Art Glossary
A comprehensive glossary of art terms, techniques, movements, and materials. From chiaroscuro to creative coding, find clear definitions for every art concept.
I
Impasto Medium: Additives That Thicken Paint for Texture
Impasto mediums are additives that thicken oil and acrylic paint for visible texture. Learn what they contain, how they work, and how Rembrandt and Van Gogh used them.
Impasto: Thick Paint, Visible Brushwork, and Physical Texture
Impasto is paint applied so thickly it catches light and casts shadows. Learn how Van Gogh, Rembrandt, and Auerbach used this textured technique in oil painting.
S
Scumbling: Dry Brush Dragging of Opaque Paint for Texture and Haze
Scumbling is dragging thin broken layers of opaque paint over a darker dry layer for texture, haze, and soft light. From Titian to Turner, learn how it works.
Stippling: Dots for Value, Texture, and Tone
Stippling is the art of building value and texture with dots. Learn its history from Renaissance engraving to scientific illustration and how it differs from pointillism.
T
Texture: The Surface Quality of Art, From Sfumato to Impasto
Texture in art is the perceived surface quality of a work. From Van Gogh's impasto to Michelangelo's polished marble, learn how texture works.
Tooth: The Surface Roughness That Grabs Pigment and Holds It
Tooth is the surface roughness of paper, canvas, or panel that grips pigment. Learn why pastelists, watercolorists, and oil painters depend on tooth for adhesion and layering.
Why an Art Glossary?
Art has always had a language problem. Walk into any gallery and you will hear terms like chiaroscuro, impasto, sfumato, and pentimento thrown around as if everyone knows what they mean. Most people do not. They nod along, afraid to ask, and miss half of what the painting is actually doing.
This glossary exists to fix that. Every entry is written in plain English with real examples: specific paintings, specific artists, specific dates. When we explain plein air, we point you to Monet working beside the Seine in 1873, not a generic definition copied from a dictionary. When we cover creative coding, we start with Casey Reas and Ben Fry at MIT in 2001, not a vague paragraph about "art and technology."
The terms here span centuries and disciplines. You will find Renaissance techniques sitting next to digital art movements, printmaking terminology next to motion graphics concepts. That mix is intentional. Art does not stay in neat historical boxes, and neither does the vocabulary we use to talk about it. A painter working today might need to understand glazing just as much as a 3D animator needs to know what kinetic typography means.
Each definition is a starting point, not a finish line. We write them to be specific enough that you can recognize the technique the next time you see it, but short enough that you can read one in under five minutes. If a term leads you to a painting you had not considered before, or sends you down a rabbit hole about a movement you had never heard of, the glossary is doing its job.
New terms are added regularly. If there is a concept you keep running into but cannot find here, that is a gap we want to fill. The best art terminology does not stay still. It grows as artists invent new ways of working, and the language has to keep up.
