What is the difference between a pen and a pencil? The pen is ink、Pencils are...graphite, right? I would say it's almost a passing grade.、Pencils that draw with pure graphite (it looks like graphite held between chopsticks) were only available in the very early days.、Nowadays, we mix clay with it.、made by firing。If the proportion of clay increases, H,2H,3H... and getting hard。15It seems to be surprisingly normal up to about H.。
Pens use ink、The pen is “between” the paper and the ink.、It's more indirect than a pencil、When I use a pen, it briefly touches my head。There is something called a “pickled pen”。Stick the pen tip into the inkwell and head towards the manuscript paper.、That's what old novelists do in movies with a cigarette in their mouth.。collect bird feathers、A quill pen with a notch in the shaft、G pen used by manga artists、detailed round pen、Glass pens are also similar (glass pens are more like writing instruments than writing instruments).、Already a craft)。Pencils are also colored pencils、water colored pencils、wax pencil、It has a variety of crayon and facial features.。
I'll change the direction of the story a bit.、Pens commonly used in modern times are、Broadly divided into ballpoint pens and felt-tip pens。Dipping pens are already a classic.、somewhat of a hobby、Isn't it safe to say that it is only used in artistic situations?。Of these two, felt-tip pens are more “primitive”。The principle is to soak one end of cloth or leather in a liquid.、A method in which the ink that crawls up through capillary action is rubbed onto the paper.。In other words, a modern version of “fude”。For ballpoint pens, the inkwell is temporarily covered with a stainless steel ball.、Ink stuck to the side of the pot、Start pulling by rotating the ball while keeping it in close contact with the jar.、something to press on paper。近代的アイデアの勝利。原理は単純だが非常に精緻な技術が必要で、こちらは純然たる精密機器―それが100円もせずに買えること自体が凄いという気さえする。市販のボールペンはひと昔前のものに比べると、格段に書きよくなっている。
