By chance, Antonio Arney found, in the mid-1960s, some rusty bolts in his atelier. The color of the rust pleased him; he decided to fix them on the screen that was ending, increased with a glue and, at the end, passed a dark liquid. Thus began to define the language of this self-taught artist, whose creation process consists of finding the materials, testing their resistance, preparing them and, finally, adjusting them. The necessary abstract forms of composition, however, arise from the artist's measured use of colors.
