Back in the spring I made these beautifully textured, cuttlefish cast wedding rings. The unique markings are left by the cuttlefish bone that the ring is cast from, making each one an individual.
The casting process begins with melting down casting grain, in the case I used 18ct Fairtrade Yellow Gold which is a wonderful warm, yellow colour:
Pouring the Gold:
Using my torch I get the metal up to a molten temperature, rolling it around in the crucible to ensure that it’s moving freely. I then hold my breath and chose a moment to pour it straight into the mould, keeping the heat on the gold all the way:
Cleaning the Cast Ring:
Once free from the mould the ring is fairly rough and edged with little tendrils of metal which escaped the mould as the heat burned the cuttlefish bone away. I file these off easily and then saw away the ‘sprue’, the funnel of metal where the created by the gold entering the mould:
After that I thoroughly sand the inside of the ring, leaving a smooth interior surface suitable for hallmarking and engraving:
This polishes up to a beautiful gloss and I burnish the outside of the ring to bring out that wonderful cuttlefish texture:
