egg tempera painting

Egg tempera isn’t bought. It’s conjured. The recipe is older than oils, older than acrylics, as old as monks in candlelight.

You’ll need a vessel—glass, small, test-tube-like. Something worthy of holding gold. Crack an egg under a slow trickle of water, let it fall into your palm. Rock the yolk gently back and forth while the stream carries away the whites. Save them if you wish; alchemy wastes nothing.

Now cradle the yolk in one hand and pierce it with the other. Watch as the golden heart spills into your waiting vial. This is the binder: the soul of the paint.

Next comes water. You may choose distilled water, clear and clean. Or water drawn from a hidden spring. Or, if you’re feeling whimsical, the tears of an elf. Whatever your source, mix it in equal measure with the yolk.

To guard against decay, add a drop or two of vinegar—otherwise, in a few days, your creation will reek of rot. Seal your vial and shake it like a sorcerer mixing a potion.

Now awaken the colors. Pigments from the wild, or ground by your own mortar and pestle, or even store-bought powders if that’s your path. Mix them with your yolk potion, and with a brush lay them down on true gesso panels.

That’s it. You’ve summoned egg tempera. Not bought, not borrowed—made. Ancient, luminous, and alive.

Materials You’ll Need

  • 1 fresh egg
  • A small glass vial or test tube
  • Distilled (or clean) water
  • Vinegar (optional, for preservation)
  • Pigments (store-bought or hand-ground)
  • A small brush
  • Panels prepared with true gesso (more on that another time)

Steps

  1. Separate the Yolk
    • Crack the egg under gently running water into your palm.
    • Roll the yolk back and forth until the egg white washes away. You can save the whites or discard them.
  2. Extract the Binder
    • Holding the yolk gently, puncture it with your other hand.
    • Let the liquid yolk pour into your vial, leaving the membrane behind.
  3. Mix With Water
    • Add an equal amount of water (1:1 ratio).
    • Distilled water is best, but spring or even tap water works fine.
  4. Preserve the Mixture
    • Add 1–2 drops of vinegar to prevent spoilage.
    • Seal the vial and shake well until fully blended.
  5. Add Pigments
    • Mix your yolk-water binder with pigment.
    • Adjust pigment amounts until the mixture feels right to your brush.
  6. Paint
    • Use a fine brush and paint over a surface prepared with true gesso.
    • Work in thin, layered strokes—egg tempera dries fast.
