It's not just after handling it that you need to worry about. The acid in your
skin will leech trace amounts from the surface, and you'll absorb it through
your skin. You'd need to go out of your way to poison yourself in this manner,
but you could theoretically get lead poisoning just by holding chunks of lead in
your hand for extended periods of time.

Melt? Technically, ABS never actually melts, but it will go through some
serious heat distortion and turn gum-like. Unfortunately, I believe that's just
a bit over the temperature at which ABS will start to loose structural
integrity, and in order for your solder to fill it properly, it'd still need to
be liquid when it lands (which also introduces the risk of solder splatter
burns).

It might, but adding molten solder too fast will counter the effectiveness of
any heat-sinking capabilities.

Screw the availability. If I ever make weighted bricks, I'm getting that stuff
that melts at about 70C. I should be able to just stick some clumps in a brick,
set it in my custom hot-pot double-boiler (never used for consumables), turn it
on until I hear it start boiling, shut the power off, and remove it once it's
cooled down.
