An art sanding block, also known as a sandpaper block or pad, is a useful tool for artists working with pencils and other dry media. Its primary function is to provide a coarse surface for shaping tips and cleaning tools.
What is an Art Sanding Block Used For?
Based on the provided reference, a key use for an art sanding block is to sharpen the tips of drawing pencils when they become blunt, even if there is still plenty of color left. This method allows you to refine the pencil tip without sharpening down the entire pencil using a traditional sharpener, thus preserving more of the pencil material.
- Sharpening Pencil Tips: Instead of constantly using a blade or a sharpener which removes layers of the pencil, you can gently rub the blunt tip on the abrasive surface of the sanding block to quickly create a fine point again. This is particularly useful for colored pencils or graphite pencils where you only need to reshape the tip for detail work.
- Cleaning Blending Tools: Sanding blocks are also commonly used to clean tools like paper stumps (tortillons) or blenders that have accumulated pigment from blending. Rubbing the dirty tip of the stump on the sandpaper removes the pigment, allowing you to use it again with different colors.
- Creating Pigment Dust: Artists may also use the sandpaper to grind pigment off pencils or pastels into a powder form, which can then be applied with brushes or blending tools.
Step-by-Step Guide to Using a Sanding Block for Pencils
Using an art sanding block to sharpen a pencil tip is straightforward:
- Identify a Blunt Tip: Notice when your pencil tip becomes blunt but still has a good amount of lead or pigment remaining.
- Access the Sandpaper: Hold the sanding block firmly.
- Rub the Tip: Gently rub the very tip of the blunt pencil back and forth or in a circular motion on the abrasive surface of the sandpaper.
- Check the Point: Continuously check the pencil tip until you achieve the desired point sharpness.
- Clean Up: Excess graphite or pigment dust will collect on the sandpaper or surface below. Be mindful to clean this away carefully to avoid smudging your artwork. Sanding blocks often have multiple sheets of sandpaper, allowing you to tear off a used, dirty sheet to reveal a fresh one underneath.
