The lost technique of egg tempera

William Clay gives freely his knowledge of egg tempera.

I can’t believe I get to study the lost art of egg tempera with this guy, William Clay.

He was a student of Peter Hurd

Here is a bit about Hurd and Wyeth

All Mr. Hurd wanted in return was for William to do the same: FREELY train this technique to the next generation.

Supplies Mr. William’s gave freely to each student.
This is the original recipe of the gesso you can buy commercially that you paint on Masonite boards.

Peter Hurd recommended this book about egg tempera. It was translated to English.
