Archaeological illustration has its own visual language — a set of techniques developed over centuries to communicate the form, surface texture, and material properties of objects clearly. You don't need to master all of these to start journaling, but understanding them gives you a powerful vocabulary for your sketches.

This guide covers the four core techniques you'll use most often.

Contour drawing is the foundation — it's about capturing the outline and internal edges of an object using clean, confident lines.

What It Communicates

• The overall shape and proportions of the artifact
• The profile (silhouette) that's diagnostic for classification
• Structural features like rims, bases, handles, and joins

How to Practice

1. Blind contour: Without looking at your paper, trace the edge of the artifact slowly with your eyes while your hand follows on the page. This trains eye-hand coordination and forces you to really look.
2. Modified contour: Same idea, but you can glance at the paper occasionally to check proportions.
3. Outline refinement: Start with a light, loose outline, then go over it with a more deliberate line. Vary your line weight — thicker for outer edges, thinner for internal details.

When to Use It

Always — contour drawing is the skeleton of every archaeological sketch. Even a quick 2-minute journal entry benefits from a clean contour.

Hatching uses parallel lines to build up tone (light and shadow). Cross-hatching layers sets of lines at angles to create darker values.

What It Communicates

• Three-dimensional form through light and shadow
• Surface curvature — lines that follow the form suggest volume
• Material smoothness — regular, parallel hatching suggests manufactured or polished surfaces

How to Practice

Start with simple exercises before applying to artifacts:

1. Value scale: Draw a row of small squares. Fill each with progressively denser hatching — from widely spaced lines (light) to tightly packed lines (dark). Aim for 5–7 distinct steps.
2. Curved hatching: Practice hatching that follows the curve of a cylinder. The lines should wrap around the form, getting closer together in the shadow areas.
3. Cross-hatching: Layer a second set of lines at 30–60° to the first. Add a third layer for the deepest shadows. Each layer should be consistent within itself.

Common Materials and Hatching Approaches

Stippling (also called pointillism in art contexts) uses dots to build up tone and texture. It's one of the most important techniques in archaeological illustration.

What It Communicates

• Rough, granular, or porous surface textures
• Stone and ceramic surfaces
• A "neutral" tonal rendering that doesn't imply a specific surface direction the way hatching lines do

How to Practice

Stippling is simple in concept but requires patience:

1. Dot density exercise: Fill three squares — one sparse (light tone), one moderate (mid-tone), one dense (deep tone). Keep your dots randomly distributed, not in grid patterns.
2. Gradient practice: Create a smooth tonal gradient from light to dark using only dots. This is harder than it sounds — the key is gradual, even transitions.
3. Speed stippling: Set a 5-minute timer and stipple a simple sphere. This builds the muscle memory for efficient dot placement.

When to Use It

Stippling is the go-to technique for:

• Flint and chipped stone — the standard convention in lithic illustration
• Rough ceramics — unglazed, coarse-tempered pottery
• Corroded metal — showing the pitted, granular surface of oxidized bronze or iron
• Unworked stone — natural rock surfaces on ground stone tools

Stippling vs. Hatching

A common question: when do you stipple and when do you hatch?

The general convention:

• Hatching for smooth, manufactured, or polished surfaces
• Stippling for rough, natural, or granular surfaces
• Combined when an object has both (e.g., a polished stone axe with a rough butt end)

Cross-sections show the internal profile of an artifact — as if you sliced it in half. They're essential in archaeological illustration and incredibly useful in your journal.

What It Communicates

• Wall thickness of vessels
• The shape of rims, bases, and handles in profile
• Manufacturing technique (wheel-thrown vs. hand-built, cast vs. hammered)
• The relationship between the interior and exterior of an object

How to Draw a Cross-Section

1. Identify the profile line: For a vessel, this is the edge you'd see if you cut it perfectly in half vertically. For a stone tool, it might be a horizontal slice showing the flaking pattern.
2. Draw the external profile on one side of a vertical center line.
3. Draw the internal profile (the interior surface) alongside it, showing wall thickness.
4. Fill the section — the convention is to fill the cut section with solid black. This instantly distinguishes the section from the surface view.

Practice Exercise

Find a mug or bowl in your kitchen. Draw:

1. The external view from one side
2. The cross-section profile, showing wall thickness at the rim, body, and base

This is a surprisingly effective exercise — everyday objects are great practice for the skills you'll use on ancient ones.

Real journal entries rarely use just one technique. A typical artifact sketch might include:

• Contour lines for the overall shape
• Cross-hatching for shadowed areas under a rim or handle
• Stippling for a rough stone surface
• A cross-section alongside the main drawing

The key is intent — choose the technique that best communicates the specific feature you're rendering.

Try these focused exercises to build your technique:

1. Hatching cube: Draw a cube and shade each visible face with differently-angled hatching to show the light direction.
2. Stipple sphere: Render a sphere using only dots. Pay attention to the highlight (no dots), midtone (sparse dots), shadow (dense dots), and reflected light (slightly fewer dots at the shadow's edge).
3. Profile drawing: Find 3 different vessels in your kitchen. Draw only their cross-section profiles, noting wall thickness variation.
4. Texture sampler: Divide a page into 6 squares. In each, attempt to render a different texture: smooth metal, rough stone, glazed ceramic, woven textile, carved wood, corroded bronze.

These exercises transfer directly to your artifact journal entries. Technique becomes invisible as it becomes habitual — and that's when the real seeing begins.
