Golden eagle, I do not think it makes much difference if you are over or under with the salt. I have read that you should be able to float a potato if the salt is at the right proportion. I have not tried it myself. I'm sure you know that the salt is more severe than still water alone and works by helping to eliminate the air bubbles that tend to surround the hot iron being quenched.
