What are some of the uses of sketching pencils

Sketching Pencils are used a lot in drawing, and in order to create drawings with better results, you need a pencil that works well. Below I will introduce you to the usage of sketching pencils, I hope you like it!

Use of sketching pencils

The lead core of sketching pencils has different grades of softness and hardness. Hard to "H" as a representative, such as: 1H, 2H, 3H, 4H, etc., the larger the number in front, the stronger the hardness, that is, the lighter the color; soft to "B" as a representative, such as: 1B, 2B, 3B, 4B, 5B, 6B, etc., the larger the number of softness the stronger, the more black the chromaticity; student pencils are generally HB-shaped, soft and hard moderate. For beginners to learn to draw from HB to 4B in the choice of three types can be.

How to sharpen sketching pencils

Sharpening into a square tip: This sharpening method is relatively difficult, because both the pencil to sharpen, but also to sharpen into a round shape, which requires extremely skillful techniques, without extensive practical experience can not be sharpened well. First hold an ordinary pencil sharpener at an angle of 60 degrees to the pencil and sharpen the wood evenly and forcefully downwards, turning the pencil a little after one cut, cutting in another part, and so on until the lead is exposed. Repeat the above action, so that the pencil's lead exposed part of the longer, generally speaking, the sketch pencil's exposed lead has a centimeter or so on the line, not too short, too short is not easy to use, too long is easy to break. Wait until the lead exposed long enough, began to use a knife cutting pencil lead, in order to cut into a square head, to all four sides have to be cut, must be careful, otherwise it may be broken, really to cut to satisfaction.

Sharpening into a pointed tip: this method is relatively simple, the same method with the method of sharpening into a square head, just the final cut of the lead, we have to be careful and even on each side of the cut until the pencil head is rounded, the pencil head should be careful to pay attention to the top of the thick bottom tip, so that both good and durable.

Note on the use of pencils

1, the pencil lead is toxic? In fact, pencil lead is not poisonous. Lead is poisonous, and the main raw materials used to make pencil lead are graphite and clay, so of course it is not poisonous.

The pencil's core is mainly composed of graphite and clay, graphite is a scale-like solid with a metallic luster, in which there is a carbon-carbon chemical bond between the layer and the layer is Van der Waals force, carbon-carbon chemical bond is very stable, want to destroy is very difficult, which is why diamond and graphite are made of carbon, but the difference between the physical properties and the price is very large, there is nothing in the body can destroy the carbon-carbon chemical bond, so surely, the pencil core is toxic. Carbon chemical bond, so sure that the pencil lead is safe (unless it is added inside the clay harmful to human health).

2. Is the pencil lead metal toxic?

The appearance of the pencil lead has a wrapped mold or pencil paint technology, on the one hand, can protect the pencil, on the other hand, increase the beauty, but the pigment will contain trace heavy metals, a small amount of contact will not have an impact, but the bite of the pencil to eat in the mouth is still not good.

Pencils for sketching

When it comes to types of pencils, they range from 9H to 9B (and now 14B, and softer pencils) There are more than 20 types of pencils, each with a different hardness and depth of color. Out of so many types of pencils, we have chosen five of them, which are suitable for beginners.

Although these five types of pencils have been chosen, when using HB pencils in this tutorial, you can also use F or B pencils, which are similar to HB pencils. In the case of the 2B pencils, you can also choose H or 3H pencils, so it is possible to expand the range of pencils a little bit.

Drawing with five types of pencils? The KENYU skill ball?

The sketch of "KENYU Trick Ball" was drawn with five types of pencils, each with a different hardness and softness. So, let's explain how these pencils are used in the drawing process.

? Jade Trick Ball? The finished drawing. The main part of the Sword Jade Trick Ball is wood in primary colors, and the ball is a green wood product. The picture above is sketched in the order of HB, 2H, 6B, 3B and 4H pencils.

The HB type is the most commonly used pencil Starting with drawing the outline of the object, the HB pencil comes in handy. When sketching, you have to draw auxiliary lines and then start drawing the outline. These auxiliary lines and outline lines will eventually disappear or become blurred. So? It's easy to draw.
