This project combines design and materials science. The author’s goal was to make full use of ash, which is usually treated as waste – and create a new type of material. As he was doing his research, he experimented with the amount of the ash used and tested various kinds of clay as a binding material. As a consequence, he created a material containing 70% of waste. Moreover, the author examined the physical parameters of the material in cooperation with the Faculty of Materials Engineering and Metallurgy at the Silesian University of Technology. In result, he was able to develop diamond-shaped tiles: the newly created material was then dyed and naturally shaped by means of joining clay and ash. Another part of the project was the presentation of particular stages of work on the new material.
