Explore painting media and techniques, including the behaviour of oil, acrylic, watercolour and ink, and the techniques of layering, glazing, impasto and washes, and relate technique to intention

What this dot point is asking

SEAB wants you to explore painting media and techniques: to understand how the major paints behave (oil, acrylic, watercolour and ink), to know the key techniques of application (layering, glazing, impasto, washes, scumbling), and to relate technique to intention. This is a practical, studio-grounded outcome at the heart of the Coursework component, but it also sharpens the formal analysis of paintings, because understanding how a surface was made deepens the reading of its effect. The central principle is that the medium and the technique are not neutral carriers; they shape the look, feel and meaning of the work, so the artist chooses them to serve an intention.

The answer

The behaviour of the major media

Each painting medium has inherent properties. Oil paint is slow-drying, allowing extended blending, reworking, thick impasto and luminous transparent glazes; it gives rich tonal depth and a long working time. Acrylic dries fast, is water-based and versatile, can be used thin like watercolour or thick like oil, and gives flat, even, graphic colour or built texture; its speed suits layered work but limits wet blending. Watercolour is transparent and fluid, built from light to dark with the white paper providing the lights and the luminosity; it is fresh and spontaneous but unforgiving of overworking. Ink is fluid, decisive and often used for line, wash and calligraphic effect, with strong contrast and little room for correction.

Key techniques of application

Technique is how the medium is laid down. Layering builds an image in successive coats, from underpainting to detail. Glazing applies thin transparent layers over dried paint so light passes through and reflects back, creating luminous depth and rich shadows. Impasto applies paint thickly so it stands off the surface, creating actual texture that catches light and records gesture. Scumbling drags a thin, dry, broken layer of opaque colour over another so the lower layer shows through, softening or veiling it. Washes are thin, fluid applications (central to watercolour and ink) that flood areas with transparent colour for atmospheric or tonal effect. Wet-on-wet lets colours blend on the surface for soft transitions; dry-brush drags scant paint for broken, textured marks.

Ground, support and the role of preparation

The support (canvas, board, paper) and its ground (the prepared surface, often a primer) affect how paint behaves and looks: a smooth ground gives crisp detail, a textured one breaks the stroke. Watercolour relies on the paper's white and texture; oil and acrylic usually need a primed, non-absorbent ground. Understanding the support is part of controlling the medium.

Matching technique to intention

The unifying principle: technique should serve intention. Smooth glazing and blending suit refined, atmospheric, controlled work where the subject dominates; thick impasto and gestural handling suit expressive, immediate work where the surface and feeling dominate; transparent washes suit freshness and light. A skilled artist selects medium and technique deliberately to achieve a particular effect, and a strong Coursework portfolio shows that the technical choices were intentional, not accidental.

Examples in context

Example 1. Georgette Chen's oil technique. The Nanyang pioneer Georgette Chen used controlled oil handling, careful tonal modelling and balanced, slightly muted colour in her portraits and still lifes of tropical subjects. Her measured, refined technique, with smooth transitions and considered surfaces, serves an intention of poise and quiet dignity, demonstrating how a controlled oil method shapes the calm character of the work.

Example 2. Chinese ink-and-wash painting. The East Asian tradition of ink-and-wash, which fed into Nanyang practice, exploits the fluid, transparent behaviour of ink and water on absorbent paper: graded washes suggest mist and distance, while rapid calligraphic strokes capture form in a few decisive marks. It is a clear example of a medium's inherent behaviour, fluidity, transparency, immediacy, directly shaping both technique and expressive effect.

Try this

Q1. Contrast the behaviour of oil paint and watercolour. [4 marks]

• Cue. Oil is slow-drying, allowing blending, reworking, impasto and glazes for rich depth; watercolour is transparent and fast, built light-to-dark with the white paper giving luminosity, fresh and spontaneous but unforgiving of overworking.

Q2. What effect does glazing produce and how is it achieved? [3 marks]

• Cue. Glazing produces luminous, glowing depth and rich shadows by laying thin transparent layers over a dried underlayer, so light passes through and reflects back off the layers beneath.

Q3. Why should technique be matched to intention? [3 marks]

• Cue. Medium and technique shape the look and feeling of a work, so the right handling (glazing for depth, impasto for energy, washes for freshness) achieves the intended effect, while technique applied for its own sake produces incoherent work.
