I cleaned my pen on a wet tissue and was surprised by the colors that flowed. It was black ink, pure black, but inside was more. I did chromatography on 3 inks black inks I had on my desk. The results surprised me.
I know every sumi painting ink is a different color black. but I didn’t suspect so many colors from fountain pen ink, as it is rarely diluted.
I decided to try chromatography on sumi ink made for painting and calligraphy. Here is some ink from some of the ink sticks I use regularly. There are both Japanese and Chinese, black ink. Traditional ink. I was surprised by the difference.
