Calcium phosphate and salt in my attys, no thanks.
You can try it. Anyone can try anything once so please take video of the taste testing!
I don't know the amount of heat it takes to make calcium phosphate to precipitate out, but it may make an interesting experiment. I vaguely remember that it stays suspended in milk due to something unique about milk. Can't remember what the reason is though.
I think the salt clinging to the coil would cool the whole thing down fairly quickly though, so best to get results quickly.
We had someone try vaping some salt in their juice once. I enjoyed reading that too. I recall it did not have the desired effect.
Seriously though, I would not recommend it.
