Was thinking more test tube / Bunsen burner type of set up but yeah I get what your saying I'm cynical that it will work myself can't see how a atomiser can provide enough heat to melt salt and as a mineral I highly doubt it could be vapourised atall but am interested in how it could work I'm sure there must be a way to make salt tasting flavouring but I doubt this is the way to do it was just a suggestion to see if any salt ( if at all ) will vapourise off as steam
It has to, vaporizers aren't really boiling the liquid completely, some liquid is boiled but carries small particles of liquid up into the vapor as well. Think of a pot of water, just before it boils it begins to give off white vapor, that's water vapor but it's not steam. Steam is invisible on a fully boiling pot the vapor only becomes visible when it travels far enough away from the heat to begin condensing back into liquid form. Vaporization and evaporation are really two different things, although closely related. This is how wet things dry out without reaching the high temperature it takes to boil water.
If it was straight evaporation (which would be impossible in such a small device) you would get the components of e-liquid coming off in the order of their boiling points. Ethanol, Water, PG, then VG (which has a boiling point 190C above water)
