Battery alloy has changed. Not so much lead in them.
Wheel weights now have a lot of zinc. Ruins your lead mix for casting. At least they are marked; “Zn”, I think.
Browsing Home Depot today (in CA). All solder I could find was ‘lead free’.
Lead for casting is still on the web. They ship it in the USPS flat rate boxes (ha ha).
Lead is EVIL, just one of many attack points on the citizen.
It's not evil but you definitely don't want to breath, drink or eat it. It will jack you up.
