Learn Calligraphy & Brush Painting

The difference is that an ink stone is designed for grinding ink. The ink stone has a deeper end to store water and a shallow flat surface that is commonly used for grinding ink. An ink well is designed to be used with premade ink since the entire surface is the same flat level. However, some people opt for using an ink well to grind their ink as this is ok to do so as well. We appreciate your questions and I hope that I was able to help.
