In the light of new documentary information regarding the range of materials available to sixteenth century artists, cross sections from paintings were re-examined using scanning electron microscopy - energy dispersive spectrometry. Among a variety of new materials, colored glassy pigments were found including diverse yellow glassy particles, specifically lead silicate and a glass colored by lead antimonate. These are the “yellow smalts” described in Renaissance writings on artists’ materials.
