I hadn’t etched for a long time, and I’d forgotten how enjoyable the process is. It starts with a sketch – in this case a butterfly – which is turned into a black and white digital image and the colours are inverted. This is then laser printed onto a special type of paper (usually used for printing circuit boards!) and ironed onto a sheet of silver. Next it is dipped into a warm bath of ferric nitrate, which eats away any of the silver not covered by the printed image. Around half an hour later, the silver is washed, scrubbed with wire wool, cut, filed, shaped and then finally loops can be soldered on and chain attached. After a final polish, the butterfly necklace is ready to flutter to a new owner!
