egg-tempera painting

Egg-tempera painting is a technique that uses pigment ground in an emulsion, most commonly egg yolk, as a binder. The word "tempera" comes from the verb "temper," meaning to bring to a desired consistency. This ancient medium was widely used across various cultures until it was gradually replaced by oil paints during the European Renaissance.12

Tempera was employed on diverse supports, including wood panels for icons and altarpieces, as well as mummy cases and papyrus rolls in ancient Egypt. The process involves preparing a smooth, absorbent surface, typically with layers of gesso. Colors are applied in thin washes, and blending is achieved through techniques like crosshatching. Egg tempera is known for its durability, quick drying time, and luminous quality, resembling modern acrylic paints in handling and finish.12
