Egg yolk. Tempera is a type of paint that uses egg yolk as a binding agent to hold together the color pigments.
Not too much anymore. Tempera used to be made with an egg base to help bind the pgment. Poster paint is a water-based synthetic. However, I would say that today most tempera is probably synthetic as well.
It's painted with "tempera", water and egg based paint.
Egg tempera requires another ingredient besides egg yolk and pigment to prevent it from drying too quickly. This other ingredient could be vinegar or wine.
Egg tempera is a terrific medium with many advantages. It is safe, non-toxic, and permanent. Unlike oil paint, it will not yellow, change in color, or grow transparent over time. Unlike acrylic, it has a proven track record going back hundreds of years. Egg tempera shows the beauty of pigments off to great advantage. Colors are clear, bright, and pure.

It was the artists painting medium favored by such Masters as Michelangelo. More recently it has been popularized by artists such as George Tooker and Andrew Wyeth. In it's simplest form egg tempera is a type of paint that is made from dry colored pigments, egg yolk and distilled water. The paint dries fast and is very brittle. It must be painted thinly and in short strokes and must be painted on a rigid absorbent surface.

Egg Tempera is the oldest paint known. A mixture of powdered pigmentation and egg yolk.
Egg yolk is used for making ink because it is permanent. Egg yolk is also used to create tempera paint because it allows for a glossy look when it dries.
Egg yolk by itself dries up and cracks, but in the middle ages it was very popular to create a yellow color for a paint. To create this paint (called Tempera) the egg yolk would be added to oil on a 1:1 basis. The two substances become a solution, and the oil keeps the egg yolk in a consistency we think of with paint (thick and viscuous). Some sort of acidic substance is also added usually, like vinegar or white wine. When the tempera is used for painting, it dries quickly, and the oil causes the pigment in the egg to bond with the surface that is painted. See the related link for examples of Tempera art.
The invention of oil paint was revolutionary in the Northern Renaissance. Prior to then, everyone was painting with egg tempera. Check out Arnolfini's Wedding by Van Eyck.
You may be referring to portraits made in "egg tempera." Egg Tempera was a European method of painting that used ground pigments mixed with egg and applied in fine thin layers. Egg Tempera portraits are most always small in size and rendered in fine and delicate detail. Many will crack over time.
