Egg Tempera, The Luminous Medium,
Koo Schadler, Instructor


Egg tempera painting is as old as the Egyptians, was most famous during the Renaissance, and is becoming increasingly popular with artists today.  Egg tempera has unsurpassed luminosity.  Dozens of layers can be quickly applied in a single session.  Yet the medium also allows for meticulous brushwork and fine, linear details. Egg tempera appeals to both painter and decorative artist alike. 

Koo Schadler is an internationally recognized master of the medium.  In this comprehensive course, Koo leads students through a step by step process to create a small yet exquisite still life painting.  Students learn how to combine pigments and yolk to make fresh paint, sponge on a background, create a splattered granite ledge with incised lettering, render a wild rose, convey the translucent transparency of glass, and paint a butterfly in flight. 

Koo also discusses gesso panels, powdered pigments, finishing a tempera painting, and the medium’s rich, ancient history.  Bonus videos include “Creating a Light Effect”, to increase light and luminosity in paintings; and “Color Attributes”, for greater proficiency in color mixing.  An in-depth booklet and color chart accompany the course.

Koo has taught hundreds of people from around the world how to paint in egg tempera.  This course is open to all levels, including beginners; prior experience in egg tempera or painting is not required.  Students should be aware that to complete the assigned image requires, depending on ability, 12-20 hours of painting time over the course of 4 weeks.  Students may tailor the image (for example, not paint all objects in the still life) to simplify the painting process.
