Patination
The term patination can be defined as the effect that can be produced by exposing certain metal materials (such as bronze or iron) to specific chemicals (such as vinegar, salt and hydrogen peroxide). The purpose of patination is to intentionally replicate the glossy colour and appearance - as well as the protective finish - of a natural patina that would otherwise occur over a period of time.
Patina is a layer of aged or corroded material that can appear on surfaces over time due to oxidation, exposure, use and so on. The appearance of patina over time can sometimes enhance the aesthetic quality of surfaces that might otherwise appear too intentional or manufactured, rather than individual and crafted.
