What is graphite? - Graphite is one of crystalline's that are formed from carbon.
The second one is diamond.
What is an HB pencil? - An HB pencil is a standard pencil, equivalent to a #2 pencil.
HB is an option on the HB scale.The HB scale represents how hard (H) or soft (B) a pencil is. The HB is the option in the middle, with other softer (to the left) and darker (to the right) shades surrounding it. The farther to the left on the scale, the lighter the pencil will be, vice versa. Most manufactures outside of the U.S. use this scale.
What happens when the H# is increased? - When the H is increased, the pencil will be harder.
The more H, the harder and blacker the pencil will be. You could google a picture of an HB scale to see an example.

Pencil drawing is a type of drawing in which the artist uses a graphite-based instrument housed in a wooden shell to create a sketch for a more extensive work in another media, an exercise in visual expression, or a finished work.
1) In 1795, pencils were first used.
They were created by Jacques Conte, a physicist who had previously served in Napoleon Bonaparte's army.
2) Graphite is one of the carbon-based crystalline materials.
Diamond is the second option.
3)A standard pencil, corresponding to a #2 pencil, is known as an HB pencil.
On the HB scale, HB is an option.
The HB scale indicates whether a pencil is firm (H) or soft (B). The HB choice is in the center, surrounded by softer (to the left) and darker (to the right) hues.
The lighter the pencil is, the farther to the left on the scale it is, and vice versa. This scale is used by the majority of manufacturers outside of the United States.
4) The pencil will become tougher as the H is increased.
The harder and blacker the pencil is, the more H it has. To view an example, look for an image of an HB scale on the internet.
