This is actually made of copper. It’s a pipe end from Home Depot, I think 1/2 inch.
The bottom was quite rounded when purchased. We sanded the heck out of them (a vice and angle grinder would have been better, but I just work with what I’ve got). It’s still not sitting quite flat, but it’ll work for now.
The handles are the eye portion of a hook and eye set. The lid is two circles of foil-covered mat board - one a bit smaller than the other. Having the two sizes keeps the lid from sliding off the pot. And the lid handle is a silver bead.
And of course, it features a lot of super glue. LOL
