An F graphite pencil has a soft lead which has been shaped into a pencil head. The lead is formed by heating a graphite powder using an electrically heating rod which is usually made of lead. The graphite powder will begin to turn to graphite when heated to between about 400 °C and 660 °C. When the graphite powder is heated at about 600 °C, all the graphite will solidify. The graphite which does not solidify will give the pencil its “focal point.”
F graphite pencils usually give an elongated “point,” or “bracket,” which has a very small area of surface area and is usually about 1.5 mm diameter. F graphite pencils also contain lead, which provides resistance but less durability than graphite. As an example, a 1.5 mm diameter lead pencil will last longer than an F graphite pencil which has a 1 mm diameter lead pencil, but it will not give as well with a larger lead pencil as the F pencil.
How many F graphite pencils are there in a box?
F graphite pencils come in a variety of different sizes and weights and can be grouped by brand name. One common size for F graphite pencils are the B-Series (12, 18, 24 and 32 mm diameter) since they require relatively little lead. B-Series have an ideal paper quality of .010– .030 mm, while the B-Series has a paper that has a smooth feel with a soft and textured surface to it, which is known as “lead”.
What is a nib?
A nib is a small, flexible plastic device attached to a pencil. A nib enables the user to choose the pencil type. Most pencil makers have a range of nib sizes for different writing techniques. Nib type can be a big part of the appeal of a pencil, especially for novice writers. NIB is not the same as nib size, only that the nib size determines what writing experience the person will have with the pencil. An F pencil will typically come with a small nib on a larger lead writing instrument, while a B-Series pencil will come with nib sizes on the B-Series.
