What is Argentium Silver?

Argentium Sterling Silver is a patented and trademarked alloy that is at least 92.5% pure silver like regular sterling silver. What makes it different from regular sterling silver is that a small amount of germanium replaces some of the copper that is usually the other 7.5% of a sterling silver alloy. Peter Johns, a professor of silversmithing at Middlesex University in England, invented it in 1996.

The main advantage of working with Argentium Sterling Silver is that it is not subject to firescale like normal sterling silver. Although it does oxidise like sterling, this is easily removed by pickle. It is also more resistent to tarnish than sterling.

What is the best way to store syringes so they don't dry out?
There are a variety of ways to store metal clay syringes to ensure they don't dry out. You can store them standing in a small cup of water with the tip or nozzle down in the water. This prevents air from getting into the nozzle and drying the clay. Using cling film or Saran Wrap over the end also stops air getting to the clay and drying it out. A small piece of silver wire inserted into the nozzle can also prevent drying although it needs to be a good fit and it's best to also wrap this in cling film or put it back in the sealed packet it came in. Don't use a steel pin to seal it, steel reacts badly with the clay....
