Coloured pencils can generally be categorized into three main types based on their core composition. These types include:
Wax-Based
These pencils have a core made primarily of wax and pigment. The wax provides a soft and smooth texture. These pencils are known for their vibrant colours, ease of blending, and creamy texture. They are often preferred for detailed work and artistic projects where layering and blending are crucial.
Oil-Based
Its core is made with a combination of pigments and a non-drying oil binder. Known for their lightfastness, durability, and smooth texture, they are less prone to wax bloom (a cloudy film that can develop on the pencil surface over time) and can be applied with a slightly harder pressure compared to wax-based pencils.
Water Soluble
These pencils have a water-soluble core made of a mixture of pigments, fillers, and a water-soluble binder. When applied dry, they behave like traditional coloured pencils, but when water is applied with a brush, the pigments dissolve, creating a watercolour effect. This allows for unique layering and blending techniques, making them versatile for various artistic applications.
These three types offer artists different textures, blending capabilities, and effects, allowing for a wide range of creative possibilities. The choice between wax-based, oil-based, or watercolour pencils depends on individual preferences and the specific requirements of the artwork or project.
