What is the difference between a graphite wand, a drawing pencil and an ordinary Chinese painting pencil?
Graphite is an allotrope of elemental carbon is the most soft conductive minerals. Graphite and its products have the properties of high temperature resistance and high strength. Graphite can be used as a pencil core, pigment, polishing agent. After special processing, graphite can be made of various special materials for industrial departments.The main part of the pencil core is graphite. In fact, the pencil is made from a mixture of graphite and clay at a certain proportion. Such as "H" or "hard" English (hard) on behalf of the prefix, content of clay, pencil hardness to said. The bigger the number in front of the H (such as 6h), the harder the pencil core, the greater the proportion of clay in the cartridge to the graphite, the less pronounced the word, and is often used to duplicate.
Charcoal is the source of raw wood burning container was put into the seal, because the air can not enter the container, not wood burning down. Crunchy texture, porous charcoal, charcoal painting with hardness, very soft, soft, not soft not hard points.General charcoal are used to draft use, easy to modify, draw up very fast, so is generally not as deep drawing tools. The difference in the diameter of the charcoal strips is determined by the size and size of the paintings.
Any painting, as far as tools are concerned, any material will do. The above problem is how we understand the properties of these materials, with a pencil. For example: 2H, HB, 2B, 3B, 4B, 5B, 6B, 7B,,,,, this is a pencil mark label, B number is more and more soft, and will draw more and more black. The smaller the number of B, the more hard, though graphite is a material of the pencil, but with this painting.
