Hello: Thanks for mentioning that wet sand and hot lead are no fun!!!! I could not believe the use of wet sand - go to foundry and see if they use wet sand when they pour steel
HOWEVER: No, we are not hallucinating -- "no lead gasoline" is a real reaction to the number of children who are mentally retarded because of lead fumes. You DO NOT have to BOIL lead to have vapors! It is called vapor pressure. Ice has vapor pressure, not just liquid warter, Hell that's called humidity! So do solid and liquid lead. Eating lead is not nearly as toxic as the vapor, if you eat too much you'll barf. You have to remove lead paint from old home to sell them. I am not anymore happy with the Safety Police and OSHA then the next chemist - they ruined most of my fun experiments and research - but lead is really bad for little kids. You can check all of my gentle claims on any lead website, gov regulations, etc. regards, Jim On Mon, 23 Jan 2006 14:55:31, [EMAIL PROTECTED] wrote: > My God, are you guys hallucinating?
