Interference Colours on Titanium: From Science to Art
2022 Art Lecture
The study of interference colors that may appear at the surface of a metallic material goes back to the early XIX century. From that time on other studies followed, focusing in particular on titanium.
Among them the work of Pietro Pedeferri gave rise to the development of a robust technique that permits to obtain beautiful colors on the surface of titanium, while maintaining an engineering control of this technique. Furthermore Pietro Pedeferri used this electrochemical method as a painting technique exploiting a peculiarity of the oxides growth.
The 'memory of titanium', permits the obtaining on the surfaces of pattern and images that reveals the invisible aspects of phenomena that take place on the surface of titanium.
