Question: Do Iron Gall inks turn black eventually ? From what I read they are supposed to, but other people seem to say that they don't really. So, if they all turn black whatl's the point of getting different colours ?
I'm hoping they retain some of their colour but just darken - that's the only thing that makes sense to me otherwise it's just different colours temporarily for marketing purposes ? I don't know. Any info on this ?
I only have a couple of IG inks; they share many traits, but in some ways behave quite differently. Both inks seem to darken over the course of minutes, hours and days. I have not yet compared months-old writing samples to determine if they darken appreciably more.
R&K Salix feels "dry" and seems to work best in my "wetter" pens. It goes down blue and darkens to a medium-dark blue-grey. I've tested writing samples for water resistance by soaking them in water... the blue dye component lifts off leaving a medium-gray line.
KWZI Iron Gall Blue Black is significantly "wetter" and goes down a very dark blue. When it cures, it is extremely dark... on some papers (the cheaper more absorbent ones), it is still somewhat distinguishable from true black... while on other papers (Rhodia, Clairefontaine, Maruman Mnemosyne, Kakuyo) it is appears nearly black to me. In water-resistance testing, it is similar to Salix but darker overall... the blue dye lifts off, leaving a very dark gray imprint (noticeably darker than Salix).
Neither is as black as Sailor Kiwa Guro nanopigment ink. If I need black ink, that's the one I will use until I find something I like better.
