The Mohist scripture in Lei Xin of Qing Dynasty recorded: "If you use it every day, you will only get half a cent at the age of one, and you will not change it if you use it." A good Mo Ding, like a good horse, is a scholar's right-hand man. Ink plays an indispensable role in "Four Treasures of the Study". The ancients described the reputation of ink as "gold is not exchanged", which shows its high value.

In recent years, Qianlong Imperial Ink has won sky-high prices in the auction, which once again proves the preciousness of ink. Ink is expensive because its production process is complicated and elegant. Ink is a kind of black pigment made by hand with lampblack and pine smoke as raw materials. Clean water is needed when grinding ink. If there are impurities in the water, the ground ink will be impure. As for adding water, it should not be too much at first, so as not to soften the ink or splash it on it. Should be gradually added.

The skill of grinding ink

1, medium concentration

Clean water should be used for grinding ink. It is better to use less water for grinding ink than to use more water. If it is thickened, add water to thicken it. You can add water while grinding. It should not be too much at first, so as not to soak in ink.

2, 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.

3. Storage box

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.
