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.
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 thermal burn can be caused by exposure to heat sources such as fire, hot liquids, steam, or contact with hot objects. The severity of the burn depends on the temperature of the heat source and the duration of contact with the skin.
A burn caused by direct contact with a hot object is called a contact burn. These burns can vary in severity depending on the temperature and duration of contact with the hot object. It is important to cool the burn and seek medical attention if necessary.
Yes, calfskin parchment paper can burn as it is made from animal skin that is treated to make it heat-resistant. However, it will burn at a higher temperature than standard paper due to its nature and treatment processes.
Pencil Circuts
With fire.
The metal end of a pencil, also known as the ferrule, typically contains an eraser made of rubber. The metal ferrule can start to melt and deform at temperatures between 300-500°F (150-260°C), depending on the specific materials used. It is not designed to burn like the wooden part of a pencil.
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.
The wood in a pencil will burn in three or four minutes. The graphite inside is pure carbon which will not burn, but at around 800 degrees Celsius will react with oxygen to form carbon dioxide (CO2) and carbon monoxide (CO).
Hair will burn at 223 degrees Celsius. Hair can however burn at a much lower temperature if it is damaged.

: 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)
The "lead" in the pencil is a form of carbon called graphite. Graphite has a melting temperature of about 6606 degrees F. So, unless you can heat the graphite to that temperature, it will remain as a solid.
