A toxic gas is given off. What is that gas?
There once was a place called
Camelotimage

    Wouldn't gold have to reach its boilling point to give off any fumes?

    Worry is the interest you pay on a debt you may not owe.

    Could you be confusing this with the method old miners used to refine their gold ?

    They used Liquid Mercury to seperate out the gold from the crused ore.... Then they would heat the Liguid in a copper pan allowing the Mercury to vaporize... which is a poisonous gas..

    No, things give off some vapors below their boiling point - this is how water evaporates eventually at room temperature even though this is much below 100 C. At the boiling point, the vapor pressure is equal to atmospheric pressure, but there is some vapor pressure at lower temperatures. PURE gold wouldn't give off any 'toxic' fumes, so you would be talking of some impurity. Mercury seems to be a likely culprit, it is used in some purification methods, it is volatile, and is toxic.
