I have recently finished the series of diptychs: DETOXIFY-ME, using egg tempera for the first time and recording the work in progress.
To make the exterior of the fourth diptych: THE CURE FOR MADNESS, I wanted to set a medallion-style copy of Bosch's "Stone of Folly" on a faux-leather background.
In the end I decided that Hieronymous would have to settle for a textured and less than jewel-like tribute.To seal the box, I sprayed the surface with fixative and added a thin, temporary varnish.
As ever with a new medium, I felt simultaneously frustrated by my lack of mastery and excited by the different ways tempera behaves. When making the exterior of the second box, SHOCK THERAPY, I began to play around with scratching into the gesso surface with an old school compass, creating a faux-snakeskin texture, then washing semi-transparent colour into the grooves. I will definitely be using this medium again.
