If there was enough heat in your room, then yes it could have had some vapor release. ONe story I heard about a guy that used to PLAY with liquid mercury. He was fasinated by it. oneday a bit of it dropped onto a hot plate and he died weeks later from acute mercury toxicity. that is how dangerous the vapor can be concentrated like that.

Yours would not be like that, but it is possible some of it may have escaped as some vapor. Have you removed amalgams? and have you or are you chelating? if not, I recommend you do to lessen your exposure as much as possible. Plus do not eat any seafood! I'm sure you know all this, but when a person has been overexposed, even by other sources, they often find their amalgams suddenly become a big problem, wheras before they may have been coping better.
