Roman sling-bullets

[M. Demetrius]

Let me tell you from experience that it's not something I would recommend! The water in the mould boils instantly and you get a small explosion of moulten lead spewing into the air and onto your hands, and feet!

And then you see the ambulance sign from the inside of the ambulance, so would it be written the right direction? I doubt you'd care that much.

Would dry pottery clay work for a mold? Or should it be fired first?

I'm willing to try it and find out, I think. Maybe make a 4 or 6 cell mold.
