Depending on the material of the vessel, the water will quickly, or over a longer period, eat away at the material. Depending on it's makeup, it will become a solution in the water changing the boiling point, and the water will either cease to boil because of a higher boiling point, or not return to liquid because of a lowered boiling point.
This assumes that the heat source is enough to boil the water and let it cool enough to return to a liquid, and not remain as superheated steam.
In which case, it will eat away at the vessel even faster.
