When I am out walking and taking photos I often end up looking at old rusty bits of metal. I love the different colours and patinas that can be found as they oxidise. So a while ago I decided to see what I could do myself at home with different types of metal. Sometimes I add household chemicals such as salt and vinegar to see how they react. Some are heated with a blow torch. Some are just left out in the garden for a long time. These are all images of copper.
