That mud is most likely a mixture of iron hydroxide and nickel hydroxide. Potassium carbonate is highly soluble in water. It won't be precipitating out.

I think its Iron carbonate edisons regeneration of cells used the steel case with pos & neg shorted to regenerate pushing carbon out of the Iron carbonate
which would be in contact with the case.
The other case you can get made is a steel one plain steel mig welded a lip around the top inside to support the white cell top.

Yes, the iron and nickel hydroxides will turn to carbonates after they have been exposed to air for long enough, same as the potassium hydroxide.
