Egg tempera! A time honoured technique. Many artists have at least played with egg tempera, even if they later chose a more modern and convenient medium. Karen Chernick at Hyperallergic has an article on how to source the very best egg you can for making your paints.
…But there’s also a centuries-old artistic tradition of painting using the eggs themselves. Egg tempera was a ubiquitous technique during the early Italian Renaissance, when it was considered the standard for portable easel paintings. Botticelli, Raphael, and Andrew Wyeth all painted with tempera. Today, the quick-drying medium, which employs a 50/50 blend of egg yolk and color pigment, is mostly in use by a brave few contemporary practitioners (who must not mind the smell of aging eggs in the studio).
