Applying shading techniques to geometric forms

Although most of us have heard someone refer to the material within a graphite pencil as "lead", you may be surprised to learn that there isn't any lead there at all. Instead, graphite is a form of carbon and is completely safe for drawing.

Graphite is produced in various grades or degrees according to the softness or hardness of the material. Different grades produce different types of marks. The grade of the pencil is usually designated on the side or the end of the pencil. For drawing pencils, this designation is an alphanumeric value. Writing pencils differ in how they are categorized and usually only feature a number. For example, a #2 pencil is a standard writing pencil - which happens to be of the same softness as an "HB" drawing pencil.

Grades of drawing pencils are organized in a scale based on softness or hardness. An "HB" pencil is found directly in the center of the scale.

"H" pencils feature harder graphite. (The "H" stands for "hard".) "B" pencils feature softer graphite. (The "B" stands for "black".)

The number found in front of the letter reveals just how soft or hard the pencil is. In other words, a "4H" pencil is harder than a "2H" pencil while a "4B" pencil is softer than a "2B" pencil.

Harder pencils produce lighter marks since less of the material is released as pressure is applied. Softer pencils make darker marks since more of the material is released. Therefore, a "4H" pencil will produce lighter marks than an "2H" pencil while a "4B" pencil will make darker marks than a "2B" pencil.

The "F" pencil is similar in mark to an "HB" pencil, only slightly lighter. Like an "HB" pencil, it is capable of producing darker and lighter marks, but without any extremes. The graphite material found in an "F" pencil is slightly harder than an "HB" pencil meaning that it can stay sharp for a longer period of use. For this reason, this pencil is designated as "fine" which is why this pencil is labeled with an "F".
