How to configure the glue alum water in Gongbi Chinese painting? What is the specific ratio?

Stroke strokes. It is inseparable from gum alum water, its preparation method is simple, the key is that the proportion of gum, alum and water should be appropriate. You can use yellow gelatin, or you can use edible gum, both of which are small granules and pale yellow in color (gum and alum.

Chemical stores generally have **). The preparation method of gum alum water is: two parts of gum and one part of alum, soak them in boiling water respectively, pour them together and add appropriate water.

Note that the alum is ground into fine powder to dissolve, and the foaming glue is boiled in boiling water, not boiled in water, because the adhesion of the glue will be weakened if it exceeds 100 degrees.

Generally speaking, to draw a four-foot-three-open cooked rice paper painting, you can use two parts of glue and one part alum with half a cup of water on the top of your little finger. Specific experience can only be gained by the author through multiple experiences in practice.

1. Refers to the fine brush paintings drawn by many renderings. 2. The name of the Chinese painting technique. Gongbi heavy color to accurately express the image structure of the object, to achieve a bright, beautiful, heavy artistic effect, must be obtained from repeated rendering, over and over the accumulation of swirls, the ancient name of "three alum nine dye".

After the paper silk is dyed several times, the bottom of the paper is touched, and the re-dyeing is easy to be turbid and uneven. Apply lightly with thin gum alum water to fix the bottom, and then dye it after drying, so that it can still keep it fresh. Once for each several dye alum stains.

Can be dyed repeatedly. Eight or nine times. This method should be "light color is wonderful, those who deepen it are gradual, and those who are thick are layered with thin".

Alum is alum, a colorless translucent crystal. Alum plays an isolation role in painting, and "three alum and nine dyeing" is to use alum to fix the color. Pay attention to the amount when using alum, because alum is very damaging to the paper, will be corroded, and affect long-term preservation, so there is a saying of "biting the paper".

In the production of gum alum water, the proportion of gum alum is generally "two gum and one alum, two catties and a half of water", that is, 60 grams of gelatin + 30 grams of alum + 1250 grams of water. This ratio should also be adjusted appropriately according to the cold and warm weather and cloudy and sunny weather, "six glue and four alum in summer, eight glue and two alum in winter, and three alum and seven glue in winter" should be flexibly mastered.

Draw a four-foot-three-open cooked rice paper painting, and use two parts of glue and one alum with half a cup of water on the top of your little finger.

Glue: Glue is the most commonly used medium agent for heavy color painting, one is only the pigment mixed with glue can be painted, otherwise the toner can not be fixed; Second, it plays an important role with alum when handling paper. The gum here does not refer to chemically synthesized gum, but to the collagen of animals.

In Japan, the best glue is Sansenhon, which is often used for fine paintings and cultural restoration. In China, the glue most commonly used by Gongbi heavy color painters is "gelatin" treated with cowhide. In addition, there are also granules from foreign countries, which are often used because of their convenience.

The best glue is said to be Japan's Sansenhon-gum and deer gum (which are divided into soft and tough deer gum and dry deer gum, which refers to the degree of speed at which the pigment dries up). But for most of us, I think "gelatin" and "granular gum" are the most cost-effective. Because the 3,000 gelatins restored as cultural relics are extremely rare in the mainland, and they are very uneconomical.

However, "gelatin" is available everywhere, and "gelatin" is the glue used in Chinese painting since ancient times, and there is nothing bad about it. In addition, the processing of granular rubber is relatively simple and very cheap, which should be said to be very desirable. Alum:

That is, to specify alum. Alum is best served in powder form for ease of use.

No, in order to prevent the phenomenon of alum leakage after the color, it is necessary to use glue water.

The role of glue alum in painting can not be ignored, it can make the color adhere to the picture without peeling off, due to the effect of glue alum, the color after dyeing or rendering is not confused, otherwise the picture is dull.

In the process of painting, with multiple renderings or too much water, it is easy to cause leakage. After the alum leakage, it will seep water, the color is uneven, and one piece is deep and one is shallow, which affects the picture effect.

After the alum leakage, it will seep water, the color is uneven, and one piece is deep and one is shallow, which affects the picture effect. To learn to prepare gum alum water by yourself, every few times the color is applied to the gum alum water, which can not only fix the color, but also prevent alum leakage.

Techniques for using glue alum water in gongbi painting Do you have to brush alum water in gongbi paintings?

Hello, the fine brush painting must be made with glue alum water. This is mainly to prevent the phenomenon of alum leakage after being fooled by color. The role of the crime painting process is not negligible, it can be the color attached to the picture without peeling off. Otherwise, it will dull the picture.

The ratio of alum to gum is 3:1.

First adjust it separately, boil the glue with hot water, then use cold water to open the alum, pour the alum into the glue after opening, and then use gauze or something to separate the slag, the color is a little yellow is almost the same, too much glue will be brittle.

The proportion of gum alum is generally "two glue and one alum, two catties and a half of water", "six glue and four alum" in summer, and "eight glue and two alum" and "three alum and seven glue" in winter.

The ratio of gum to alum water is 7 grams of gum: 3 grams of alum: 200 ml of water.

Soak two parts glue and one part alum in boiling water, pour them together and add appropriate water. Boiling water for foam glue should not exceed 100 degrees, and the adhesion of the glue will be weakened.

Glue and alum are available in chemical stores and art supply stores, and they are afraid of fading when painting heavy colors to play a reinforcing role. The glue and alum are soaked with water and stirred well, but the longer the alum water, the better, and the glue is soaked with use, and it will stink if you don't use it.

The color is very heavy, and when you are afraid of fading, seal the alum, usually when the work is completed, it is just ordinary alum. Alum. The concentration of alum water is very important, too light will not have a good effect, and if it is too thick, the paper will become very brittle.

The glue and alum are mixed in a ratio of 3:7 and soaked in warm water. It is used when the drawing paper is worn and leaking.

In the process of painting the painting, the glue water is an indispensable part, and it can be said that the painting can not be carried out smoothly without the glue alum water.

The role of gum water:

1. Make the paper not faint, the traditional painting is to paint on cooked paper and cooked silk, and now it can also be painted on leather paper, Korean paper, chemical fiber silk fabrics, cloth, cotton and linen, and a variety of materials. The cooked Xuan used in the traditional Gongbi painting is made of raw rice paper by boiling and hammering the alum, so the cooked rice paper is somewhat brittle, colored, and generally commonly used, boiling hammer Xuan, Ice and Snow Xuan, mica Xuan, raw silk is also used to mature silk by this method, cooked silk is also called painted silk, and other textures of painting paper must also be brushed twice with glue alum water before painting, coloring and smudging with ink, brushing with glue alum water, it will not be dizzy and impermeable, it has water resistance, and can be rendered repeatedly.

2. Fix the color and paper, can make the color and the paper continue, prevent the color from peeling off the paper, if it is a few times, every one or two times to put on a layer of glue alum water, especially the color of the base color, this is to prevent the color from being painted again, the color under the bottom is shaken, such as a layer of cinnabar first, if there is not a layer of glue alum water on the rouge, cinnabar will be turned over the pulp, the Qing Dynasty painter Yu Feiyan put forward three alum nine dyeing means that after painting three times, brush on the glue alum water, dry and then dye three times, but generally dyed many times, Fix the color with glue alum water, and render it repeatedly, so that the color is firm, does not mix colors, and does not turn the slurry.

If you paint a painting, leak alum, you can use glue alum water, the matching ratio is seven glue and three alum, pay attention to this ratio, more alum will hurt the paper, the paper becomes very brittle. It is better to soak it in warm water.

OK. The point is that gum water can play a role in fixing the color.

No, wouldn't it be nice to buy cooked Xuan, and it's not ancient.
