Potassium from K2CO3 + Mg lathings
On Youtube I found this video of some German guys making a kilo (!) of potassium metal.
https://youtu.be/FPjpXiZ1rSY
It looks amazing, although safety measures are not always observed.
I don't have these professionally made equipment, but I tried it with my humble stainless steel retort doing the same (but not a kilo !).
I heated 13g K2CO3 + 7g Mg lathings to about 1000 C in a propane furnace and after five minutes I captured 3.6g of potassium metal in an oil bath.
Even simpler than using KOH.

Fascinating! This does seem to be the easiest way to make potassium - I wonder if it would work with sodium.

You know, I think it would be easier to get potassium carbonate to an anhydrous state. Second it has been shown magnesium reduces carbon dioxide as
well as potassium oxide and more than likely sodium oxide. BTW, where IS the carbon soot? Is the carbon dioxide being reduced or off gassed by
displacement?

When I opened the retort after cooling, there was carbon powder in the upper section of the retort.
Before I heated the K2CO3 to remove any moisture, but it is far easier than from KOH.
