Many of my paintings are built around the colour yellow . The egg as binding medium was already known in antiquity. Then, the egg yolk was thinned with water and added to the paint, then applied on the walls. Later, it was also used on panels. In order to make the egg yolk more liquid, they followed an old Italian recipe and added the juice of young mashed figs.
Egg tempera holds especially well on thin grounds.
It has a flexible soft stroke and a matte finish. When oil paints are mixed with egg, they lose their oiliness. I press the whole egg through a fine sieve and add rectified linseed oil and some clove oil to it. I let this mixture sit for a few weeks in a dark bottle. Before painting with it, I put equal parts of the egg emulsion and water in another bottle and shake it well - the painting medium is finished.
