So you support Gordon's original claim that there is no harmful
vaporization below the boiling point?


As I said before, please try to follow these discussions more closely so you
won't have to ask silly questions like that.

Without taking a position one way or the other on the merits, I simply
pointed out the logical fallacies in Grandma R's reasoning.


So you ignore the faulty information, which is a serious safety issue,
and criticize someone because they did not frame their story to your
satisfaction. Hmmmm.

The truth is that lead will vaporize at temperatures far below the
boiling point. Using minimal heat (i.e. staying close to the melting
point) is usually safe, but heating to higher temperatures, which is
possible with home equipment, can be hazardous. In other words,
soldering with a 40 Watt iron is safe; firing up the portable blast
furnace indoors to cast large leads is not.
