What makes pencil lead hard?
The graphite used in pencils is quite soft. Clay is added to the graphite to strengthen the 'lead' of the pencil. The amount of clay used changes the pencil's rating, with HB being the commonest, B2 being softer (darker marks), and H being harder (lighter marks).
What is the lead part of a pencil made of?
first step in pencil manufacture involves making the graphite core as the "lead". Back in the day we used lead which is toxic, the we switched to Graphite which is non-toxic. --------- It is frequently called "lead" as in "lead" pencils. But there is no lead in Graphite. Pencils simply contain a mixture of graphite and fine clay in varying proportions to make them hard or soft.
Is pencil lead a compound or an element or an homogeneous mixture or a heterogeneous mixture?
Pencil lead is actually not lead (Pb) at all, but it is graphite. And graphite is simply carbons atoms. So, no, it is NOT a compound mixture.
How has the pencil changed?
Although rumors suggest that pencils used to be made from pure lead, this is a myth. Pencils have always been made of graphite since the mineral's discovery in 1565. The pencil hadn't taken on it's true "form" until 1660 when they were made as graphite rods encased with wood as we know them today. The only main difference is in the graphite mixture. Today our pencils are made with a mixture of graphite and clay to create dark marks such as those of number two pencils or HB (hard, bold) marks.
What dos hb stand for on the pencil?

Why can pencil lead can be used to make a light bulb?
A "pencil lead" is a mixture of the graphite allotrope of carbon mixed with clay and baked hard. While a pencil lead will conduct electricity, it can not be used to make a light bulb.
Why do pencil stabs leave a lasting mark on surfaces?
Pencil stabs leave a lasting mark on surfaces because the graphite in the pencil tip is hard and can scratch or indent the surface, leaving a visible mark that is difficult to remove.
