Tempera
- tool behavior directly shapes mark
- material preparation affects color / edge / durability
- maintenance and safety matter
What makes the subject recognizable
Material practice is an early parameter system: pressure, load, hardness, dilution and surface can be treated like variables in digital tools.
What the work is made with
These materials are not decoration added after the idea. Their weight, stiffness, opacity, manufacturing method or reproducibility help determine what forms are practical.
People and works to connect
Use these names as research anchors rather than a closed canon. The wider context includes workshops, manufacturers, patrons, collaborators and regional variants that a short reference page cannot exhaust.
How the visual system is built
Pressure changes the mark
Move the slider to alter width and opacity. Physical tools add more variables, hair stiffness, paint load and surface tooth, but pressure alone already changes the character of the stroke.
Historical contribution
Material practice is an early parameter system: pressure, load, hardness, dilution and surface can be treated like variables in digital tools.
Tempera: construction and behavior
Traditional egg tempera combines dry pigment with an emulsion based on egg yolk. It is commonly painted in thin layers on a smooth absorbent gesso ground over a rigid panel.
Egg tempera dries rapidly and does not blend wet-on-wet like slow-drying oil paint. Modeling is built through small strokes, hatching and layered color. Properly made tempera can produce an exceptionally durable, matte-to-satin surface.
Optional browser sketch
This small browser experiment visualizes one shape, rhythm, material effect, or process discussed above. It is an illustration only, not part of the historical claim.
