Pencil "lead" is actually made of graphite, which does not burn under normal conditions. The substance is used in pencils because it leaves a dark mark on paper, not because it is flammable.
A typical lead pencil does not actually contain lead. The "lead" in a pencil is made of graphite, which is a crystalline form of carbon. Therefore, there is 0% lead in a lead pencil.
A 9mm pencil lead is thicker than a 7mm pencil lead.

A pencil will start to burn at around 700°F (370°C). This is because the graphite in the pencil is flammable and will ignite when exposed to high temperatures.
No. Also, "pencil lead" is not lead; it is almost always graphite (made of carbon)
: Pencil "Lead" Is made out of Graphite and graphite is NOT flammable. However some brands of "lead" have a coating that is. If you expose a pice of "lead" to an open flame the coating will quickly burn away, the flame will extinguish, and the "lead" will remain. (still useable)

There is no lead in pencil - Pencil is made from graphite
Pencil lead is a compound
If your asking if the pencil has Lead, then the answer is that most pencils do NOT have lead in them anymore.
Pencil lead isn't really lead, it is graphite, a form of carbon. Pencil lead doesn't have any lead in it whatsoever.
we get lead of pencil from the mixture of clay and graphite
Pencil lead is a conductor.
A 9mm pencil lead is thicker than a 7mm pencil lead.
Pencil lead is made of graphite and clay. Newer recipes for pencil lead use waxy polymers to bind the graphite to produce a lead that does not snap when the pencil is flexed.
With fire.
