Pencils have never contained the metal, lead, although the word commonly used to describe the centre core of a pencil is, in English, 'lead'.
The ancient tool which preceded the modern pencil was a stylus, and these were frequently made from lead. The first versions of the modern pencil were made with graphite, a soft, carbon-based mineral, and this hasn't changed; both wooden and mechanical pencils are today made with a mixture of powdered clay, graphite and water, which is extruded into lengths and fired in ovens (kilns) until hard; the rods are then oiled or waxed for a smoother surface, preventing them catching on or damaging paper during use.
The use of graphite is ancient: evidence of pottery decorated with graphite-based compounds has been found dating back to the Neolithic Age.
The English commercialized graphite when they discovered deposits of the mineral in the 1500s; they took it to be a kind of lead and called it plumbago - from Latin, plumbum:lead - and later it became known as black lead. The marking qualities of graphite were immediately put to use by farmers in the area, for easy labeling of livestock and containers. Later, square sticks of graphite were sold for general writing; users or sellers wrapped them in various materials to protect the hands from the easily-transferred and very messy graphite residue.
Later still, the Italians began making wooden holders for graphite; their invention spread, and the term 'lead pencil'entered the English language sometime in the 1680s, the English still believing graphite was a form of, or contained some, lead.
Today we still use the term 'lead' to describe the inner core of a pencil and some still believe the core contains the metal, lead, or at least that it is in some way poisonous. It doesn't contain any lead, and it isn't at all poisonous.

Is pencil lead magnetic?
No, pencil lead (graphite) is not magnetic because it does not contain any magnetic properties. Pencil lead is made of graphite, which is a form of carbon and is not attracted to magnets.
Does a led pencil contain any lead?
No, a pencil labeled as "lead" does not actually contain the element lead. Instead, it contains graphite, which is a non-toxic form of carbon that is commonly used in pencils for writing and drawing.
What is the percentage of lead in the lead pencil you are using?
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.
Why the term lead pencil incorrect?
The term "lead pencil" is incorrect because pencils actually contain graphite, not lead. The misconception likely arose because early pencils were made with a graphite-and-wax mixture that was mistakenly believed to contain lead. Using the correct term "graphite pencil" helps avoid confusion and accurately describes the writing instrument.
Is most pencil filled with lead?
No, pencils are not filled with lead. They are filled with a mixture of graphite and clay. The "lead" in pencil terminology refers to the graphite core inside the pencil.

What is the lead made out of in a pencil?
The lead in a pencil is actually made of a mixture of graphite and clay. Despite its name, it does not contain any actual lead. The proportions of graphite and clay determine the hardness of the lead.
Does lead pencil contain lead in any form if yes what is name and formula or lead compound if there is no lead in leaded pencils why they are called so?

Which has the most lead aluminum or pencil lead?
Pencil lead isn't really lead, it is graphite, a form of carbon. Pencil lead doesn't have any lead in it whatsoever.
What elements does lead contain?
Pencil lead contains the element carbon in the form (allotrope) of graphite. The powdered graphite is mixed with a clay binder.Pencil lead has never contained any lead.
Can you get lead poision from a pencil?
No, you cannot get lead poisoning from a pencil. Pencils do not contain lead; they use graphite for the writing material. Graphite is not toxic and cannot cause lead poisoning.
