Making an Icon
Icons have been made using these methods for over
I use either oak or lime panels with supporting trusses at the back - this stops the wood from warping.
Then 15 coats of gesso (rabbit skin glue and ground chalk) are painted over muslin and an optional wooden frame.
This is then sanded down to a 'marble' finish - any dents or scratches will show when gold leaf is applied.
Bole (ground clay and size) is then painted where the gold is to be laid.
Gold is applied using a 'gilder's tip' - this gold is thinner than a human hair!
The gold is burnished to a brilliant shine.
Then the egg tempera paint (egg yolk and pure ground pigment) is applied in many thin layers which slowly build up rich tones.
The icon is varnished when finished.
