My sister and her family bought me a silver clay set for xmas and I have been playing with it today. I LOVE IT. I made a bead and some charms all 99.9% silver.
You make the item out of the clay then fire it and you then burnish it and you have your finished project.
I really enjoyed it and cannot wait to make some more, I have a copper and bronze set coming to so have a look on our Etsy store. I will let you all know when it comes and show you what I come up with.
