The higher the number the harder the writing core and the lighter the mark left on the paper. As the pencil core becomes softer through the use of lower proportions of clay it leaves a darker mark as it deposits more graphite material on the paper. Softer pencils will dull faster than harder leads and require more frequent sharpening.
The second graphite grading scale is known as the HB scale. Marks can be subtle and delicate or bold and vigorous. A few bold strokes can capture movement whilst tonal shading can define form. A great characteristic of pencil is that line and tone can be combined in one drawing.
When executing a line drawing, the look of a line depends on several factors. These are the grade of the graphite used, its sharpness, the pressure applied, the speed with which the line was drawn and the texture of the paper.
There are no rules governing this — it all depends on your style of drawing, the subject matter or atmosphere that you are seeking to create. Tones can be achieved in a number of ways. The classic technique goes back to the time of Silverpoint and involves drawing closely juxtaposed lines that become lighter and fainter as they move out of shadowed areas into lighter ones. Other methods used to express tone include cross-hatching — two layers of crossing lines — dots and smudging the graphite with fingers, stumps or rubbers.
Interesting tonal areas can also be achieved by rubbing the pencil over paper that has been laid on a textured surface. For detailed drawings, erasers can lift any errors. For sketching, however, rough lines and random marks can add to the piece and so rubbers should not be over used. Next time you need to do some deep shading , you'll know exactly which pencil is your darkest. Need to make light cross-hatching marks? Just grab the perfect H pencil for the job. This simple, five-minute task can take the guesswork out of drawing.

This type of pencil should also be used when you are looking to create moderately dark blacks that blend.
But, that same softness that lets them smudge easily also makes them great for blending. Using a 5B pencil will let you add dark values that are getting close to the darkest values that graphite can produce.
Getting graphite to create pure black is difficult because of the sheen that it has. But, with the right pencils and sufficient pressure, you can get close to creating black. It is the pencil you should use when you are trying to add dark shadows and blend them between lighter areas and darker areas on your drawing. They will allow you to create reasonably dark areas, are easy to blend, and are soft enough that you can lay down a lot of graphite quickly.
Like other soft, dark pencils, you should use a 6B to help bridge the gap between lighter and darker values in your drawing. Once you get to the 7B range of pencils, you are getting into pencils that are quite soft, blend easily, and can make very dark values.
If you are drawing a dark scene , then using an 8B pencil along with an eraser to lighten areas that are lighter in value. When you are ready to create the darkest values that graphite is capable of producing, then you are prepared for a 9B pencil. They smear and blend easily, and you can put down a lot of graphite with a minimal amount of pressure.
This makes a 9B pencil great for laying down dark shadowy areas. Many young artists struggle with creating the darkest black areas in their drawings. This is a mental hurdle that has to be overcome because, without truly dark regions, a picture will always look flat. As an artist, creating the illusion of three-dimensional depth, while drawing on a two-dimensional surface, requires practice and skill. It also requires a full range of values.
Take a moment to look around the room around you. What do you see? No, you see a full range of different values ranging from a slight shadow to an area nearly devoid of light. What about highlights? Are all of the highlight pure, bright white? They are also comprised of a range of values. How many values? Believe it or not, you should be drawing using 9 different values.
One of the best ways to practice this and get a feel for different values is to create a tonal scale. How do you do that? Choose a sheet of paper. While any paper will do in a pinch, using a smoother paper will give you more precise control as you add graphite to create values. Get several different pencils ready. Draw out 9 different squares. These squares can be drawn by hand and messy, or if you are a perfectionist, you can use a ruler and at-square to draw perfect squares.
Starting with number 2, you are going to start adding graphite to each square to make each square. For many people, it helps to do a value scale in stages. Leave box 1 blank for the lightest value. In box 9, use a 9B pencil to create as dark of an area as possible. In box 5, you are going to want to use something like a 5B pencil.
