'Why does tap water taste different in each country, or do you even have to drink bottle water instead?' Maybe you have been asked yourself this same question. So this is the question I started my research with.
To our naked eye tap water looks like a clean and clear liquid, but every glass of water contains numerous different chemicals. I selected five of those chemicals and used them to oxidise different types of metal.
Oxidized metal surfaces create colours that provide information about a material and its chemical elements. The pallet is a reaction with the base material. Therefore the rings have an organic growth of colour and not every colour is possible on every ring.
The combination of the steel rings and a water jug forms an illustration of the effect of tap water chemicals on metal.
