Art Glossary
A comprehensive glossary of art terms, techniques, movements, and materials. From chiaroscuro to creative coding, find clear definitions for every art concept.
C
Calotype: William Henry Fox Talbot's Paper Negative Process
The calotype was William Henry Fox Talbot's paper negative photographic process, introduced in 1841. Learn how it enabled reproducible prints and shaped photography's future.
Chine-colle: Pressing Thin Paper Into Prints for Delicate Detail and Color
Chine-colle bonds thin paper to a heavier support during printing, adding color and texture. Learn its history, technique, and use by Matisse and Redon.
Cold Pressed Paper (Not): The Versatile Surface Most Watercolorists Choose
Cold pressed paper is watercolor paper with a lightly textured surface, the most popular choice for watercolor. Learn how it works, its history, and why 80% of painters prefer it.
R
Rag Paper: Cotton-Based Paper That Lasts for Centuries
Rag paper is paper made from cotton or linen rags, valued for its archival quality and strength. Learn its history from medieval China to modern watercolor paper and why it outlasts wood pulp.
Rough Paper: The Heavily Textured Surface for Expressive Watercolor
Rough paper is watercolor paper with the heaviest texture, left to dry with minimal pressing. Learn how it creates dramatic granulation, its history, and why landscape painters prefer it.
W
Washi: Japanese Paper Made From Kozo, Mitsumata, and Gampi Fibers
Washi is traditional Japanese paper handmade from kozo, mitsumata, and gampi fibers. Learn its thousand-year history, how it is made, its role in art and conservation, and why it lasts.
Watercolor Paper: The Surface That Makes Watercolor Possible
Watercolor paper is thick, absorbent paper designed for water media. Learn its history, cotton vs. wood pulp fibers, weights from 90 lb to 300 lb, and how to choose the right surface.
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.
