Hi All! A "chemical" question: what is the effect of chlorine on inks? I know the impact on the environment and I try to use only totally chlorine free paper when possible, but I'm wondering: is there a difference in the way inks react on different kinds of paper: paper with chlorine, elementally chlorine free paper and totally chlorine free paper? I'm especially interested in the impact of chlorine on inks in terms of permanence: will inks fade away faster on paper that contains chlorine? Will this happen with permanent inks (iron galls or noodlers) as well? thanks, Fabio
