John,

This is not sea water. I have used cooking salt and also sea salt in=20
different experiments.

I will come to a conclusion in a day or two.

Stirring also does not change the behavior.

IMHO, it is cooking salt that varies in layers and not sea salt as per=20
one chemist's opinion. Sea salt is homogenous when dissolved.

Cheers

Ravi
