Structural blue coating based on glaze painting
Bleu structurel d’origine non pigmentaire obtenu par la méthode des glacis en peinture
Résumé
An art/science collaboration has enabled a contemporary artist to re-discover an age-old technique used by glaze-masters such as Leonardo da Vinci. The process uses dark bitumen, white mineral particles, a brush, and knowledge of drying and laying time to produce intense, structural, blue hues that are mainly due to Rayleigh light scattering. Although these blue hues are mentioned in ancient studio manuscripts, very few are found in actual easel painting masterpieces.
