Chalk, brushes, pens and pencils, what are their characteristics and uses?

Brush to the bamboo as a pole, animal hair for the nib - "pen" the origin of the word probably also out of this. Animal hair soft and hard moderate, strong water absorption, used in calligraphy and painting, smooth and free, in the Tiden line between, quite rich charm. No wonder it has always been in the "four treasures" of the first? Think about it, whether it is Wang Xizhi's grass or Qi Baishi's ink shrimp, how can we get away from it? But because of the brush on the grip posture, pen speed and other aspects of the requirements are quite high, this quite artistic pen only in China and some countries in the East to promote and pass down.

Pencil:

In the meantime, there was a small episode in the pen family, and that was the appearance of the pencil. This method has been used ever since the ancients discovered that writing could be scribbled on sticks of charcoal, and discovered that graphite could also be scribbled on. But no matter the charcoal stick or graphite, directly in the hand are very easy to stain the hand, the clever human in the carbon stick and graphite stick plus a layer of "coat" (mostly cork). The problem is also solved. So the pen family has a small member, its biggest advantage is that the handwriting is easy to change, eraser, handwriting, is a good partner for children who are learning to write, but also a painting friend.

Fountain pen:

Pen family "junior" - fountain pen appeared in Europe. Fountain pen, also known as a tap pen, it is based on the principle of air pressure made of a portable pen. Pen gallbladder is empty rubber cylinder, squeeze it so that the air is discharged, after letting go inside the air volume increases, the pressure becomes smaller, inside and outside the larger pressure difference so that the ink is sucked into the pen gallbladder. When writing, the ink is pressed in under the effect of gravity with the nib out. In this way, when writing, you do not have to keep dipping ink, greatly saving time. And writing is very smooth, convenient, well-proportioned and beautiful handwriting, so the fountain pen soon replaced the feather pen, popular all over the world, it is really "blue but better than blue" ah!

The fountain pen is the proud son of the family of pens, it is practical, beautiful, smooth writing, convenient, many varieties and brands, for other pens less than.

My little fountain pen is very cute. Its body is like a thick willow, and like a column in the ant world its hat is golden, above a golden braid, but also flashes a sharp sword general golden light. Open the hat and look at its beak like the beak of a kingfisher. Its body can be twisted and unscrewed to be the belly armor and stomach. I give it every week to eat, so that its stomach is full, so that the small pen can help me work.

Ballpoint pen:

And then later, Westerners invented the ballpoint pen which is more convenient for writing. Its main part is the ballpoint core, which consists of a hollow plastic tube like a feather rod and a nib with a movable metal bead (hence the name ballpoint pen). Since the plastic rod is filled with oil-based writing material, it avoids the trouble of fountain pen ink leakage, and the writing time is longer (generally a ballpoint core can be used for 2 to 4 months). This ballpoint pen due to more lightweight, more convenient, more economical, become the pen family "favorite", by the people of all walks of life, especially young people's favor.
