The soul of any painting lies in its binding medium—the invisible hand that holds pigment to surface, generation to generation.
Since the Renaissance, egg tempera has been the painter's secret. The yolk, separated with the patience of a monk, becomes the binder. Mixed with ground pigments, it dries to a matte finish that catches light in ways oil never could.
Fresh eggs, ground lapis lazuli, vermilion, ochre
Separate the yolk from the white with a hollowed quill. Dissolve the yolk in warm water until it reaches the consistency of thin cream. Grind your pigments to a fine powder, then mix a little at a time into the yolk mixture. Test on a scrap of wood. If it flows like honey and dries to a soft sheen, you have it right.
When the Dutch masters wanted depth, they turned to linseed oil. Pressed from the seeds of the flax plant, this oil darkens with age, turning golden brown like old parchment. It carries pigment like a river carries silt, layer upon layer.
Raw linseed oil, turpentine, mastic resin
Heat the oil slowly over a low flame until it bubbles just enough to release its water content. Let it cool, then strain it through linen cloth. Mix one part mastic resin dissolved in turpentine with four parts oil. This creates a medium that flows like silk but dries hard as stone.
Every restoration I undertake begins with understanding these old hands. When I strip away the modern varnish, I find the original tempera underneath—faded, yes, but still holding its ground. The oil layers tell their own story, each brushstroke a decision made centuries ago.
These mediums are more than tools—they are conversations across time.
