So I believe that I’ve posted before on some of the metal working that I’ve down. In particular, I’ve made a few copper bowls at home. You only need a few tools, as you need to heat up the sheet of copper, pound it into a bowl shape and then get it finished. A small propane torch is really all that you need to heat your piece of copper. A ball peen hammer can be used to get the shape. The only thing that you is to figure out is how you are going to get that bowl shape.
