Can someone explain the differences, if any, between using potassium citrate
as opposed to just sodium cloride or sodium citrate in the salt printing
process? Why does Barnier swear by potassium citrate? Is it newer and better
i.e. was potassium citrate simply just not around in the 1840s? Thx.

p.s. what about ammonium chloride? A salt, is a salt, is a salt? No!?
