Coloured pencils, are a versatile and accessible medium for artists. Among the various types available, two popular variants are oil-based and wax-based coloured pencils. Each possesses unique characteristics and applications that make them well-suited for specific artistic endeavours. In this essay, we will delve into the differences between these two types of coloured pencils and explore the factors that influence the choice between them.
Defining Oil-based and Wax-based Coloured Pencils:
Oil-based coloured pencils are formulated with a binder that primarily consists of oil, while wax-based coloured pencils employ a binder composed mainly of wax. This distinction influences the behaviour, texture, and overall performance of the pencils on different surfaces.
- Composition and Texture:
- Oil-based coloured pencils utilise an oil-based binder, which provides a creamy and smooth texture. This characteristic allows for effortless blending and layering, making them particularly suitable for creating gradients and achieving a smooth finish. On the other hand, wax-based coloured pencils have a wax-based binder, resulting in a harder texture that produces distinct, crisp lines. Wax-based pencils are ideal for intricate detailing and precise rendering.
- Colour Intensity and Translucency:
- The binder composition of coloured pencils affects the intensity and translucency of the colours they produce. Oil-based coloured pencils generally exhibit richer and more vibrant hues, as the oil binder helps pigments adhere more effectively to the drawing surface. In contrast, wax-based coloured pencils may appear slightly less intense but offer greater translucency, allowing underlying layers to show through. This quality can be advantageous for creating luminous effects and delicate glazes.
- Blending and Layering:
- One of the key considerations when choosing coloured pencils is their blending and layering capabilities. Oil-based pencils, owing to their soft and buttery consistency, blend effortlessly, enabling artists to create smooth transitions and gradients. Layering multiple colours is also relatively easy, as the oil binder allows subsequent layers to adhere and interact smoothly. Conversely, wax-based pencils may require more effort to blend due to their harder texture. However, they are excellent for layering, as the wax binder enables colours to build up without smudging or muddying.
- Surface Compatibility:
- The choice of coloured pencil type can also be influenced by the desired drawing surface. Oil-based coloured pencils are highly versatile and work well on a variety of surfaces, including paper, canvas, and even wood. Their creamy texture allows for smooth application on different mediums. Wax-based coloured pencils, with their harder lead, are particularly suited for paper-based projects, where their precise lines and controlled application can enhance the overall detail and realism of the artwork.
- Longevity and Preservation:
- The durability and longevity of coloured pencil artworks depend on several factors, including the stability of the binder used. Oil-based coloured pencils, with their oil binder, tend to have excellent lightfastness, meaning the colours will resist fading over time. This makes them a preferred choice for artists seeking long-lasting and archival-quality works. Wax-based coloured pencils, while generally offering good lightfastness, may require additional precautions or protective measures to ensure their longevity.
Conclusion:
Oil-based and wax-based coloured pencils are distinct mediums that cater to different artistic needs. Oil-based pencils are characterised by their soft, creamy texture, vibrant colours, and excellent blending capabilities, making them suitable for creating gradients and smooth finishes. Wax-based pencils, with their harder texture and precise application, excel in detailed work and offer greater translucency for layered effects. Understanding the characteristics, application, and surface compatibility of each type can help artists make informed choices based on their artistic vision and desired outcomes. Ultimately, the selection between oil-based and wax-based coloured pencils depends on the artist’s preference, style, and the specific requirements of the artwork at hand.
