Kingdom: Lapideum.


“Over time, dark spots start to appear on mirrors. The silver layer is slowly oxidizing under the influence of oxygen and water, thereby showing some of its history. This process can be regarded as degradation, however this project shows the beauty of this material transition of silver.

Normally, the oxidation process in a mirror occurs randomly and evolves slowly over time. These mirrors reveal the different states of this process. In this case, sulphur is used to create an accelerated oxidation process. Depending on the time that the silver is reacting with sulphur, different colour tones can be achieved, ranging from gold to brown, to purple to blue. The states of the oxidation process are being shown in a pattern that consists of the elemental geometric shapes.

In collaboration with David Derksen.” (Pott, 2015)
