Egg Tempera

The medium of Byzantine icons and early Renaissance panels.

Color
Any pigment — brilliant, matte
Binder
Egg yolk

Mix powdered pigment with egg yolk and water. That's the entire paint.

  • Egg yolk is nature's paint binder — it dries hard and waterproof.
  • Paint with quick, thin strokes; you can't go back over it.
  • Used by Renaissance masters before oil paint took over.

Steps

  1. 01

    Roll the yolk on a paper towel to dry the membrane, then pierce and drain just the yolk into a jar.

  2. 02

    Add an equal volume of water and shake gently to combine — this is your binder.

  3. 03

    On a tile, mull a small mound of pigment with water to a paste.

  4. 04

    Mix pigment paste 1:1 with the egg-yolk binder.

  5. 05

    Paint in thin, quick strokes — egg tempera dries in seconds and cannot be re-wet.

Materials
3
  • 1 fresh egg yolk (separated from white and membrane)
  • Equal volume of distilled water
  • Dry pigment of your choice (earth, charcoal, lampblack, ochre)

Safety

Moderate Risk

Involves dust, mild chemistry, sharp tools, or solvents. Use PPE and ventilate.

Hazards identified
  • Airborne dust — respiratory irritant
Quick checklist
  • Wear an N95 / FFP2 mask when handling dry powders
  • Mix in a tray to contain dust; wipe surfaces wet
  • Work in a ventilated area; keep food and drink out of the studio
  • Read each material's safety data sheet (SDS) before starting
  • Have water, soap, and a first-aid kit accessible

Heuristic guidance derived from listed materials. Always consult each material's safety data sheet (SDS) and a qualified instructor before attempting.

Notes

Lasts centuries on rigid panels. Mix only what you can use in a few hours.
