About Fine Silver
Fine silver is also known as pure silver as it is the purest form of silver you can get and will have 99.9% silver. There is no such thing as pure 100% silver as there are always trace amounts of impurities that are virtually impossible to guarantee are removed. Fine silver is used to make bullion bars for international trading and silver investment. It is also used for some silver coins, particularly of the proof quality currency coins and silver rounds (proof coinage was historically made for checking the dies and for archival purposes, but nowadays often struck in greater numbers specially for coin collectors).
As pure silver has very little copper in the alloy is not very reactive and therefore tarnishes much more slowly than Sterling Silver. In general, the higher the silver content the slower the tarnishing. As with any other type of silver, proper storage will help slow down the tarnishing process.
I make my Fine Silver jewellery pieces using Art Clay Silver which is a pliable, aqueous clay that transforms to pure silver when fired at high temperature with an electric kiln, gas torch, or on a gas stove.
The Art Clay Silver is made of fine silver powder mixed with non-toxic binders and water. When fired at the stipulated temperature and holding time the binder burns away and the fine silver particles solidify completely leaving you with a one-of-a-kind 99.9% pure silver piece.
