These inks work particularly well with our fountain pens and come in a selection of colors. The traditional bottles are made of glass and contain 1oz. ph scale is 0-14. 7 is neutral. Below 7 is acidic, above 7 is basic. In theory, you want to stay away from heavily acidic inks so as to not damage pens and paper. Our current inks are in the 7-8 range.saturation - how much of the ink is absorbed at full color. Good shading means less saturation, and more shades of the color in writing. Deep saturation means full color.
