Deep drawing is an indstrial technique used to make many hollow shapes out of sheet metal. Marcia Selsor did a post a while back on the technique using clay where she draped the clay slab over a sheet with a hole in it and combed the material down into the hole. I wanted to try her technique and it works very well. It is much faster than making a mold and there can be many variations using the same form. I had a commission for a wall nook and this was a proof of concept piece for that nook. As it was I used a more traditional method of fully supporting the bowl because of the size of the piece and its form. I never fired this test piece but I think the technique has a lot of promise and the cross section of the bowl came out very thin which I personally like. I never post pictures of commissioned work because I believe that I do not own the rights to the piece when the sale has been consummated contrary to what courts have recently said.
