[TheForge] RE: Casting; to be or not to be...

Okay.  I'll try the acid test.  AND, I'll be sure my son is very careful about breathing fumes.

Ask the late Paw Paw Wilson how dangerous "brass fumes' (i.e., zinc
fumes) are:  http://www.anvilfire.com/iForge/
He was exposed in an indoors environment.  Outdoors would help a lot,
but the key is not to breathe the stuff.

Pickle an ingot in acid (or put a drop of acid on the ingot).  If the
color changes from "gold" to copper, then it's probably zinc - you've
etched the zinc out of the surface.
