Types and Usage
A pencil, sometimes called a lead pencil, a black-lead pencil, is a writing implement or art medium constructed of a narrow, solid pigment core inside a protective casing which prevents the core from being broken and/or from leaving marks on the user’s hand during use.
There are mainly 2 types of Pencils.
1. Lead Pencil: The most common type of pencil casing is of thin wood, usually hexagonal in section but sometimes cylindrical, permanently bonded to the core. Similar permanent casings may be constructed of other materials such as plastic or paper. To use the pencil, the casing must be carved or peeled off to expose the working end of the core as a sharp point.
2. Mechanical pencil: Mechanical pencils have more elaborate casings which are not permanently bonded to the core. Instead, the casing supports a separate, mobile piece of pigment core that can be extended or retracted through the casing tip as needed; these pencil casings can be re-loaded with a new core (usually graphite) when necessary.
Other types of pencils include:
Blue pencil (editing), Carbon pencils, Carpenter’s pencils, Charcoal pencils, Colored pencil, Copying pencils, Eyeliner pencils, Golf pencils, Graphite pencils, Graded pencils, Grease pencil, Indelible pencils, Library pencils, Liquid graphite pencils, Non-photo blue (pencil), Non-repro blue, Non-reproducing pencil, Pencil crayon, Shorthand pencils, Solid graphite pencils, Stenographer’s pencils, Watercolour pencils, Wax pencil.
What is the way to use different kinds of pencils, such as 1h to 9b?
Pencils are like a number line, from 9B to 9H. B means soft, H means hard; the higher the number the harder/softer the pencil is. Use H pencils when you want lighter lines/shading, use B when you want darker lines/shading.
Pencils have a variety of uses– for arts, for pointing at things, and for poking and prodding where fingers simply shouldn’t go.
