These two small hand made valet trays have been made from discarded aluminium sheets used for an University project. Their recycled nature is exemplified by the number 41, which is the recycling number associated with aluminium products.
The surface has been scratched with a technique that usually is associated with ceramics and leather working, which is called burnishing. This technique requires rubbing a rounded stone onto the object, that, if done on clay, results in a glossy finishing, and it predates the use of glazes. Using this technique on aluminium produces a polished effect where the stone scratches the surface.
The combination of the irregular hammering and the scratch-polishing makes the light bounce in a way very similar to that of the sunlight on the afternoon sea, hence the other part of the name, mari (seas in Italian).
