Electrum Wedding Rings
I was asked by some friends recently if I could make them some wedding rings from electrum. Electrum is an alloy of gold and silver, and it's incredibly pretty. But it's kind of hard to work - the standard way of making a ring, by folding a piece of sheet or wire and soldering it closed doesn't work. While electrum is very hard, it has a relatively low melting point, so you can't use normal silver solder on it (also, silver or gold solder would show up as a visible join). I have fused a few rings from sheet electrum, but it's very hard to get a clean join - the ring ended up slightly asymmetric , which isn't always a problem but for wedding rings it didn't seem right. So, time to learn how to cast metal. I bought a Delft Clay Casting kit and got to practising. After a few goes I dived right on in to making the rings. It's a fairly simple process but an interesting one. First up, making a wooden former which is slightly smaller on the inside and sli...
