I imagine at a high enough temperature, alloys of lead and iron are formed. Little crystals of lead may sit within the iron, which likely doesn’t melt but might allow some lead in. Still, it’d probably be metallic lead rather than the much more bioavailable ionic (salt) form, but I still wouldn’t use it for cooking. Props to OP for testing it.
Someone used it for making bullets. Selling it without disclosure was quite irresponsible of them.
It could have been an estate sale and changed hands a couple times, considering how old these are
I would still clearly mark any cast iron that I used to melt metals.
how? what methods don’t just wash off?
A stamp on the cooking surface is one way I’ve commonly seen it done.
Gouge It with a steel tool.

that’s even a thing? djeebis
Oh yeah. Bullets, fishing lures, etc. It’s pretty common to have one dedicated to lead out here in the rural parts of the US.
Can confirm. Though, I picked up a cheap steel pot from goodwill for this purpose … cast iron was too expensive for my lead melting needs ; )
Cast iron is fairly ubiquitous in Appalachia. 🙂
