A botanical-dyed aluminum mobile made by dyeing aluminum with plant dyes that have a low environmental impact. This mobile is made of three triangles. The aluminum frame is the largest and lightest part, a small steel block maintains the overall balance, and a wood base supports both the frame and the block. The proportions of these three triangular parts are all the same. The rhythm and balance created by the three different materials of the triangle create a soft and calm time as if you were sailing on the ocean. The balance is adjusted so that the base of the aluminum frame is horizontal. The balance point supported by the pillars is different for each one. ■About Botanical-dyed aluminum I think many people will be surprised to know that aluminum can be dyed. We used plant-dyed dyes in a technique that adds color by filling the holes in porous aluminum that has been anodized and sealing the holes. Botanical-dyed dyes are dyed by extracting pigments from plants.
