These are the most beautiful mirrors I have ever seen, I love everything about them, the graphic feel, the geometrical patterns and the colors. These mirrors show the beauty of the natural oxidizing process of mirrors. Dutch designers David Derksen and Lex Pott presented the Transcience mirrors during the Dutch Design Week 2011 in Eindhoven.
Some information from David's website about the process: 'Normally, the oxidation process in a mirror occurs randomly and evolves slowly over time. This process can be regarded as degradation, however this project shows the beauty of this material transition of silver. 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.'
