The higher the number in front of the letter, the harder (H) or softer (B) the lead. When writing, drawing or shading with a pencil, the tip becomes blunted by the abrasion. No matter what you use a pencil for - for drawing or writing - a sharp lead is required at all times. That’s why you also need the right sharpener to hand.

The West Chinagraph Pencil is the original writing instrument for use on glass, acetate, film, china and other polished surfaces. The grease pencil, a wax writing tool also known as a wax pencil, china marker, or chinagraph pencil (especially in the United Kingdom), is a writing implement made of hardened colored wax and is useful for marking on hard, glossy non-porous surfaces. This pencil is usually made from non-toxic opaque wax (such as paraffin, beeswax, ceresin, carnauba or spermaceti wax) [1] that is similar to a crayon but stronger. [ citation needed] Marks made by grease pencils are resistant to moisture and can usually be removed by rubbing the marked surface with a paper towel. After mixing, we press the materials into the shape of the lead and dry them. As the lead is still very soft and bendy at this point, it has to be baked in the oven at a very high temperature. Finally, the lead is impregnated in a wax bath to make it strong and resistant to shattering.

The information would be continuously updated as the situation changed. They have largely been replaced by digital displays in the modern era.
