The use of ink should pay attention to the following points:
Zheng Mo
Liu Gongquan has the so-called "pen is right", so is grinding ink. If the ink is not straight or oblique, it is neither elegant nor even.
The intensity is even, rapid and moderate.
When grinding ink, the force is too light and too heavy, too fast and too slow, and the ink will be thick and uneven. Too light force, too slow speed, wasting time, floating ink; If the force is too heavy and the speed is too fast, the ink will be very thick and light. The correct way should be to "push hard", the intensity should be moderate, and don't rush it.
Medium concentration
Even the light pen in calligraphy and painting works is written in thick ink. The difference lies in the amount of ink dipped, not the depth of ink. If the ink contains too much water, the pen will spread quickly when it touches the paper, forming ink clouds of different sizes and shapes. How can you have a stroke? But don't overdo it. It's terrible to write with ink as thick as half jelly. You also need to remember to use white paper, especially thick ink. If you use colored paper, it can be a little lighter.
Used with grinding
The ink must be freshly ground, because if the ink is left for more than one day, the glue and coal will gradually separate, and the ink will be dull and not durable, so it is easy for Su Mo to fade when used as a book. Some ready-made inks sold in the market are sticky and sticky, some are too low in concentration, paper is easy to melt when dropped, and there are many preservatives, which are easy to damage the nib and should not be used.
In the locker
After grinding the ink, take it out immediately, and don't put the inkstone pool, otherwise the glue will easily stick to the inkstone pool, and it will not be easy to take off when it is dry, and it can also prevent the water from softening and lose both sides. You can't expose yourself to the sun to avoid drying. So it's best to put it in a box, which is the best way to prevent moisture and avoid direct sunlight and dust.
Why is ink not easy to wash off?
If your clothes are stained with ordinary stains, you can wash them with water. If clothes are stained with oil, they can be washed with gasoline.
However, for ink, neither water nor gasoline works. Because carbon is insoluble in water, let alone gasoline, no solvent that can dissolve carbon has been found.
So, can soap wash the ink out of clothes?
I won't either, because the carbon particles in the ink are very fine and firmly adsorbed on the fibers of the cloth, so they won't be washed off easily like dust.
Is there no way to wash the ink off the clothes?
There is a way. If the clothes have just been stained with ink, soak them in water and wipe them off immediately. As long as it is washed quickly, it is possible to wash it off.
Why can rice grains wash away ink stains?
Because when rubbing rice grains, the cooked starch in rice grains will be rubbed into thick and sticky paste, which will stick to the tiny carbon particles on the cloth fibers and stick together. So as long as it is rinsed with water again, it is easy to remove the ink.
If the ink is dry, it won't wash off easily. Because at this time, the fine carbon particles have been firmly adsorbed on the fibers of the cloth, and the pulp made of starch can no longer stick to the fine carbon particles.
