What's the Diff - Argentium or Sterling?

There's a (relatively) new kid on the block when it comes to silver, and its called "Argentium". It's use is spreading due to it's tarnish resistant nature. I've heard people go so far as to call it superior to traditional sterling silver, but in my mind, it is not superior - only different.

Traditional sterling silver is an alloy of 925 parts silver to 75 parts (usually) copper. This helps to provide some strength to the metal, as pure silver is quite soft. The copper though, also helps to tarnish the metal. Personally, I love sterling silver that gets some black in the grooves of the piece because it really helps enhance the details but many people like their metal bright and shiny.

Argentium is also an alloy, but one made of silver and germanium. It is resistant to tarnish and cleans up quite nicely, often just in a warm soapy bath. I find if I leave it out and exposed to air it goes a kind of goldish, brassy colour. What is important to me in the difference between these two metals is their applications - what I do with them and how come I choose that particular one for the job.

When using the torch to ball up the little end of the metal for use as headpins, nose jewellery, the little bud earrings I make, or the ball end earwires I often use, I choose which one based on what I want the outcome to be. Argentium makes very smooth, fluid little balls, whereas traditional sterling makes little balls that are slightly pitted, or cratered. In the photos below, the first photo shows earrings made with Argentium, and the second shows traditional sterling - see the difference?

If I'm going for a smooth sleek look, I'll choose the Argentium, but if I want something a little more earthy and organic looking, it's traditional sterling silver hands down every time.

Fusion

I managed to fuse a copper circle the other day after many failed attempts. I wasn't really sure what I was doing right or wrong. Sometimes the ends of the wire balled up on me; an outcome I really didn't want. And other times, the wire simply didn't fuse - it got really, really black and it didn't 'become one'. I kept practicing and trying. Over and over and finally, I got it! A lovely circle. What I did was form the circle, overlapping the ends by about 4mm, and then I hammered it flat so the ends were really meshed together. I then fluxed the whole thing and lit the torch to it on a really high flame. Success! It fused.

Today I played with sterling silver fusion, which is SO much easier. This time I didn't flatten the circles, I simply used a dowel to wrap my circle around, and cut them out; again, leaving about 4mm of overlap. I positioned the circle so that the cut ends of overlap touched each other very tightly. I put it on my soldering brick (simply a heat resistant brick found in the hardware store - buy the ones they put into woodstoves or the bottom of a fireplace), and put flux on the whole thing using a small paintbrush. Flux is available from your jewelry supply stores and is essential for fusing and/or soldering. I lit the torch and turned it up fairly high and made the metal red hot, focusing the flame on the place where the two ends touched. The hottest part of the torch is just past the blue flame. I watched closely as the metal got all beautifully liquidy and voila! joined to each other to form a fused circle. I was entirely fascinated by the process. I discovered that sterling is easier to fuse than copper and I found that it just takes practice.

Thanks for reading. Pictured is a pair of earrings I made.
