This is the first time I've oxidised any of my silver jewellery, so I've used the 'boiled egg' method as I didn't have any Liver of Sulphur. I put the pieces into a plastic bag with a (hot!) chopped up hard-boiled egg, and waited just over an hour to get the effect I wanted. I'm quite pleased with the result - after giving them a good rinse and then a polish to highlight the detail in the wirework. I'm still not entirely sure which I prefer, but it's interesting to see the difference the oxidisation makes!
