When storing water at ordinary times, the inkstone also needs to be moistened, and it needs to be stored with fresh water every day. The inkstone can't be short of water, so it needs to be replaced with fresh water when it is used. Hot water will damage the ink, remember to avoid it. Use the back brush. After the inkstone is used up, the remaining ink must be washed off and not condensed on the inkstone. Otherwise, the residual ink will form a slag block, which will first hinder grinding and then damage the surface of the pen and ink.

When washing, you can use loofah and other things to help wash, but you can't use hard things to rub hard, so as not to hurt the smooth, beautiful, lovely and generous inkstone surface. If you need to take it out, it's best to dry it in the shade, and don't wipe it with paper, so as not to leave debris mixed with ink.

Be sure to take out the ink after grinding, and don't let it stand all the time, otherwise the ink and ink paste will stick together and damage the ink surface. If it sticks accidentally, don't pull it hard. You can wet it with clear water first, rotate the ink in place, and then take it out after the ink becomes loose.

These three different voices respectively reflect the tenderness and age of Duanyan Stone. The crisp metallic sound of "clang, clang" when striking the inkstone is the best. If the sound is "poof, poof", it means that the stone is muddy or has dark scars, which is inferior.
