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. Éditeur : ISTE OpenScience
