I got in 3 new inks, what is everyone's favorite? The first two are iron Gall inks and darken over time after writing. The third is a pigment ink and won't change much.
@freemo How long do they take to get darker?
@Surasanji While your writing there is a notacble change, but it continues to darken over 24 hours more slowly. It is Iron Gall ink so the type of ink they used thousands of years ago.; Its basically acid on paper with a little pigment. I'll get a picture right after I write something to show the transition (first part will be dark second part light.
@freemo writing with acid seems pretty metal. Still, I'd like to see what they look like given a little time.
Does the iron gall ink degrade the paper over time, or is the effect neutralized by the time that would matter?
@Surasanji Here is a comparison of the same thing i wrote. One is about 5 seconds after writing it, the other is about a minute.
Old school iron gall was strongly acidic, since it had no pigment in it. So it would be destructive with letters litterally being burned out of the page leaving a perfect letter shaped hole. However despite being so strong many documents survive thousands of years without that problem too.
Modern variants of iron gall arent as acidic as they use a bit of pigment too. So modern forms shouldnt destroy the paper. Check back in 1000 years though.
@freemo it looks like it helps to homogenize the writing where lighter strokes are, making them darker to match the rest of the writing. That, I think, is pretty cool.
@freemo anything that can record knowledge that will last for 1000 years has got my vote.
@Surasanji Mine too :) It was why I bought it.
@freemo it's even cooler that it's a proven tech. Modern forms of recording don't have the time behind them, yet.
@Surasanji That was my thinking. Pigment ink is supposed to be better in theory because it isnt water soluable and is just suspended particles. But until it lasts the test test of time who really know.
@Surasanji Thats just because the parts with different levels of ink deposited darken at different rates. When I use a normal ink the coloring is already pretty uniform.
The main advantages ofiron gall is they dont bleed or feather even on shitty paper, and they are thousand year permanent.
