- WARNING!
-
At the time this book was written it was common to use lead for many things including heat treating (above), soft anvils and backing up repousse'.
Lead is no longer used for these applications in the small shop or in industry due to toxicity.
Lead should be avoided unless absolutely necessary.
After handling lead one should carefully wash their hands before eating or smoking.
Cloths used while working lead should not be washed with children's clothing.
Salt baths are used for heat treating instead of lead.
However, some heat treating salts have toxicity problems as well.
When soft metal is needed pure tin or zinc can be used to replace lead.
While standard 50/50 tin/lead solders are available new lead free (mostly tin) solders are available for plumbing and can be used for other purposes.
