The ink used for drawing and grinding is better.
1. Materials
The main raw materials of ink are carbon smoke, rubber, additives and solutions, etc., which are generally processed by machinery. Ink sticks or ink sticks are different. I often hear people talk about pine smoke ink, oil smoke ink, and lacquer smoke ink. The smoke here is the main component of the ink.
Take oil fume ink as an example. Generally, the best tung oil is used, rushes are inserted into it and ignited, and a blue and white porcelain bowl is placed above the flame. The unburned soot will remain on the inner wall of the porcelain bowl, and the soot will be collected and used to make ink.
2. Effect
The ink is toner. The toner particles are relatively large and can only be adhered to the surface of the rice paper by glue. Over time, the glue will fail and the toner will fall off. , the writing will slowly peel off. The ink produced by ink sticks and inkstones is different. Its main component is soot, and its particles are extremely small. When written on rice paper, it can penetrate into the fiber gaps of the rice paper. It is precisely because of this that the ancient calligraphy and painting can be preserved to this day.
3. Art
Using ink directly has no artistic sense; when the ancients studied ink, it was actually a process of conception and creation.
Extended information
1. Analysis of ink raw materials Black smoke is a black powder produced by thermal decomposition of various oils and fats in an environment lacking oxygen. Raw materials commonly used to make black smoke include: pine wood, tung oil, rapeseed oil, sesame oil, cottonseed oil, lard, whale oil, mineral coal and petroleum, etc. Due to different raw materials, the quality of the black smoke produced varies. .
Second, quality analysis of ink ingots
There are many factors to evaluate the quality of ink ingots, among which the ink color and the dispersion of ink particles are the most important. As far as the type of ink color is concerned, generally Including black, purple-black, dark brown, blue-black, etc. Among them, purple-black is considered the best ink color. Factors that affect ink color include the type of black smoke, the size of the smoke particles, and the age of the ink. The pine smoke most commonly used for making ink is generally blue ink, while oil smoke is dark brown. The longer the ink is stored, the ink color will gradually turn purple-black. .
Although the color of oil fume is not the most ideal ink color, the smoke particles are fine, the dispersion is good, and when the ink is written on paper, it is more glossy than pine smoke ink, so oil fume is considered the best for making ink. Raw materials. The dispersion of ink particles is not only related to the black smoke raw materials, but also closely related to the ink making conditions, the amount of glue used and the storage environment.
Since the ink tablets produced by various brands use different raw materials, formulas, and manufacturing conditions, the quality of the ink tablets varies.
3. Ink production
For those who write and draw, grinding ink is a time-consuming task. Especially for beginners or school students, ink brings great convenience. The main ingredients of ink are similar to ink ingots. However, in order to prevent precipitation and corruption, some electrolytes and preservatives must be added to the ink.
These additives will affect the quality of the ink to a greater or lesser extent. Originally, the glue in ink was still mainly animal glue. In recent years, it has been gradually replaced by synthetic glue, and the quality of ink has also caused many changes. Whether these synthetic glues and additives have adverse effects on the preservation of paintings requires further study.
