Egg tempera

A tempera paint that predominantly uses egg yolk as a binder. Commonly used in calligraphy and Byzantine Icons, egg tempera enables the user to make more intricate detailing than most paints. It cannot be mass produced because it of its short life span-- in a refrigerator it can last about half a year if the container is absolutely air-tight. Egg Tempera emulsion recipe: ~one part egg yolk (roll it around in your hands until the sack is dry enough to remove) ~half part water ~half part vinegar (an optional drop of clove oil to combat the vinegar smell, if that's your thing)
