  • A pencil is an implement for writing or drawing, constructed of a narrow, solid pigment core in a protective casing that prevents the core from being broken or marking the user's hand.
    The lead of the pencil is a mix of finely ground graphite and clay powders. Before the two substances are mixed, they are separately cleaned of foreign matter and dried in a manner that creates large square cakes. Once the cakes have fully dried, the graphite and the clay squares are mixed together using water. The amount of clay content added to the graphite depends on the intended pencil hardness (lower proportions of clay makes the core softer), and the amount of time spent on grinding the mixture determines the quality of the lead. The mixture is then shaped into long spaghetti-like strings, straightened, dried, cut, and then tempered in a kiln. The resulting strings are dipped in oil or molten wax, which seeps into the tiny holes of the material and allows for the smooth writing ability of the pencil.
    A juniper or incense-cedar plank with several long parallel grooves is cut to fashion a "slat," and the graphite/clay strings are inserted into the grooves. Another grooved plank is glued on top, and the whole assembly is then cut into individual pencils, which are then varnished or painted. Many pencils feature an eraser on the top and so the process is usually still considered incomplete at this point. Each pencil has a shoulder cut on one end of the pencil to allow for a metal ferrule to be secured onto the wood. A rubber plug is then inserted into the ferrule for a functioning eraser on the end of the pencil.

      Yeah even if the dust is non toxic, which I don't know, it's still way too much particle dust in your lungs every day to be heslthy. A mask is cheap.

    The sharpening was the most amazing part of the process in my opinion. A couple seconds at the proper angle on a piece of sandpaper and bam, perfectly sharpened pencil! Awesome.

    How are the colour pencils made? Is the colour mixed with graphite ?

    • @engineeringworld.
      @engineeringworld.  9 місяців тому

      Color pencils are made by mixing pigments or dyes with a binder, not graphite. The mixture is encased in wood to create the core of the pencil. Do yo have any other question, please feel free to ask.

    At 4:12 it shows the "Sandwhich" containing 7 pieces. You can see it again at 4:26. Each "Sandwhich" looks like the right length for a pencil. Then at 4:59 while it shows its going through the planer, it says "One sandwhich produces up to ten pencils". Can anyone explain how it got 10 out of those 7?
    EDIT:Also, what number is 1800 million (@7:08)?
