Virtually all graphite used today is a manufactured mixture of natural graphite and chemicals.

The Surprising History of the Pencil The thickness of graphite left on a sheet of paper by a soft 2B pencil is about 20 nanometers and a carbon atom has a diameter of 0.14 nanometers, so the pencil line is only about 143 atoms thick. The pencil lead is about 1 mm in radius and therefore ? square mm in area.

Build a Better Pencil K-2 students should be given many opportunities to design and make things using a variety of materials and simple tools. This investigation uses a pencil to introduce the idea of planning and evaluating designs. The familiarity of this object will allow students to propose a variety of ideas on how to improve it. The small scale of this design challenge allows for a greater range of solutions that can be carried out using everyday classroom tools and materials.

A Brief History of the Mechanical Pencil Despite what David Rees claims in Chapter 11 of How to Sharpen Pencils, mechanical pencils do have their place in the pencilverse. Surprisingly, this wonder of pencil technology has actually existed in one form or another for the better part of five centuries. If you take a look at pencil history, you will see that the first image of a pencil ever produced actually looks more like modern mechanical pencils than a wooden pencil. This 1567 image depicts a wooden stock that held replaceable graphite.

The higher the number, the darker you can go.6B is much darker than 2B. If you want a really light line use an H pencil.. Using small, fine lines with a pencil, quickly and lightly sketch the basic form of the object you are trying to draw. Try to break it down to basic shapes or forms.

- Today pencils are numbered and/or lettered to tell us how hard the lead is. The higher the number, the harder the lead, and the lighter the markings. However, it wasn't always this way. The earliest pencils were made simply from filling a wood shaft with raw graphite. The hardness of the graphite would differ depending on the quality of the graphite, thus it was different depending on where the pencil was made. The current style of making pencils was developed in 1794 by Nicolas-Jacques Cont (1755-1805).

The pencil hadn't taken on it's true form until 1660 when they were made as graphite rods encased with wood as we know them today. The only main difference is in the graphite mixture.
