Hello. I just joined the site. Its great to know something like this exists. I have been researching cast iron jewelry for its oxidized look.. ie the black metal look. I am also looking to experiment with different metals in my jewelry like brass and copper for the different patinas and colors that they can produce. I was wondering if anyone out there casts in iron and/or brass, copper, or bronze. I have waxes of my jewelry that I would like to produce in these metals.
