Hello midnight,
I don't think to many people will encounter Lead Pipe.
But for those of you who do, be "Very Careful" with it.
I did a section of the stuff years ago, the plumber who removed it
folded it into about 6" long with about 2 folds.
I let it sit out in the sun for 3 days before melting it down.
There was still moisture trapped inside and when it started melting,
that moisture exploded like a bomb going off. Fortunately I was outside
and not very close to it when it started exploding, lead splatter everywhere.
If I ever see any again I will split it length ways and make sure it's dry.
