  1. I went a bit stir-crazy after tendonitis in my wrist first struck my writing hand, and stopped me from wielding a pen painlessly. In the first three months, not only did I spend more money on pens that I couldn't immediately use, I also bought myself a pH meter on eBay (which would only be shipped from the US by way of its Global Shipping Program for some nebulously calculated postage and 'import fees' totalling 75% again of the price of the item itself). It was something I could use without exacerbating my condition, to find out some attribute of each ink, but I didn't stop to think clearly a

    Celluloid-Safe Inks

    This must've been covered elsewhere (but I couldn't find it) -- I've been using Akkermann ink (mainly Shocking Blue and, recently, Karmozijn) with my Omas celluloid pens -- and, for the most part, had no pen/ink-interaction issues (I hope). Lately, I've also added Iroshizuko kon-peki to my small ink collection. Anyways, today I've looked at the colorverse 'crystal planet' review, and the mentioning of that ink's ph (together with some grim pictures from RichardB's website) made me wonder -- has anyone experienced any problems using these inks (akkerman/iroshizuko/colorverse) with celluloi
  3. In seeking out archival inks... and scouring various web sites and reading about all sorts of things I'm still left feeling a bit befuddled - as googling can often do to a person. I think the three main issues are: Waterproofness, light fastness (UV resistant), and ph neutrality. What I've realized is that a lot of fountain pen people seem really worried about these things as they relate to their pens. As in ruining their pens with the pigments in waterproof inks, worried about a highly basic or acidic ink ruining their pens. I'm not so concerned about that. I like my pens but more imp
  4. 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

    Celluloid-Safe Inks

    I know this is not an infrequently posted topic, but I am having trouble finding the answers I need. I recently purchased a celluloid pen (Visconti Wall St LE) and I am concerned about maintaining the celluloid as well as possible. Up until now I've been using PR DC Supershow Blue as my standard blue ink, but it is quite saturated and I have no plans to put that in the Visconti. I do need a replacement blue though, so I was curious to see how safe some of my options were. I am aware that Pilot and Sailor inks tend to be quite basic and may be able to damage Celluloid. I am especially concern

    What Exactly Is 'ph'?

    Hey all, just a few questions: What exactly is 'pH'? To my knowledge it is how acidic an ink is or something? What does it mean if an ink is 'pH neutral'? How does the 'pH' level affect my FP? What is the difference between Iron-Gall and Dye-Based inks' 'pH' levels? And lastly; Can IG inks be mixed with standard (dye-based) inks, just something like Diamine or Waterman? I've seen R&K inks can, but I've also seen many posts about Diamine's Registrar's turning cloggy, even if mixed with less than a drop of other ink. Sorry for the "few" questions, but I am still quite a novi
  7. So I've recently joined the ranks of vintage pen lovers with my (new to me) Greg Minuskin stubbed Parker 51. I adore the pen, but when I purchased it, I was strongly cautioned against using Noodler's inks. Noodler's has been in regular rotation for me since I got into fountain pens in a serious way about 5-6 years ago. I've been using it regularly in my Pelikan and Edison pens without problem. Now that I have the Minuskin 51, I have the vintage pen bug and want to buy more, but I'm concerned about inks. I also miss (and quite frankly could use) the water resistance of my old favorite ink
  8. I've noticed people saying (often citing Richard Binder's site) that heavily alkaline inks are not to be used in celluloid pens, as they can cause damage or "melt" the body. From what I've seen and searched, there's no real threshold for an ink to be alkaline enough to dissolve celluloid. Some consider pH levels up to 8.0 or 9.0 to be "neutral," but how safe are such pH levels truly for celluloid? Say, if I want to put Iroshizuku or a Sailor ink in a Vacumatic, what can I expect? What about Waterman Red or Noodler's black (assuming I wasn't worrying about staining), which are both slightly alk

    Ph Of Montblanc Mystery Black Ink

    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,
