Foundational Rules of Oil Painting
The 3 Core Rules of Oil Painting
Fat over Lean: What it means and why it matters
In oil painting, the rule of fat over lean is essential. This principle dictates that you start with thin layers that contain more solvent and less oil.
As you build up layers, increase the oil content. This ensures a stable and crack-resistant painting, allowing the lower layers to dry faster than the top layers.
Thick over Thin: Layering to avoid cracking and maintain texture
Layering thick over thin means applying thinner, more fluid paint layers initially, followed by progressively thicker applications.
This helps in achieving texture while preventing the underlayers from drying slower than the top layers, which can cause the paint to crack. Using techniques such as underpainting and impasto ensures durability and adds texture.
Slow-Drying over Fast-Drying: The drying process and its impact on the painting
The rule of slow-drying over fast-drying addresses the necessity of applying slower-drying paints over faster-drying ones.
Oils like linseed oil dry slowly and should be used in upper layers. Faster-drying mediums like turpentine are ideal for initial layers. This method prevents the painting from cracking as it ages.
Building Blocks: Fundamental Techniques Every Artist Should Know
Chiaroscuro – The Play of Light and Dark

Chiaroscuro, a technique rooted in the Renaissance, focuses on the stark contrast between light and dark. It exploits light and shadow to create drama and depth, shaping the perception of forms. It dates back to the works of Rembrandt and Caravaggio.
How to create drama and depth using this technique
To apply chiaroscuro, deliberately place intense darks next to highlights. Use color theory to balance your tones. This method accentuates form and volume, creating a three-dimensional effect on a two-dimensional plane.
Examples from Renaissance artists like Rembrandt and Caravaggio
Rembrandt and Caravaggio masterfully utilized chiaroscuro. Their paintings reveal intricate details in illuminated areas while the surroundings fade into shadows, emphasizing the focal points.
Scumbling – Adding Texture and Depth

Scumbling involves applying a semi-transparent layer of light pigment over a dry, darker layer. Use a stiff brush to drag the paint, creating a textured, veiled effect. This technique unveils the underpainting while adding a luminous quality.
The effect of revealing underpainting for a textured finish
Scumbling highlights the texture by partially revealing the layers beneath. The juxtaposition of thin, light strokes over darker hues offers a vivid, textured appearance. Turner’s landscapes and works of the Impressionists exemplify this.
Famous examples: Turner and Impressionists
Turner used scumbling to create atmospheric effects, while the Impressionists employed it to add spontaneity and texture to their paintings.
Alla Prima – Wet-on-Wet Painting

Alla prima, or wet-on-wet, involves completing a painting in one session. Apply layers of color without waiting for the underlayers to dry. This method captures immediacy and dynamism.
Techniques for applying colors in a single sitting
Mix your colors in advance and work swiftly. Use broad strokes with a palette knife or hog bristle brushes for bold effects. The key is to maintain confidence in your strokes and color choices.
Notable artists using Alla Prima: Van Gogh and Monet
Van Gogh and Monet were masters of alla prima, producing works with vivid energy and spontaneity unmatched by other techniques.
Glazing – Layering Transparent Colors

Glazing involves applying thin, transparent layers of paint over a dry layer. This technique enhances the depth and richness of colors, creating a glossy, multi-dimensional finish.
Creating a glossy, multi-dimensional finish
Mix a small amount of pigment with a medium like linseed oil. Apply delicately using a soft brush. This builds luminous surfaces with intricate, deep colors. Controlling each layer’s transparency is key; avoid muddiness by allowing layers to dry thoroughly.
How to control transparency to avoid muddy colors
Regulate the medium-to-paint ratio for precise transparency. Allow each layer to dry completely before adding the next to maintain clarity and vibrancy.
Underpainting – Sketching the Foundation

Underpainting sets the tonal values for the artwork, creating a monochrome map of the final composition. This foundational layer guides the addition of colors and details.
Using a monochrome layer to set the structure of the painting
Typically, an underpainting employs shades of a single color, such as burnt umber, to establish shadows and highlights. This helps in visualizing the light and shadow interplay before adding complex colors.
Examples of artists who use underpainting (Jan Van Eyck, Giotto)
Artists like Jan Van Eyck and Giotto utilized underpainting to establish realism and depth in their works, creating solid groundwork for their vibrant oil layers.
Impasto – Textured Strokes

Impasto involves applying thick paint with a palette knife or brush, creating pronounced, textured strokes. This adds physical dimension and dramatic emphasis to the painting.
How to use a palette knife for bold, textured areas
Load the palette knife with paint and apply it to the canvas in deliberate movements. The strokes should be confident, adding a tactile dimension that stands out visually.
Iconic examples: Van Gogh’s bold use of Impasto
Van Gogh’s impasto technique is instantly recognizable, with bold, swirling strokes that give his pieces an almost sculptural quality.
Grisaille – Monochrome Painting for Shadow and Light

Grisaille uses shades of black, white, and gray to depict form and depth. Often used as an underpainting, it can also stand alone as a monochromatic piece.
Using Grisaille for underpainting or standalone works
When used under color layers, grisaille offers a detailed guide for light and shadow. Alone, it presents a strikingly stark representation of subjects.
Historical significance and modern-day applications
Traditionally employed by artists like Giotto for frescoes, grisaille has modern-day relevance in creating detailed studies or as a preliminary step in multi-layered oil painting techniques.
Advanced Techniques for Experimentation
Blocking In with a Palette Knife

A palette knife allows for bold application. Load the edge with paint, then press it onto the canvas. Drag across the surface to create textured, abstract effects. The control over edges and lines makes it ideal for dynamic compositions.
How to create abstract effects and textures
Use the broad side for large areas, the tip for fine lines. Scraping motions can reveal layers below. This adds depth and complexity, essential for abstract pieces. Maintain clean edges and manage broken lines by alternating between different knife angles.
Managing clean edges and broken lines
Clean the knife frequently to avoid muddy colors. For sharp edges, press firmly; for softer, more broken lines, use a lighter touch. Experiment with pressure and speed to achieve desired effects.
Sfumato – Soft Transitions Between Tones

Sfumato is about blending tones seamlessly. Use a soft brush and minimal pressure to transition between light and dark areas. Leonardo da Vinci perfected sfumato to create a smoky, ethereal effect in his works.
Examples from da Vinci and other Renaissance masters
Da Vinci’s Mona Lisa is a prime example, with its smooth transitions and soft shadows. Apply tiny, circular motions to blend colors until no harsh lines are visible.
Blending light and dark areas for a smoky effect
Layer translucent glazes for gradual transitions. This avoids the sharp contrast, creating softer, more natural shifts in tone. Achieve a three-dimensional, lifelike appearance.
Sgraffito – Scratching Layers for Texture

Apply thick paint layers, then scratch through to reveal the base color. Use tools like knives, toothpicks, or even combs. This technique adds dynamic, textured contrast.
Tools used for Sgraffito (knives, toothpicks, etc.)
Experiment with various tools for different effects. A fine needle creates delicate lines, while a knife produces broader, more dramatic strokes. Layer colors strategically for more vibrant results.
How to build texture and contrast in the final artwork
Contrast is key. Scratching through lighter top layers to reveal darker underpainting, or vice versa, adds interest. The juxtaposition of textures enriches the visual experience.
Transitional Blending – Creating Gradients and Smoothness

Achieve smooth gradients by blending wet paints with a dry brush. Use circular motions for seamless transitions. Knives can help spread and merge colors effectively.
Using knives and dry brushes to achieve seamless blending
A dry brush softens hard edges, while a palette knife spreads paint smoothly. This combination allows for precise control over gradient creation, making transitions appear effortless.
Techniques for smoothing out oil textures
Lightly drag the knife or brush across the surface, blending the edges of each stroke. This technique ensures smooth transitions without losing texture, crucial for realistic depictions.
Dry Brushing – Light Application of Paint

Dry brushing applies minimal paint to a dry surface. Load a small amount on a stiff brush, then drag gently over the canvas. This highlights textures and introduces subtle shades.
How to apply minimal pigment for texture control
Use a nearly dry brush and build up layers slowly. This method controls pigment distribution, adding delicate highlights and shadows without overpowering the base layers.
Examples of creating a “smoky” or soft appearance
The Impressionists often used dry brushing for its soft, almost dreamy effects. Apply light, feathery strokes for an ethereal look, enhancing the overall texture and mood.
Additional Techniques to Elevate Your Work
Fat over Lean – Managing Layers to Prevent Cracking

Fat over lean is critical. It prevents cracking by allowing each layer to dry properly. Thin initial layers (lean) have less oil, while subsequent layers (fat) contain more oil. This ensures flexibility in upper layers, avoiding cracks.
How to gradually increase oil content for durability
Start with less oil, using turpentine or odorless mineral spirits to thin your paint. As you build layers, increase the amount of linseed oil in your mixture. This progression secures the painting’s structure.
Practical tips for avoiding cracking in upper layers
Maintain a ratio. Less medium initially, more as you progress. Keep the paint layers thin at the start. Ensure each layer is thoroughly dry before adding the next. This strategy maintains durability and visual appeal.
Adding Dry Mediums to Enhance Texture
Techniques for incorporating sand, gravel, or beads into oil painting
Introduce dry mediums for texture. Mix sand, gravel, or beads into your paint. Use a palette knife to apply the mixture. Experiment with varying amounts for different textures.
Creative use of mixed media for added dimension
Dry mediums can enhance the tactile quality of your work. Combine different textures for complex, multi-dimensional pieces. This technique is especially effective in abstract compositions, creating a striking visual and tactile contrast.
How to apply a glaze over dry mediums for effect
Apply a glaze to unify the surface. Use varnish or a clear medium mixed with a small amount of pigment. This adds a glossy finish, highlighting the textured dry mediums beneath. The glaze enhances depth and visual interest while protecting the added elements.
Practical Application and Process
Combining Multiple Techniques in a Single Artwork
How to strategically layer techniques for a cohesive piece
Strategically layering oil painting techniques is an art in itself. Start with an underpainting to establish tonal values. Incorporate glazing for depth, scumbling for texture, and impasto for bold strokes. Each layer should complement the previous ones to form a cohesive composition.
Practical examples of using multiple methods (Alla Prima + Impasto + Scumbling)
Imagine using Alla Prima for dynamic backgrounds. Add impasto for the foreground elements, making them pop. Finish with scumbling to create atmospheric effects. An example: a landscape with Alla Prima skies, impasto trees, and scumbling mist.
Tips for blending different textures and finishes
Blend textures by transitioning smoothly from one technique to another. Use hog bristle brushes for rough textures and fan brushes for delicate blending. Control drying times to manipulate layers effectively.
Creating a Workflow for Oil Painting
The importance of planning and patience in oil painting
Planning is paramount. Sketch your composition, prepare the canvas with gesso primer, and decide on your techniques. Patience ensures each layer dries properly, preventing issues like cracking.
