This time in class, I decided to try my hand at forming a bowl out of copper using a hammer, a stump of wood with depressions in them and a few trailer-hitch like stakes. I ended up very happy! Check it out...
So first off, my teacher gave me a sheet of 20 gauge copper. I measured it to be 6" square and took it to the huge step sheer and it sliced it like butter! (pic 1 & 2) I then found the center and made a small depression to mark the middle. (pic 3) I scored a circle into the copper using a divider and then I took it to another big sheer and carefully sliced off most of the excess metal, leaving me with a 6" circle. (pic 4)
It was now ready for me to anneal it to get it soft. Then I could hit it with a hammer!
I started hitting the edge first with the help of a depression in the stump. (pic 1 & 2). As I go around slightly on the depressions edge I hammer the copper to move the metal out and shape. (something like that..lol!) I am still learning it, so my explanation is not that of a professional. lol!! But by hammering in a circle, spiraling into the center a bowl is formed! (pic 3 & 4). Here is a video showing the raising process. The black is from the annealing process which leaves oxidation. It was getting hammered off and making cool patterns while doing so.
After annealing it a few more times and then hammering it more the oxidation patter changed. The bowl was taking more shape now. I was hammering to get big dents out and also experimenting with the other depressions on the stump. Some were deeper or smaller in diameter. I found it curled the edges too. It was fun to play around like that. Copper is nice to us that way. lol!!
Here's the final look! I was able to polish the backside with the polishing machine, but the inside I will have to finish by hand. I love it! I think I might try my hand at smaller ones. You can tell I'm pretty happy in this video. lol!
