the lead in a lead pencil is made from clay and graphite
The lead in pencils are not made out of lead, as is common belief. Pencil lead is made out of graphite.
both, lead is made of graphite.
The lead inside the pencil is made from Graphite which is a natural form of carbon. The heavy metal Lead has never been used in pencils since its invention. If lead have been used instead of graphite the users of pencils may not be alive because lead and its compounds are very toxic.
No, 0.5 mm lead won't work with 0.7 mm pencils.
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.

Yes. It is graphite
Zero, pencils are made with graphite not lead.
Pencils were made of lead but it changed to graphite because they new the dangers of lead. 1564 was the time the United States switched to graphite
'Lead' pencils never contained any lead. They are made of a mixture of graphite and clay.
No, they are made out graphite and clay. the only reason why they are called "lead" pencils is simply because way back in ancient greek times, they once used lead as a writing utencial. But after used a few times they quickly stopped the use of lead in pencils.
The English word "Lead" seems to be a mistaken description for lead. Since lead can be used to write, pencils made with graphite were also called "lead pencils". The chemical symbol for Lead is Pb which is from the Latin word plumbum.
because it is not lead it is either graphite or a type of charcoal.
Lead has never been used in lead pencils. The lead in a lead pencil is made of graphite, a form of carbon, together with clay and other additives that hold it together. Owing to a poor understanding of science, the graphite deposit that produced the first pencils was originally thought to be lead. The term is still used to refer to the core of pencils.
No, the lead in a pencil does not contain lead. Lead that is in pencils are made out of graphite.
Pencils have never been made from lead. They are made with Graphite, a form of carbon. So you can not get lead poisoning from a pencil.
