Egg Tempera is an ancient painting medium using egg yolk or a whole egg. It was famously used in Europe for illuminated manuscripts, and was the most common painting medium until it was surpassed by oil paint during the Renaissance. Once dried, egg yolk tempera hardens permanently and can last for centuries.
Here’s a basic recipe to make it yourself!
- One egg
- 1:1 Gum Arabic Solution
- Clove oil or vinegar (optional)
- Pipette or measuring spoons
- Paper Towels
- Scissors or sharp knife
- Whisk or mixing stick
- Tiny spoons or spatula
- Glass grinding plate
Preparing Egg Tempera Binder:
Use as fresh an egg as possible. Break eggshell carefully, letting egg white drip into a bowl. Move the yolk gently between shell halves; don’t break the yolk.
Carefully roll the yolk onto a paper towel. Roll it back and forth to remove all the egg white.
Rolling the yolk to the edge of the towel, place another bowl under it. Pierce it with the knife and let it drain into the bowl. Keep the yolk sac out, and throw it away.
Use pipette to add enough water for a 1:1 mixture and whisk.
Add 1:1 Gum Arabic solution to the yolk mixture and whisk.
Add a drop of clove oil or vinegar to avoid ‘eggy’ odor and prevent mold. (this is optional)
Using the frosted side of a glass plate, add 1-2 drops of your egg mixture with a pipette.
Add a tiny amount of dry pigment and grind lightly with the muller.
Test your tempera– if it dries dull, add more yolk. If it’s too thin or too glossy, add more pigment.
Without added pigment, the yolk mixture lasts 3-4 days.
Mixed with pigment, it lasts until dried, about 2-3 days.
Make sure to wash your brushes quickly after using. Egg yolk gets very hard! (Remember that egg tempera paintings last many centuries…) Olive oil soap is recommended.
