Abstract
This thesis analyzes an original technique based on the transformation of ash into a self-supporting sheet suitable for charcoal drawing. The process, based on the use of sifted ash and powdered wallpaper paste as a binder, generates a lightweight, porous mineral support with a unique tactile quality, similar to a “combustion skin.” The research examines the technical, aesthetic, and conceptual dimensions of the material obtained, placing it in the context of contemporary art and practices that aim to stabilize ephemeral residues. The ash sheet is interpreted as artificial geology, a sediment constructed by the artist, and as a poetic device that intertwines memory, combustion, and rebirth.
