Our products are made out of recycled copper. They started off life 50-60 years ago as copper hot water cylinders. Since then they have weathered and changed colours depending on the water quality. Also in that time they have been worked on by plumbers and dismantled by scrap metal dealers. So they have the odd dent, scratches or oxidation on them now.This is reflected in our product, each one is unique, with different colours and maybe some flaws. This is typical of recycled art. We have found that lacquering helps to minimise the flaws and improve the colours.
