No. This is totally untrue. There is no lead in pencils - not even in the paint they are painted with! The reason for this is caused by confusion over the name of the filler. The substance inside a pencil that does the actual writing is called graphite. This is a crystalline form of carbon (another is diamond, another is a substance called buckminsterfullerene, and the third, non-crystalline form, is charcoal). The graphite is often mixed with differing amounts of clay to create pencils of different hardnesses. Graphite is found as a mineral in the ground. Lead is also found as a mineral in the ground as the lead ore 'lead sulphide' or 'Galena'. The mineral Galena looks very similar to graphite, except that graphite is darker in colour than lead ore. Therefore, many years ago graphite used to be called 'black lead' from its appearance. So, when pencils were invented, they were filled with graphite - or 'black lead', and eventually this was shortened to 'lead' but there is absolutely no connection with the 'lead' (i.e. black lead) found in pencils with the metal lead. The "lead" in pencils was always, is, and always will be, made of graphite.
What else can I help you with?
Is most pencil filled with lead?
Some pencil's are filled with lead, but rarely any nowadays. Pencils use to be filled with lead, but now pencils are typically filled with graphite as lead is poisonous to humans.
What do we use for lead in pencils?
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.
How thick is pencil lead?
Pencil lead, also known as graphite, is typically 0.2 millimeters to 1 millimeter thick, depending on the grade of the pencil. The standard size for most mechanical pencils and fine-tip mechanical pencils is 0.5 millimeters.
What are three substances from most dense to least dense?
In general terms, osmium is the most dense element, followed by iridium, and then platinum.
Which material is used in pencils?
Graphite is the most common material used in pencils. It is a form of carbon that allows for smooth writing and drawing. The hardness of the graphite determines the darkness of the mark made by the pencil.
What is the full process in steps of making lead used in pencils?
1. Find lead 2. Put in pencil Btw most pencils use graphite
What year did they take the lead out pencils?
The United States began phasing out lead in pencils in the late 19th century, with significant changes occurring in the 1970s. The term "lead" in pencils actually refers to a mixture of graphite and clay, not actual lead. However, concerns about lead poisoning led to the regulation of lead in various products, including pencils, leading to the widespread use of safer materials. By the 1970s, most pencils were already free from harmful lead content.
What element is present in lead graphite?
Graphite is a form of Carbon, so its carbon in lead graphite. Notice that lead itself is a different element but the term "lead graphite" is generally used for that black substance which makes the "lead pencils". Note that there is no lead in lead pencils, its carbon, in the shape of graphite.
Is most pencil filled with lead?
Some pencil's are filled with lead, but rarely any nowadays. Pencils use to be filled with lead, but now pencils are typically filled with graphite as lead is poisonous to humans.
What elements found in pencil?
Modern pencil "lead" is made from the element Carbon (C) - in its soft form of graphite - plus a filler (like clay), all ground up very fine and then stuck together with glue. It has none of the actual chemical element Lead (Pb).Further informationThe name "lead" is used because, before modern pencils were invented, it was known that a pure piece of the element Lead (Pb) can be used to make marks on wood or paper because it is very soft. It is not used today because real Lead and its compounds are poisonous and also very expensive compared to Carbon. (Carbon is basically soot.)

When did they stop using lead in pencils?
Pencils were never made with lead, they have always been made with graphite. When pencils were first made it was beleived that graphite was a type of lead, but science has now proven graphite is a type of carbon, not lead. Well, i didn't want to delete this person's answer, but it is wrong. In fact, lead was used in pencils for hundreds of years, but there was a major problem with using lead. These pencils would form lead oxide on the tips, making it difficult to write, so when people wanted to write, they would lick the lead of the pencil to get the lead oxide off. When people realized that this was dangerous because consuming lead (even in minute quantities) can cause brain damage, pencils began to be manufactured with graphite instead of lead. Coming back to your original question - I don't know when they switched to graphite, but I think that it was sometime in the first half of the 20th century.
Do mecanical pencils have lead in them?
No, they have graphite. Soon after people realized that lead is very toxic and poisonous, they removed it from most writing devices and such.
Is a pencil poison?
If your asking if the pencil has Lead, then the answer is that most pencils do NOT have lead in them anymore.
What are major uses of lead?
usually lead can be found in most graphite pencils as well as childrens toys if you know about the possibility of lead poisining in china. as well as cable wires and most technology. XD
Which element is most often found in charcoal and pencil points?
Carbon is the element most often found in charcoal and pencil points. It is the main component that gives charcoal and graphite pencils their dark color and ability to create marks.
Is pencil lead a conductor?
Yes, pencil lead is a conductor of electricity. Lead is a metal. Most metals are good conductors of heat and electricity. Assuming of course you mean pencils back when lead was actually used as the writing medium in the pencil, then yes. Other than that, pencils nowadays are made using graphite as the writing medium. But graphite too can conduct electricity.
