Gradation is a type of shading, you simply press harder and harder on the surface to forma sort of scale of shades.
The grade of pencil that is easiest to erase is typically a harder pencil, such as an H or F grade.
Yes, a 3B pencil is darker than a 2B pencil. The higher the number in the pencil grade, the softer the graphite and therefore the darker the mark it will make on paper.
You need pencil's and a binder
Use a B, 2B, or darker grade of pencil for your shading. H and 2h pencils will give you less depth.

The number "621" printed on a Nataraj pencil typically refers to the pencil's grade or hardness level. In the case of Nataraj pencils, "621" usually indicates that the pencil is of standard HB (hardness and blackness) grade, which is commonly used for general writing and drawing purposes. The number system helps users identify the pencil's specific characteristics, such as lead hardness and darkness, making it easier to choose the right tool for their needs.
Pencil lead, also known as graphite, is typically 0.2 millimeters to 1 millimeter thick, depending on the grade of the pencil. The standard size for most mechanical pencils and fine-tip mechanical pencils is 0.5 millimeters.
When writing with a pencil, you are performing a form of a hardness test rather than a streak test. The hardness of the pencil's graphite core determines how dark or light the line appears on paper, which relates to the pencil's grade (e.g., H for hard, B for black). A streak test, on the other hand, involves rubbing a mineral across a surface to observe the color of its powder, which is not applicable to writing with a pencil. Therefore, pencil writing primarily assesses the hardness of the graphite.
A pencil box is incredibly useful for students. It is particularly useful for students who study art and may own a large number of different grade pencils, as well as different colored pencils. A pencil box is also useful for students who do not study art. A pencil box helps to keeps a student's workspace neat and tidy, as well as providing a storage location for their stationary.
