KOH and it is indeed available as a crystal. To the point where the dealer in Providence insists that potassium carbonate doesn't exist.
I don't think it s critical to have. Dudley was always peculiar in wanting it but you can overwhelm the carbonate with stannous oxide without breaking a sweat. I don't stock it and he keeps trying to sell me his. Any of the potassium compounds are going to be hydrophilic so you have to get them away from humidity. Either use zip locs or air condition the storage shed.
