good publicist.
Or a lot of great, albeit unimaginative, chemists.
That was my underlying conceptual framework.
In practice, Trump will issue waivers for vital products, like he did last time. Which is why a trade war is attractive to him: he gets to award public friends, punish public enemies, and encourage the powerful to keep their heads down. Trump does what he does very openly.
Efficient economies organize production according to minimizing costs, not sucking up to whoever is in power in the moment. This sort of thing can do real damage to economic prospects, albeit under a fair amount of statistical noise.
Assuming his term of office ends in about 4 years via whatever mechanism, it’s a good bet much of the damage will not be fully manifested for another 5-10 years after then, but it will easily take 50 years after that to repair.
It may also refer to potassium carbonate or bicarbonate?
Which were the original sources, extracted from wood ash long ago, as you say.
Don’t know if there is an ‘official’ definition?
Wikipedia lists a variety of potassium compounds as “potash”, depending on their composition. Other than the common names giving a hint to their usage (such as potassium hydroxide being “potash lye”), they’re apparently all “potash” and you know which compound you need according to usage.
Technically correct, although one might quibble that the common use of the word “potassium” in the N-P-K trilogy is not altogether wrong as it’s the potassium ion of the KCl salt that makes it an important component of fertilizer. It’s similar to how the health industry refers to table salt as “sodium” when they tell you not to eat too much of it – they don’t mean the silvery metal, which is so highly reactive that it’s downright dangerous. But they do mean the sodium ions from NaCl which are essential to life and support the function of cells, nerves, and muscles.
Speaking of table salt, one could say that potash also has dietary and medical applications, wherein it does business under the name “potassium chloride”. KCl has a salty taste and is used as a salt substitute in sodium-restricted diets, and also for the treatment of potassium deficiency (hypokalemia). Of course we’re talking about the pure salt here, whereas I imagine mined potash is pretty rough stuff in terms of impurities.
I happen to like tungsten (Swedish for “heavy stone”; tungsten is uncommonly dense).
“Wolfram” was cool too though.
I have a client that makes things out of lead and tungsten. Man, you don’t know how dense until you try to pick it up.
I have a pattern coin made out of tungsten; it IS heavy. Looking up its density, tungsten is 19.3 g per cubic cm, while gold is 19.32 and silver is 10.49. Plus it’s really dark and hard to make an impression on.
Of course, it’s contraindicated for people with heart conditions, as it can be dangerous to them… that being, of course, the primary reason why one would be on a reduced sodium diet to begin with.
Potassium is pretty reactive too.
Not for heart conditions as a general class. For some with congestive heart failure. And with the use of some specific medications.
Other heart conditions I do not think have any specific potassium restrictions and increased potassium with lowered NaCl intake, especially relative to the standard American diet, is a typical recommendation for hypertension. Which is often comorbid with many forms of heart disease. Lowers stroke risk. Best to get the increased potassium in vegetables and fruits of course!
About its use as a salt substitute to help with hypertension:

Hear, hear! Potassium compounds are often significant because of the potassium in them. There are a few elements that are like this. In speech, the name of the important element and the name of the compound may be somewhat interchangeable, and little understanding is lost.
This can be pretty amazing. I had a part made once of tungsten, a half inch thick plate about 6 by 3 inches. When it’s laying there on the table, and you go to pick it up, you might interpret it as being glued or bolted down. You kind of have to pry hard to get it to stand up 3 inches tall, and then change your grip to get it up.
You can buy tungsten cubes on Amazon, suitable for display. Available in various sizes, from 1" for about a hundred bucks up to 3" for a couple thousand bucks. The 1" cube weighs about 10 ounces, and the 3" cube weighs about 17 pounds.
Helluva paperweight.
Wow, that’s a fun cite.
I like the 1.5" cube weighing a kilogram for $200. I especially like the mixed units. Might need to have one of those.
The other fun item was that your search for “tungsten cube” that brings up an aluminum sphere sold by Midwest Tungsten Service. “For all your tungsten repair needs”. 
So much confusion in a small package.
Potash was a word I encountered sometimes while reading as a kid but didn’t hear pronounced for many years. Therefore, I had it wrong in my head for a long time and I still catch myself on the long O: poe’-tash
