Subject: Re: [STMFC] Re:lead shot

Let's go easy on all this lead business. It

is TOXIC. Eats your

brain. Sure you can wash your hands after

you've been working with

it, but that's not sufficient. It's absorbed

through the skin, it

emits vapors from being handled, and if you

melt it, as some have

suggested for lost-plaster casting, it's

vapors are

absorbed directly

through your lungs. Lead dust from filing and

cutting it gets into

your body via lungs, mouth, and skin. And it

doesn't go away.

Once it, it ain't coming out.

This is mostly hogwash. Lead's vapor

pressure, even in

the liquid state, is remarkably small and lead

vapor is most

certainly NOT a danger. It does NOT emit vapor

as a solid.

Lead compounds can in some cases be absorbed by

the skin, but

metallic lead is not dangerous in that way. The

one real

danger in this list is lead dust from filing,

which is

dangerous to ingest. I fully support warnings

about dangerous

aspects of modeling, but this one "ain't coming

out" correctly.
