How is the ink clay made and what is it made of?

Ink clay is the four treasures of our country's study, with a long history, suitable for wooden seals and stone stamps. The quality requirements are bright in color, durable and delicate in quality.

Castor oil 60 grams.

Bright red (or magenta, lead) 11 grams.

White clay (finely ground and sifted) 10 grams.

Mugwort (that is, mugwort is dried in the sun, the hard stems are removed, and the fine fleece is rolled by machinery) 18 grams.

Borneol 1 gram.

Method: Put all kinds of raw materials into the tank in the order of the above recipes, mix them with wooden rods first, and then put them on the rolling mill, and roll them repeatedly for many times to form a mud-like ink.

Note: Castor oil is a dispersant, white clay is a filler, red and other pigments are a chromogenic agent, mugwort is an adsorbent, and borneol is a preservative and aromatic effect.

1. Printing clay: It is an oil-soluble seal pigment prepared by pigments, greases and preservatives.

Second, the production method:

1. Sunning oil: select the best refined castor oil and vegetable oil, mix them in a moderate proportion, place them in an open ceramic or enamel container, cover the glass, and expose them outdoors. After 3 to 5 years, it becomes a usable ink for ink, ready for use.

2. Wormwood processing: Fresh wormwood branches are harvested and dried naturally under the sun. Then the wormwood leaves are picked and selected, the short and easily broken parts are removed, and the long, thick and tough parts are left, which are classified according to their length and the degree of fiber inside, and peeled and processed respectively.

3. Cinnabar selection: the mineral cinnabar is selected in layers. Remove impurities and debris, and select the whole piece of mineral crystal cinnabar with bright color and good gloss for use.

4. Cinnabar grinding: Grind high-quality cinnabar with water in a bowl. Cinnabar is gradually layered during the grinding process. Take the upper and middle layers separately for easy use. The grinding fineness of cinnabar must meet the predetermined standard. The ground cinnabar powder must be wet and dried before use.

5. Oil processing: add necessary additives to the sun-dried printing oil according to a certain proportion and refine the oil to meet the quality requirements of various printing clay selections.

6. Oil sand mixing: add ink and other auxiliary pigments to the cinnabar powder in a certain proportion in the stone bowl to fully mix and grind to form a color paste. The color paste must be uniform and delicate, not thick or thin.

7. Hammering into the velvet: In the stone bowl, the color paste and selected wormwood fibers are mixed in a certain proportion through the traditional manual hammering method, and they are integrated into one to form a printing group. In addition, kapok, wick, bamboo, and lotus silk can all be used to make printing clay.

However, the cotton is soft, the wick stem is rigid, the bamboo is smooth, and the lotus silk is weak, which is not as good as mugwort.

8. Cylinder preservation: The ink can not be used immediately after it is made, and it must be stored for a period of time before it can be put into the porcelain printing box for use.

Inks are oil-soluble stamp pigments made from pigments, greases, and preservatives.

Ink prepared by modern technology. The main components of red ink are lead chromate, mercury sulfide, red powder 88, barite powder, white yanhua, castor oil or chlorinated paraffin oil, phenol, mugwort and kapok. The main components of blue ink are oil-soluble aniline blue, oleic acid, castor oil, etc.

1. When you find that the ink is dry, you can try to heat it first, such as drying it in the sun for about 10 minutes, or using a hair dryer to heat it around the ink clay, the temperature rises, and the ink will naturally become soft.

2. If this does not make the ink clay soft, at this time, you should consider adding some sesame oil, other edible oils are also OK, don't add too much at a time, slowly try to adjust slowly, and wait until it becomes softer, and then continue to stir evenly. At this time, remember not to add water, because the ink is mainly composed of cinnabar, wormwood, and ink.

3. In order not to let the ink mud dry out, pay attention to keeping warm at room temperature when storing it, and the lid should be tightly covered, not stored naked, and avoid direct sunlight. It should be turned frequently to make the internal structure of the ink uniform. If it is used frequently and the mud is dry, you can add special ink oil and cinnabar to help recovery.

The method of using ink is simple. First of all, wipe the pattern or text on the seal with water to ensure that its surface is dry and clean. Then, take an appropriate amount of ink and place it on the seal.

Apply appropriate pressure to the seal so that the ink evenly covers the raised part of the seal. Then, gently press the stamp against the paper or other material that needs to be printed to create a clear imprint.

In addition to the basic usage, there are some tips to help you get better use of the ink. First of all, it is necessary to choose the type of ink that suits your needs. Different inks may be suitable for unobscure stamps and materials of the same type.

Secondly, keep the seal clean and tidy so that it can be easily stamped clearly. Finally, pay attention to the storage conditions of the ink. It should be stored in a dry and cool place to avoid drying or deterioration of the ink.

At the same time, it is better to use ceramic jars and jade jars.

In conclusion, with the proper use and storage of the ink, it is easy to obtain a clear stamp imprint to meet the needs.
