Tempera is a paint made by binding powdered pigment with egg, most often just the yolk, thinned with water into a fast-drying, quick-handling medium. Unlike oil paint, which stays workable for hours or days and blends smoothly on the surface, tempera sets within minutes, which makes broad blending nearly impossible — painters instead build form and color through many thin layers of fine, closely spaced hatched or cross-hatched strokes.
The egg binder dries to a tough, matte film that resists yellowing and has proven remarkably stable over centuries, which is part of why so many tempera panels survive from the medieval and early Renaissance periods in vivid condition. Painters reach for tempera when they want crisp, luminous, precisely controlled color and linear detail, rather than the soft blending and rich, buttery texture that oil painting offers.
How to spot it
- 01Fine, closely spaced hatched or cross-hatched brushstrokes building up form.
- 02Crisp, precise edges and detail rather than soft blended transitions.
- 03A matte, slightly chalky surface with luminous, jewel-like color.
- 04Colors that stay remarkably bright and unyellowed even on very old panels.
- 05Egg tempera works often on wood panel, sometimes with gold leaf backgrounds.
The Tempera workshop card
Many short sessions over weeksMaterials
- fresh egg yolk as the binder
- dry powdered pigments
- distilled water for thinning
- a gessoed wood panel as support
- fine round sable brushes for hatching
- a palette knife for grinding pigment into the yolk
Steps
- 1
Prepare a gessoed panel
Work on a smooth, absorbent gesso ground over a rigid wood panel — tempera needs a stable, non-flexible support since it can crack on canvas over time.
- 2
Mix pigment and egg yolk fresh
Grind dry pigment with a small amount of water into a paste, then blend in egg yolk in roughly equal measure, mixing only as much as you'll use that session. Wear a dust mask and avoid raising powder — many dry pigments are toxic to inhale.
- 3
Thin to a workable consistency
Add water gradually until the paint flows smoothly off the brush without pooling — too thick and it won't lay down evenly, too thin and the color goes weak.
- 4
Build form with hatched strokes
Apply color in fine, closely spaced parallel or cross-hatched strokes rather than broad washes, since tempera dries far too fast to blend smoothly on the surface.
- 5
Build value in thin layers
Build up value gradually through many thin, semi-transparent layers rather than trying to achieve full color and finished value in a single, hurried, unplanned pass.
- 6
Dry each layer fully
Tempera sets within minutes, so work in small sections and let each hatched layer dry fully before crossing it with another, keeping the strokes crisp instead of muddy.
- 7
Mix fresh pigment each session
Mixed tempera doesn't keep well; prepare only what you need for that session's work, since old, dried-out mixture won't flow smoothly or bond properly anymore.
Classic mistakes
Trying to blend like oil paint
Tempera dries too fast for soft blending on the surface — attempting it just drags and smears half-dry paint. Build form with hatching instead.
Mixing too much at once
Egg tempera doesn't store well once mixed; a large batch dries out or spoils before it's used. Mix small amounts and remix as needed.
Painting on a flexible support
Canvas flexes over time and can crack a brittle tempera paint film. Rigid, gessoed wood panel is the traditional and more stable choice.
Layers too thick
Applying tempera too thickly causes it to crack or flake as it dries. Keep every layer thin and semi-transparent, building depth gradually.
Where it comes from
Egg tempera was the dominant panel-painting medium in Europe through the medieval period and into the early Renaissance, prized for its precision, durability, and luminous color, especially on gessoed wood panels often paired with gold leaf backgrounds. Painters built up flesh tones, drapery, and detail through countless thin, hatched layers, a slow and exacting process well suited to devotional images meant to be studied closely. Tempera began losing ground to oil paint during the 15th century, as oil's slower drying time and blending capacity offered painters more flexibility for soft transitions and atmospheric effects. It never disappeared entirely, and saw a notable revival among 20th-century American realist painters drawn to its precision and matte finish.

To evoke tempera in an AI generator, describe 'egg tempera painting,' 'fine hatched brushstrokes,' or 'crisp linear detail on wood panel.' Add 'luminous matte color,' 'jewel-toned pigment,' or 'precise cross-hatching' to signal the medium's characteristic buildup. Mentioning 'gold leaf background' or 'gessoed panel surface' reinforces the historical panel-painting look. Avoid 'soft blending' or 'buttery brushwork,' which pull toward oil painting instead of tempera's crisp, dry precision and fine linear detail.
Frequently asked questions
What is tempera paint made of?
Traditional egg tempera binds powdered pigment with egg yolk, thinned with water. It's different from modern 'poster tempera' or gouache, which use other binders entirely despite sharing the name.
Why does tempera dry so fast?
The egg binder sets quickly once exposed to air, within minutes rather than the hours or days oil paint stays workable, which is why tempera is built with fine hatched strokes instead of blended.
Can I blend colors in tempera?
Not on the surface the way you would in oil. Colors are built up optically through layers of fine hatching, letting the eye blend adjacent strokes rather than physically mixing wet paint.
Does tempera last as long as oil painting?
Very well, in fact — many egg tempera panels from centuries ago survive with remarkably bright, unyellowed color, since the egg binder forms a tough, stable film over time.
