I did this once. I'm not sure if the outcome will always be the same, but this is what happened. I made a fire with 91% isopropyl rubbing alcohol, then threw a half-handful of sea salt on it. The flame turned a deep green color, but it did not seem to change the temperature at all. I heard that if you use table salt, the fire turns bright orange, but I have never witnessed it firsthand.
It sinks into the sea
It sinks unless it is sealed.
The salt doesn't evaporate, just the water. The salt stays there. That's how we get sea salt.
it goes brown
Well yes you can... but the sea water as you all know is FULL of salt. As such, the salt will make the soil unusable. All fire needs 3 things to exist: Heat, fuel & oxygen. Remove enough of any one of these & fire will cease to exist.
It becomes a black hat.
About 80% of the salt is initially not incorporated, and that 80% just drains back into the ocean.
It's not a bad idea as long as you don't drink too much of it.
Sea salt comes from the sea and tastes like sea water.
Sea salt is extracted from sea/ocean waters.
Of course, yes !
Sea salt is not flammable.
