Talking about art nowadays refers to different perspectives, from those that emphasize concept and action to those that postulate the realization of an artistic object. The washi zokei is located in the latter, where material, technique and idea constitute an indivisible third that corresponds to the artist's intention of expression. The term washi zokei refers to three concepts, handmade paper, the procedure to make it and the expressive work resulting from this process; in this book the three aspects are highlighted: materials used in the elaboration of the paper, the perceptual process that accompanies it and the qualities of these factors that contribute to generate an aesthetic experience before the resulting expressive work. The washi zokei is a means of plastic expression that arises in the very conception of the work. The reflection on the physical particularities of the materials, the connotations attributed to them, the dialogue that the artist establishes with them through the precision or imprecision of their movements in the process of elaboration of the work, provide another way of understanding and feeling the internal language of a washi zokei, as an artistic proposal.
