2. Cross-Hatching
Definition: Layering multiple sets of hatched lines at different angles to build darker values and complex textures.
How to Apply:
- Begin with one direction of hatching
- Add a second layer at a different angle (typically 45-90 degrees)
- Add additional layers for deeper values
- Vary pressure between layers for tonal variety
Example Application: When drawing fabric in still life, cross-hatching creates the illusion of woven texture. First layer follows the fabric’s primary weave direction, second layer adds depth, and third layer intensifies shadows in folds.
3. Scumbling
Definition: Loose, irregular circular or random marks that create textured, broken tones without defined edges.
How to Apply:
- Use the side of the charcoal
- Apply in small, random circular motions
- Vary pressure for tonal variation
- Overlap strokes for richer values
Example Application: Scumbling works beautifully for creating cloud formations in landscape drawings, giving them soft, organic edges and atmospheric depth. Also effective for rendering weathered stone or rough tree bark.
4. Blending/Smoothing
Definition: Merging charcoal particles to create smooth, gradual transitions without visible marks or texture.
How to Apply:
- Apply charcoal evenly to the area
- Use blending stumps, tissue, or fingers
- Work in circular or directional motions
- Build gradually from light to dark
Example Application: In charcoal portrait work, smooth blending is essential for rendering skin tones on the illuminated side of the face, creating the soft, realistic appearance of flesh without visible strokes or texture.
5. Stippling
Definition: Creating value and texture through numerous small dots or marks, with density determining the darkness.
How to Apply:
- Hold a charcoal pencil or a sharpened stick vertically
- Make small, controlled dots
- Place dots closer together for darker areas
- Spread dots farther apart for lighter values
Example Application: Stippling excels at rendering subtle textures like porous surfaces, distant foliage, or fine fabric weaves. In a landscape drawing, the stipple technique can create convincing gravel paths or sandy beaches.
6. Lifting/Subtractive Technique
Definition: Removing charcoal to reveal lighter values or the white paper beneath, essentially “drawing” with erasers.
How to Apply:
- Apply charcoal evenly to the area first
- Use a kneaded eraser for soft lifting
- Use a hard eraser for sharp highlights
- Use eraser pencils for precise details
Example Application: This technique is powerful for creating dramatic lighting effects. In a portrait, after covering the entire face with mid-tone charcoal, lift out the highlight on the nose bridge, cheekbone, and forehead to reveal bone structure and light source.
7. Directional Stroking
Definition: Applying charcoal with strokes that follow the contours and form of the subject to enhance the three-dimensional appearance.
How to Apply:
- Observe the directional flow of the subject
- Apply strokes following the form’s curves
- Use longer strokes for smooth surfaces
- Use shorter, broken strokes for textured surfaces
Example Application: When drawing hair in a charcoal portrait, directional stroking is essential. Each stroke follows the hair’s natural growth pattern and flow, creating realistic texture and movement. For a cylindrical object like a vase, vertical strokes that curve around the form emphasise its roundness and volume.
