I use art clay silver to create fine silver jewellery. Fine silver differs from sterling silver in that it is not alloyed with copper. Sterling silver is 92.5 percent pure with an additional 7.5 copper and may be assay marked (hallmarked) as 925. Fine silver, which is what remains when the water and organic binder is burned off in the firing of silver clay is essentially pure silver and may be assay marked as 999. There is no legal requirement to do so unless the piece weighs more than 7.78grammes.
Metal clay can be shaped just like any soft clay, by hand or using moulds and then fired. I mix silver clay with copper clay to create silver inlaid copper creations as well.
I also create concrete and resin jewellery.
