Charcoal panels are specialized surfaces used primarily for drawing and sketching with charcoal. Here are some key points about them: Material: Charcoal panels can be made from various materials, including wood, MDF, or paper with a textured surface to help grip the charcoal. Texture: The texture of the panel is crucial; a rough surface allows for better adhesion of charcoal, while a smoother surface can yield finer details. Size: They come in various sizes, accommodating different styles of work, from small sketches to larger pieces. Usage: Artists often use charcoal panels for both detailed drawings and expressive, gestural work. The panels can be used with both compressed and vine charcoal. Fixatives: After completing a drawing, artists may use a fixative to prevent smudging and preserve the work. Portability: Many charcoal panels are lightweight and easy to transport, making them ideal for plein air drawing or sketching on the go.
