Introduction
When someone types or asks to define tempera they usually want a short, clear idea of what the medium is and how it behaves. This article will answer that and offer practical context for artists, students, and curious readers.
I will cover history, technique, common confusions, and real examples so you can tell egg tempera apart from school-room paints. Short, useful, and precise. Ready?

What Does define tempera Mean?
To define tempera is to describe a family of fast-drying, water-based paints that bind pigment to a surface using a protein or glue binder, most famously egg yolk. Historically, the term often means egg tempera when used in art-historical contexts, but it can also refer to other mixes such as casein tempera or modern poster tempera.
In short, tempera paints are thin, pigmented emulsions applied in precise strokes that dry matte and durable. The finish is different from oil paint and distinct from watercolor or acrylic.
Etymology and Origin of define tempera
The verb phrase define tempera asks for a definition rooted in a long history. The English word tempera comes from the Italian temperare, meaning to mix or temper, a reference to how pigments are tempered with a binder.
Egg tempera as a technique dates back to Antiquity and was dominant in panel painting through the early Renaissance. Artists like Fra Angelico and Botticelli used it extensively before oil painting took over in the 1500s. For a concise background see Tempera on Britannica or the overview at Wikipedia.
How define tempera Is Used in Everyday Language
People ask to define tempera in several everyday ways: as an art student clarifying a technique, a parent comparing classroom paints, or a curator describing a medieval panel. The meaning shifts slightly with context, which is why a clear definition helps.
‘When you define tempera for a class, explain egg yolk as the classic binder.’
‘I asked the instructor to define tempera and she showed us panel painting by Duccio.’
‘My child brought home tempera paint, but the teacher actually meant washable poster paint.’
‘To properly define tempera in a restoration report you need to test for casein or egg protein.’
define tempera in Different Contexts
In art history, define tempera typically points to egg tempera, prized for fine detail and longevity. Conservators and museums test for protein binders to confirm an original’s technique and inform restoration.
In schools and crafts, tempera is often shorthand for inexpensive, water-based poster paints. Those are convenient and nontoxic but not technically the same as traditional egg or casein tempera.
Commercially, the word can label various formulas. If you need archival quality, ask specifically whether the product is egg tempera, casein tempera, or a modern emulsion-based tempera substitute.
Common Misconceptions About Tempera
One common error is using define tempera interchangeably with poster paint. They share water as a carrier, but poster paint often uses synthetic binders and is not as lightfast or durable as true tempera formulas.
Another misconception is that tempera cannot achieve rich color or subtle modeling. Egg tempera layers can produce luminosity and fine gradations, though the technique favors hatching and glazes over thick impasto.
Related Words and Phrases
When you define tempera you will likely encounter related terms such as egg tempera, casein, gouache, and tempera grassa. Gouache is opaque and water-based like tempera but uses gum arabic, not protein, as a binder.
For quick comparisons, see our piece on gouache definition and a deeper entry on egg tempera for technique notes and examples. External references like Merriam-Webster also give concise dictionary definitions.
Why define tempera Matters in 2026
As interest in traditional craft and sustainable art materials grows, knowing how to define tempera helps artists choose safer, long-lasting methods. Museums and collectors also care because accurate labeling affects conservation and market value.
Plus, the revival of historical techniques in contemporary studio practice means that defining tempera is useful for cross-disciplinary projects. Whether you plan a small panel or a large conservation job, the right definition guides materials and expectations.
Closing
If you asked someone to define tempera you now have a clear, usable answer: a family of protein or glue-bound, water-based paints with deep historical roots and varied modern uses. Egg tempera is the classic example, while classroom tempera usually means poster paint.
