Scientific American Article From 1959, On Ink-Nib-Paper Relationship
TenBladeSummitar posted a topic in Th-INKing Outside the Bottle
An interesting article from Scientific American New Scientist (edited - thanks to those who pointed out the error), 1959, outlining the history of the development of quick-drying fountain pen ink, and how the ink and paper interact to influence perceived feathering or line spread. It also is clear how ink recipes can affect pen components or reliability thereof. http://bit.ly/Science_of_Quick_Drying_Fountain_Pen_Inks -
Why is Noodler's Baystate Blue advertised as being alkaline? The bottle says ph between 8-9, and various retailers advertise it as being slightly more dangerous to pens due to being basic. Yet, many sites including richardspens.com and a thread here quote the pH as acidic, in the 4-5 range, and when I pH tested my bottle in lab today with a ph probe I got a pH of 2.96, which is 1,088,484 times more acidic than the quoted pH. (pH is measured on a logarithmic scale with a pH value representing a Hydronium Ion Concentration of 10^-pH molar, so pH 5 is 10 times more acidic than ph 6, which is 10 times more acidic than pH 7, and so on). Could Nathan have meant to list 8-9 as the pOH? I can't really think of any other explanation. Edited to say: Even if he did mean pOH, that would only mean a pH range for the ink of 5-6. Measured values have been significantly more acidic than that, by a factor of up to a thousand.

Hi, So I have a bit of an odd question. I dye my own wool to spin or felt, and on occasion I use fiber reactive dyes to dye plant based material like bamboo or cotton. I was wondering if I could try using the fiber reactive dye to create my own ink. You use Soda Ash to set the color so it would need to be in the "ink". Will this be an abysmal failure or should I give it a go and see what happens?

Chemistry Question: Chlorine + Ink Interaction?
TassoBarbasso posted a topic in Paper and Pen Paraphernalia
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 -
Dear ink testers, Has anyone tested the pH of the Montblanc Mystery Black fountain pen ink? I don't have litmus paper or pH meter. Thanks,
