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.
The lead in pencils are not made out of lead, as is common belief. Pencil lead is made out of graphite.
Pencils are no longer made with lead. They are made with a mixture of graphite and clay. This combination produces the "lead" in modern pencils.
both, lead is made of graphite.
No, pencils are not made out of lead. They are made from a combination of graphite and clay. Lead was used in early pencils, but its toxic nature led to the transition to graphite.
Yes. It is graphite
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.
Zero, pencils are made with graphite not lead.
It is called "lead" because the original pencils were made from soft lead. However lead is a toxic heavy metal.Modern pencil "lead" is made of graphite and a binder. The most common binders are clay or plastic resin. This is completely nontoxic and the hardness can be precisely controlled to meet the requirements of different users.
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.
When the graphite deposit that produced the first pencils was discovered, the people thought it was lead. Later, chemists told them it was graphite, a form of carbon, but the 'lead pencil' had already become so popular that the name persists to this day.
Lead pencils do not actually contain lead; they are made of graphite. Graphite is not toxic to humans, so there is no risk of lead poisoning from using pencils. However, ingesting graphite or pencil fragments can cause mechanical irritation in the digestive tract.
'Lead' pencils never contained any lead. They are made of a mixture of graphite and clay.
