Understanding Tempera: A Timeless Artistic Medium
When you walk through the halls of an art museum, you are likely looking at centuries of history captured on canvas and wood. Among the oldest and most vibrant techniques you will encounter is tempera. While today we often think of acrylics or watercolors, this ancient medium held the art world together for hundreds of years. Whether you are an aspiring artist or a history buff, understanding this unique paint helps explain how some of the world's most famous masterpieces have remained so bright after nearly two thousand years.
What is Tempera?
At its core, tempera is a fast-drying painting medium. Unlike modern paints that use synthetic polymers, traditional tempera is made by mixing colored pigments with a water-soluble binder. The most common binder used throughout history is egg yolk, which is why you will frequently hear artists refer to it as egg tempera. The name itself comes from the Latin word temperare, which simply means "to mix" or "to bring into due proportion."
Key Characteristics
- Durability: Because of the way the egg yolk cures and hardens, tempera paintings are incredibly resistant to aging.
- Vibrancy: The colors remain bright and clear for centuries, rarely yellowing or fading over time.
- Texture: Tempera dries very quickly, which means artists cannot blend colors as easily as they would with oil paints. Instead, they often use thin, layered strokes to create depth.
- Surface preference: It works best when applied to rigid surfaces, such as carefully prepared wooden panels, rather than flexible canvas.
Usage and Grammar
The word tempera functions as a noun in English. It can refer to the paint itself or the specific style of painting associated with it. When using the word, you can treat it as an uncountable noun.
Example sentences:
- Many of the religious icons from the Byzantine era were created using traditional tempera on wooden boards.
- The student mixed the dry pigments with egg yolk to create her own batch of tempera for the art project.
- Before oil paints gained popularity in the 16th century, most major works in Europe were executed in tempera.
- I love the matte, luminous finish that tempera gives to a painting.
Common Mistakes
One common mistake is confusing tempera with "poster paint." In many school settings, teachers provide inexpensive, water-based paints often labeled as "tempera." However, this modern school paint is typically made with starch or synthetic binders, not the traditional egg-based formula used by Renaissance masters. While they share the name, the durability and professional quality of genuine egg tempera are far superior to the washable paints found in a classroom.
Another point of confusion is the application process. Because tempera dries almost instantly, beginners often struggle because they try to blend colors on the painting surface. Remember: you cannot "push" tempera around the way you can with oil paint. It requires a more patient, layered approach.
FAQ
Is tempera the same as oil paint?
No, they are very different. Oil paint takes days or weeks to dry, allowing artists to blend colors smoothly. Tempera dries in minutes, requiring a style that relies on thin, overlapping lines.
Can tempera crack?
Yes. If tempera is applied to a surface that is not rigid—like a flexible canvas that moves or bends—the paint will eventually crack because it dries into a very brittle, hard film.
Why do people still use tempera today?
Modern artists are often drawn to tempera because of its unique, luminous look and its archival quality. It is a favorite for those who want their work to stand the test of time.
Conclusion
Tempera is more than just a type of paint; it is a bridge to the past. By understanding its origins in egg-based mixtures and its strict, fast-drying nature, you can better appreciate the technical skill of the artists who came before us. Whether you are studying art history or picking up a brush to experiment with new mediums, this versatile and historic paint remains a fundamental part of the artistic toolkit.
