Our porridge pot, only about 4 inches across the top, along with the 6 hammers...some homemade , needed to get it into shape. It is hammered from the inside (!) and requires 5 annealings and just about 3 days work, finishing and cleaning included. Thought you might like to see it.
I am a bespoke coppersmith..I build items as I get orders. One man, one item at a time. I usually have about a 3 month backlog, so plan accordingly. My work is at the technological level of about 1745 or so.Made with a hammer and a file, and the work shows that.
