I made this video to show more of what I'm seeing while I make a hammered Copper ring. The first video I made has a voice over and mostly a top down view from a static camera. Hopefully this will help make things a bit clearer.
Thanks for watching! Honestly...the best media I've found for getting that type of matte finish is small to medium sized aquarium gravel. I know it seems weird, but it's the best..especially when you factor in cost. Natural or white won't discolor the metal.
