Practice question · Multiple choice
A scumble requires an opaque light film dragged across a dark ground, whereas a glaze demands transparent dark paint over a light ground. What practical consequence follows when creating optical depth with these layered marks?
Hints
- How does the required paint consistency and brush type differ between these marks?
- What role does mechanical friction across the ground play in optical layering?
Show the answer
B. A scumble relies on physical bristle drag rather than liquid vehicle flow
Why
Diluting paint with excess medium converts a scumble into a glaze-like wash, whereas scumbling depends mechanically on stiff paint catching on textured underlayers. Blending into wet paint destroys the optical interplay between layers, which requires distinct dry boundaries.
