Pencil lead grades

This article is intended to explain what those toryg little codes actually mean. Pencil lead is made of a mixture of graphite and clay. The graphite is the part that makes pencil lead grades dark mark on the paper.

From here, people began wrapping graphite in string and later began inserting the graphite into wooden sticks, which is how the pencil was created. Pencils are a perfect form of expression, and whether it be writing or drawing, the pencil can aid some impressive work. In this article, we will help you understand pencil lead grades and how to choose the perfect one for you and your projects. In the USA, pencil manufacturers often use a numerical scale. The scale is based on numbers, which represent the level of lead hardness in a pencil.

Pencil lead grades

The first graphite grading scale is a numeric scale. The higher the number the harder the writing core and the lighter the mark left on the paper. As the pencil core becomes softer through the use of lower proportions of clay it leaves a darker mark as it deposits more graphite material on the paper. Softer pencils will dull faster than harder leads and require more frequent sharpening. The second graphite grading scale is known as the HB scale. Most pencil manufacturers outside of the U. Today, however, most pencils using the HB system are designated by a number such as 2B, 4B or 2H to indicate the degree of hardness. For example, a 4B would be softer than a 2B and a 3H harder than an H. Generally, an HB grade about the middle of the scale is considered to be equivalent to a 2 pencil using the U. In reality however, there is no specific industry standard for the darkness of the mark to be left within the HB or any other hardness grade scale. Thus, a 2 or HB pencil from one brand will not necessarily leave the same mark as a 2 or HB pencil from another brand.

Retractable Erasers, pencil lead grades. The Tombow writes with a grippy feel. Thin leads for mechanical pencils are similar, but with a polymer or resin taking the place of the clay.

If you're new to pencils, you've probably noticed that one of the things that distinguishes one pencil from another is the letter or number printed on its barrel. It might be a 2 or a 1, or it might be a letter like H or B. Let's make sense of all of this:. The "lead" of a pencil which, by the way, has NEVER actually contained actual lead is traditionally made of three things: graphite, clay and water. These days, most pencils have a little bit of wax or other additives in them, which aid in making them smoother to write with. The "grade" or "hardness" of the pencil indicates the ratio of graphite to clay.

Mechanical pencils have fewer lead grades to choose from than wooden pencils because they have thinner lead. This guide explains the difference between mechanical pencil lead and wooden pencil lead, how mechanical pencil lead is made, the mechanical pencil lead grade scale, the darkest mechanical pencil lead, and much more. If you want to know more about colored lead for mechanical pencils, check out the Ultimate Guide to Colored Mechanical Pencil Lead for more information. The lead core of a wooden pencil is approximately 2 mm in diameter. Mechanical pencils are usually much thinner, typically 0. Because the lead is so thin, the lead is manufactured differently from that of wooden pencils, and there are fewer lead grades available. Mechanical pencil lead is fragile compared to wooden pencil lead, and it is made from different materials to make it stronger and prevent it from breaking.
