Mineral pitch drawings
Anne GOYER has developed a pitch-based drawing technique on paper leading to the appearance of pigmentless colors.
The corresponding process has been subject to advanced research from 2015 to 2017 by laboratories in partnership with CNRS (Lumiere Matiere Institute, CNRS - joint research unit University of Lyon, Anne Pillonnet and fellow experts, and in collaboration with ARSAG (Association of Scientific Research for Graphical Arts). A publication is expected in early 2018 in the "Support Tracé" specialist review.
The following works demonstrate the rendering of such technique, notably the appearance of opalescences of blue/green in the area of the eyes without any use of pigments.
