oil painting

Oil painting, a distinguished and versatile art form, originates in the 7th century in Afghanistan. Its significance burgeoned during the 15th-century European Renaissance, overtaking egg tempera.

Critical materials include pigments mixed with drying oils like linseed oil and various brushes for different techniques.

Artists typically choose between stretched canvas, canvas panels, or boards, with linen and cotton canvases offering distinct textures.

Thinning and layering methods facilitate depth and stability, including ‘fat over lean,’ glazing, and impasto.

These techniques and material choices profoundly influence the artwork’s outcome and longevity. Exploring these elements reveals the nuanced complexities of oil painting.



Brief Overview

  • Oil paints from pigments and drying oils create vibrant and durable artworks.
  • The ‘fat over lean’ rule ensures proper layering and prevents cracking in oil paintings.
  • Essential tools include brushes and surfaces like stretched canvas or canvas panels.
  • Techniques like glazing, scumbling, and impasto add depth, texture, and dimension to paintings.

History of Original Oil Painting

The evolution of oil painting reflects the development of artistic techniques and materials.

Its roots go back to the 7th century AD in Afghanistan and gained prominence in Europe through the innovative practices of Early Netherlandish painters in the 15th century.

Initially used in Europe for statues and woodwork by the 12th century, oil painting became a dominant medium during the Renaissance, marking a significant shift from egg tempera.

This change heralded a new era of artistic expression characterised by depth, realism, and intricate details.

The adoption of canvas over wooden panels in the late 15th century further expanded the possibilities, enabling artists to explore new styles and techniques, ultimately shaping the trajectory of Western art.



Essential Materials

A thorough understanding of essential materials in oil painting is crucial for achieving technical excellence and artistic expression. Key materials include:

  1. Oil Paints: High-quality paints from pigments and drying oils guarantee vibrant and durable artwork.
  2. Brushes: Various brushes such as filbert, flat, and round are essential for different techniques and details.
  3. Painting Surface: Options like stretched canvas, canvas panels, or boards provide a sturdy base.
  4. Oil Mediums: Linseed, walnut, or safflower oil thin paints extend drying time and create varied effects.

Each component dramatically influences the outcome and longevity of a painting, underscoring the necessity for artists to select and utilise these materials meticulously.



Painting on Canvas; Selection

Choosing the appropriate canvas is foundational to the success and durability of an oil painting.

You must make an informed decision between options such as stretched canvas, canvas board, and canvas panel.

Linen canvases, noted for their tighter weave, provide a smooth, refined surface, whereas cotton canvases offer a coarser texture with more pronounced teeth.

Pre-stretched and pre-primed canvases are advantageous for beginners, offering convenience and immediate usability.

Canvas keys may tighten slack surfaces, ensuring a taut and even painting ground.

The processes of sizing and priming are critical; sizing seals the canvas fibres, preventing oil absorption, while priming establishes a stable base for paint adherence, enhancing the artwork’s longevity and visual appeal.




Some serious oil painters believe it’s better to work on a canvas prepared with an oil-based primer rather than an acrylic one, and they prefer to buy ‘oil-primed’ linen canvases, even though these can be more expensive.

However, many painters are perfectly content with a universally-primed canvas. Some may add an extra coat of primer if they feel the priming layer is too thin, the canvas lacks tautness, or it is too absorbent.



Thinning Techniques

Mastering thinning techniques in oil painting is crucial for achieving the desired consistency, flow, and transparency, greatly influencing the artwork’s outcome. Thinning oil paint involves understanding various solvents and oils to create the perfect mix.

Here are key considerations:

  1. Solvents: Use white or mineral spirits to thin paint for initial layers.
  2. Oil Ratios: Balance oil and solvent ratios to control paint flow and transparency, making each layer of paint interact harmoniously.
  3. ‘Fat over lean’ Rule: Apply this rule to guarantee proper layering, preventing cracking.
  4. Oil Types: Experiment with linseed, safflower, walnut, and poppy oils for different effects.

These techniques allow artists to manipulate the medium, adding depth and dimension to their work.



Layering Methods

Building on the understanding of thinning techniques, layering methods in oil painting involve strategically applying multiple layers to enhance depth, texture, and visual complexity.

This process adheres to the ‘Fat over lean’ rule, where thicker, oil-rich layers are applied over thinner, lean ones to guarantee proper drying and structural stability.

Techniques such as glazing, scumbling, and impasto are integral to layering, each contributing distinct visual effects.

Glazes add translucent colour, scumbles provide a broken, textured surface, and impastos offer bold, three-dimensional strokes.

Through these methods, artists can gradually build up colours, highlights, shadows, and intricate details, resulting in a rich visual impact and dimensionality of painting.



Brush and Tool Selection

The selection of brushes and tools is crucial in oil painting, as it directly influences the artwork’s application, texture, and overall aesthetic. Professional artists often choose specific brushes and tools to achieve desired effects.

Common choices include:

  1. Brushes with hog hair or synthetic bristles: Ideal for traditional techniques, providing control and durability.
  2. Palette knives and silicone painting tools are versatile for mixing and applying paint, allowing varied textures.
  3. Brush shapes like filbert: Essential for creating specific effects, from broad strokes to fine details.
  4. Unconventional tools such as rags, sponges, and cotton swabs help addunique textures and experimental elements.

Experimenting with various tools can significantly enhance the artist’s ability to create diverse and dynamic compositions in oil painting.



Colour Mixing

Having equipped oneself with the appropriate brushes and tools, the next critical aspect of oil painting to address is the art of colour mixing.

Colour mixing in oil painting necessitates a profound understanding of colour theory and using a colour wheel to blend primary, secondary, and tertiary colours. Mastery of this skill allows artists to achieve a harmonious balance between warm and cool tones, such as blending reds with blues to create purples or mixing yellows with blues to yield greens, thereby enhancing the tonal quality of the artwork.



Varnishing Tips

Achieving the best possible preservation and presentation of an oil painting necessitates a meticulous approach to varnishing, which is the pivotal final step in the artistic process.

Varnishing protects the artwork from dust, dirt, and UV damage and enhances its visual appeal.

To guarantee excellent results, consider the following tips:

  1. Timing: Varnish only after the painting is fully dry, typically 3-12 months post-completion.
  2. Type of Varnish: Choose matte, satin, or glossy finishes based on aesthetic preference.
  3. Application Method: Use traditional varnishes like dammar gum dissolved in turpentine for a classic finish.
  4. Environmental Conditions: To avoid imperfections, apply varnish in a dust-free environment.

These guidelines assist in safeguarding and showcasing your oil paintings effectively.



Brief History

The earliest known surviving oil paintings are Buddhist murals from around 650 AD in Bamiyan, Afghanistan, a historic Silk Road settlement famous for the Bamiyan Buddhas.

These murals, found in rooms behind the statues, use a variety of pigments and include a final varnish layer. 

The refinement and survival of these works suggest oil paints were used in Asia before the 7th century.

Europeans later advanced the technique, beginning with Early Netherlandish painting. By the Renaissance, oil painting had largely replaced tempera in Europe.
