Long before oil paint existed, painters mixed pigment with nothing more than egg yolk and water, and the result has outlasted almost everything else in art history. Egg tempera dries fast, resists yellowing, and still has devoted followers today.
Egg tempera at a glance
- Egg tempera mixes pigment with egg yolk, usually diluted with water, as its binder.
- It was Europe’s dominant painting medium before oil paint became widespread in the 15th century.
- It dries within minutes, forcing painters to work in small, careful strokes rather than broad blending.
- Once cured, it forms an extremely durable, non-yellowing surface that can last for centuries.
- Botticelli’s “The Birth of Venus” and Andrew Wyeth’s “Christina’s World” were both painted in egg tempera.
Egg Tempera in Questions and Answers
What is egg tempera made of?
Egg tempera is made by grinding dry pigment and binding it with egg yolk, typically thinned with a small amount of water. The egg acts as a natural emulsion that holds the pigment together and bonds it to the painting surface as it dries.
Why did painters switch from tempera to oil?
Oil paint, popularized by Flemish painters in the 15th century, offered a much longer working time, letting artists blend colors smoothly and build up glazes over days rather than minutes. Tempera’s fast drying time, while useful for detail, made the kind of soft blending oil allowed almost impossible.
Which famous paintings were made with egg tempera?
Sandro Botticelli painted both “The Birth of Venus” and “Primavera” in egg tempera in the late 15th century, and much earlier Byzantine and medieval icon painting relied on it almost exclusively. In the 20th century, American painter Andrew Wyeth revived the medium for works including “Christina’s World,” one of the most recognized paintings of the century.
Why does egg tempera dry so fast?
The egg yolk binder sets quickly once exposed to air, often within minutes, which is very different from oil’s slow chemical curing process. This forces painters to apply color in small, careful strokes or thin cross-hatched layers rather than blending wet paint directly on the surface.
Does egg tempera last a long time?
Yes, remarkably well. Egyptian funeral portraits and Byzantine icons painted in tempera-like techniques have survived over a thousand years, and unlike some oil varnishes, tempera does not yellow with age. Its main vulnerability is the rigid panel it is usually painted on, which can crack if not properly prepared.
Is egg tempera hard to learn?
It asks for a different mindset than oil or acrylic, since blending happens through layered strokes rather than pushing wet paint around. Many painters find the discipline rewarding once they adjust, since the fast drying time means a painting can be varnished and framed far sooner than an oil equivalent.
The Dominant Medium Before Oil
Egg tempera was the standard painting medium across Europe for most of the medieval period and into the early Renaissance, used on wood panels prepared with a smooth chalk ground called gesso. Painters built up form through fine, hatched strokes of color, often over a green or gray underpainting used to model flesh tones, a technique visible in many surviving altarpieces from the period.
Sandro Botticelli was among the last great masters to work primarily in tempera even as oil paint was becoming available in Italy. His mythological paintings show how far the medium could be pushed, with delicate, linear detail that later painters working in oil rarely matched in quite the same way.
How Tempera Painters Build an Image
Because each stroke of tempera dries almost immediately, painters cannot blend colors wet-on-wet the way oil painters can. Instead, they build form through many thin, closely hatched strokes of color layered over one another, similar in spirit to the cross-hatching a draftsman uses in pen and ink. Done well, the layered strokes optically blend when viewed from a normal distance, producing smooth gradations from a technique that is, up close, made of many small distinct marks.
This is part of why egg tempera paintings often have an especially crisp, luminous quality, since the many thin layers let light travel through and reflect back in a way similar to glazing in oil.
Andrew Wyeth’s 20th-Century Revival
Egg tempera largely fell out of mainstream use once oil paint took over, but American painter Andrew Wyeth learned it as a young man and made it central to his most iconic work. “Christina’s World,” painted in 1948, uses tempera’s fine, hatched detail to render dry grass and weathered wood with an almost photographic precision, while the medium’s limitations on blending suit the painting’s still, quiet mood.
