I bought my first piece of Britannia silver yesterday:
– it’s a lot like Sterling silver but while the Sterling stuff is 925 parts per thousand pure silver (the rest being an alloy of copper etc) Britannia is 958 parts per thousand pure silver.
This means that Britannia is a little softer than Sterling and much more suggestable. It stretches where Sterling might have cracked and is more cooperative for things like ambitious silversmithing and spinning.
So Britannia seemed just the thing when I was struggling to move my pressforming from beautiful, stretchy copper into unyielding sterling silver …
In terms of cutting, annealing and polishing I really can’t tell the difference between the two alloys but for overall stretchiness Britannia wins hands down.
Here’s how I got on with it:
It’s my first silver piece on the new press forms and I’m really pleased with how well it’s come out, now I just need to make some etching/finish decisions and I might have a range ready for the spring!
