I finally used it this weekend to take a Water-Casting jewelry class. Basically, you melt down metals (silver, copper, gold if you are lucky) in a crucible using a very, very hot torch. Once the metal is molten you dump it into a pot of water. That is it! I got to dump it into a can of water and broomsticks. Yes, broomsticks. It created some really rad shapes. Here is a basic tutorial I found online.
I volunteered to go first because the rest of the class was scared. It was a really big torch (That's what she said! --OFFICE JOKE, can't help myself). I've had some experience with metal-smithing and water casting so I thought I could go first. My first attempt went well and this is what I got:
This pieces is a 50/50 combination of sterling silver and copper.
On my second attempt, I got this:
This piece has more copper in it, about a 40/60 combination. I added a pearl on this one too.
If I access to a torch again, I would totally make more. It was a lot of fun and really easy.
