Egg yolk tempera: technique
Egg yolk tempera is a particular colored mixture based on yolk of the egg (the white and even the membrane are discarded) joined with natural powdered pigments such as vermillion. The results is a particular tempera whose density depends by constant proportion of yolk and water.
