Is a lead pencil really made with lead?
There is absolutely no trace of lead in the lead pencil; as its marking element is made out of graphite, which is one of the natural forms of carbon. The name lead pencil for a pencil is misnomer. As Romans happened to use a writing device called “stylus” in ancient times, which would write on wax surfaces using stylus, a pen-like writing device made of lead.
What is used to make pencil lead?
Let’s have a brief look at the procedure:
- The first step involves grinding the graphite and clay in a huge metal drum, which contains rocks.
- Then upon pulverization, a fine powder of graphite and clay becomes when the drum is rotated.
- Water is added in regulated quantities, and the mixture is left to blend for at least 72 hours.
Is the lead in the pencil really lead?
True or false: You can get lead poisoning if you’re stuck with a lead pencil. False. Lead pencils contain graphite (a form of carbon), not lead. In fact, contrary to what many people believe, lead pencils never were made with lead. The ancient Romans used a writing device called a stylus.
Is lead still used to make pencils?
“Is lead still used to make pencils?” This question is based on a false premise: lead (the metal) was never used to produce leads (pencil cores). The name comes from the fact that when natural graphite deposits were discovered, it was (incorrectly) believed that it was a type of lead ore. Graphite is a form of carbon.
Is an F pencil lighter than an H?
An F pencil is not lighter than an H pencil. The F pencil is one step beneath the H pencil on the blackness scale. On the numeric scale, H is referred to as number 3, HB is number 2 and since F is in between these two it is considered number 2.5.
What is F type pencil?
The "F" pencil is similar in mark to an "HB" pencil, only slightly lighter. Like an "HB" pencil, it is capable of producing darker and lighter marks, but without any extremes. The graphite material found in an "F" pencil is slightly harder than an "HB" pencil meaning that it can stay sharp for a longer period of use.
What is F lead used for?
The letter “H” is used to indicate the hardness of a pencil's mark. The letter “B” is used to indicate the blackness of a pencil's mark (a darker mark means a softer lead). The letter “F” is used to indicate that the pencil lead is a special formulation that will maintain a fine point.
What is F shade?
F means Fine Point. This is quite a hard pencil and is easy to keep sharp, but generally a bit too hard for general drawing. The more H's, the harder a pencil is. This means that a 4H pencil is harder than a 2H and therefore also lighter.

What is the darkest pencil lead?
B9 is the softest and darkest. 9H is the lightest and hardest graphite pencil. So a B6 is softer and darker than a B2. An 6H is harder and lighter than a 2H and much harder and lighter than a HB or a B pencil.
What is the softest pencil lead?
The Numbers Softer lead gets a B grading, with a number to say how soft the lead is. B on its own is just a little softer than HB. 2B, 3B and 4B are increasingly soft. Further up the range, 9B is the very softest lead available, but so soft and crumbly that it's rarely used.

And that, my friends, is how the number 2 lead pencil came to be.
