SamCapote Posted September 19, 2011 Author Share Posted September 19, 2011 Hello Sam, Thank you for providing this useful formula; while we're on the subject, do you recommend adding Phenol to uninfected inks to PREVENT contamination? If so, should we follow this same formula or use a little less in non-infected specimens? All the best, Sean The lesser amount (and qualifiers) in post #37 is for prevention. I don't think anyone needs to do this unless they are crazy like me and have a large number of inks that they want to preserve for as long as possible. Originally this started because I began to see that some ink makers did not use adequate (or any) biocides. The only promoted option out there was using Tryphon's Ink Safe or Steril Ink, neither of which worked even in doses 30-40 times as strong as Giovanni told me by phone. So the hunt began, and knowing that almost all ink began using phenol for a biocide before preposterous rat testing mega-doses gave it a bad reputation. Based upon what pharmacist said, I cannot recommend phenol for inks that likely have a pH higher than 8.0, which appears to be some number of the Japanese Sailor & Iroshizuku brands. However, more color varieties within those brands need to be pH tested before that becomes a hard and fast rule. As you know Sean from having made your own inks, there are also other very effective commercial biocides such as Dowicil-75, salicylic acid, sodium azide, etc. but they have significant obstacles for the average FP user. With the new FPN rules, now I REALLY don't know what to put in my signature. Link to post Share on other sites
edmund Posted September 19, 2011 Share Posted September 19, 2011 Since salicylic acid works as a biocide, I wondered if aspirin would work - its not that easy to get salicylic acid . In water aspirin decomposes to acetic acid and salicylic acid - thats why old aspirin can have a vinegar smell. 1 aspirin 325mg will yield about 200mg salicylic acid.My bottle of uncoated aspirin tablets lists only starch as an inactive ingredient. I expect that that will be filterable with any SITB with a paper coffee filter.I made up a 500ml bottle of ink diluent using Pharmacist's recipe using 5 regular uncoated aspirin (5 x 325mg = 1625mg) and then filtered it through a coffee filter to filter out the starch from the tablets. I hope the aspirin decomposition will do the work of the salicylic acid Link to post Share on other sites

Hello Sam, Yes, I know; I am aware of Phenol's limitations in alkaline inks. I just wanted to make sure because while I am knowledgeable about Dowicil 75; I've NEVER worked with Phenol before... at all. I just wanted to make sure I don't add too much; fearing that it may have an effect on flow or lubrication, (both of which are very important facets to me). Thanks again.

So the extensive research using phenol with inks had been done, and it is readily available in the 4% concentration I listed about 4 posts earlier.

Fabienne Posted October 30, 2011 Share Posted October 30, 2011 this is just fascinating, Sam. I was wondering what this persistent and beastly infestation is. What kind of a recurrent critter has gotten loose in this ink. I am assuming that there were other people who had this problem and around the same time as you did? If that is so, then perhaps deA had a dirty batch of bottles into which they poured their product? I guess I like a good mystery, too. I have a bottle of their Vanilla ink I got from Art Brown about 2 wks ago and nothing has happened to it but I am keeping my eye on it none the less. It's for Yew! Link to post Share on other sites
SamCapote Posted October 30, 2011 Author Share Posted October 30, 2011 (edited) That's the worst part of the whole thing. I confirmed it is a fungal infection from microscopic exam (and photos were shown in the other thread). I confirmed it was present in other (normal round) bottles on the shelf at Art Brown's before the three separate shipments of the specialized wedge shaped bottles were sent to me (via Art Browns). There was an initial admission of the problem from Dr. Jansen at DeAt., which he attributed solely (in writing) to the Italian bottle maker that had not cleaned them before sending to DeAtramentis. No further explanations were given, or problems admitted to after the 2nd and 3rd replacement shipments directly from Germany were also contaminated with fungi, and after Dr. Jansen complained about how much extra time and expense it cost him to rigorously clean and sterilize all the replacement bottles. I can imagine that one possible option a corporation may employ--based on fear of the fallout--is the "ostrich strategy," but to be fair, I don't know what actually happened, nor how widespread, how far back, or if the problem is still ongoing. Personally, I am more inspired and confident by the way J. Herbin dealt with a similar issue, and noted in their pinned thread above. One of the problems with this particular (DeAtramentis) type of fungal contamination is that it never developed into an obvious jelly-like glob, or a white floating colony. It would be nearly impossible to see it in medium to dark ink bottles. I only saw it accidentally when holding up and admiring the shade of a light yellow/orange color in the narrow wedge side of the bottle Almost no one is going to routinely examine an ink against a backlight in thin vials or under the microscope, so I cannot comment beyond what I know as fact. The best news for me personally is I have effectively filtered and treated all the previously contaminated ink with effective biocides, and all are looking perfect as of 2 weeks ago. I will start using them after a full 6 months post-treatment has passed--which will be Feb 2012.

WOBentley Posted October 30, 2011 Share Posted October 30, 2011 (edited) Sam, Great work and a great service to the FP community. I have an Esterbrook dipless double desk stand that I will be using the phenol in (already obtained, Natural pigments was very easy to work with and it turns out a good resource for me Wife who is an artist!) to prevent biological growth. I am trying to decide if I will be routinely adding it to open bottles...but there seems to be little risk of harm. Now if only there weere a list of inks with pH values above 7.8 (to be safe I might use this instead of 8.0 :embarrassed_smile: )Thanks!

HesNot Posted June 3, 2013 Share Posted June 3, 2013 Really interesting post. I've been on a bit of a fountain pen exile for a year or so - lots of factors but had basically tuned out a bit and was focused on other things... So I missed the J Herbin party until one day my vintage Aurora 88P filled with Eclat de Sapphire stopped writing properly and filling properly. I sat it aside for a bit and uncapped a week or two later to start cleaning it out to discover mold on the nib. I threw the bottle away and finally have managed to clean out the pen which has been a real nuisance to say the least. While I appreciate their candor and handling of the situation - I admit I'm still a bit miffed as the $8 bottle of ink is the least of my problems - it is the infected pen. Thankfully I only filled one pen with Eclat so I don't have a run through others... Anyway - I have a new appreciation for the challenges ink makers suffer from. 30 years of using a fountain pen and this is my first encounter with SITB - so I should consider myself fortunate I suppose... I'm now pondering adding a bit of something to my open bottles - I don't want to go through this process again! A pen a day keeps the doctor away...

amberleadavis Posted June 3, 2013 Share Posted June 3, 2013 I found myself in a similar situation yesterday. A Goulet sample of JH Eclat Sapphir (or however it is spelled) had slime. I hadn't used the sample since I did some of my first fade tests - so, I've probably had that sample 2 years or so. Overall, I am glad I didn't have a big bottle and I'm glad Sam did these tests.

saskia_madding Posted February 12, 2014 Share Posted February 12, 2014 Thanks for that. I've bought three Kobe yellow ink bottles and all of them had suspicious flakes. I'm sure it's nothing, but after the awful incident that took out a bottle of Penman Emerald, I want to be careful. I'm getting some right now! http://www.fountainpennetwork.com/forum/index.php/topic/261536-about-my-reviews/ Link to post Share on other sites

I found myself in need of "cleaning" some shady ink bottles (some showed things floating, others looked hazy) .. and I am glad to report that after following all your instructions... THEY ARE NOW HEALTHY CLEAR LOOKING INK!!!! ( ..With a strong smell of Phenol.. ) It has been more than 6 months and they are still quite healthy looking. Thanks SOOO much Sam !!!

lapis Posted February 13, 2014 Share Posted February 13, 2014 +N on that. Yes, I favour phenol, one reason why I love Sailor's. I detest any of these made-up junk imitation additives. As said, go for the real thing. Sodium azide (NaN3) is even more potent but more poisonous and much harder to get. Mike Life is too short to drink bad wine (Goethe) Link to post Share on other sites
SamCapote Posted February 14, 2014 Author Share Posted February 14, 2014 Thanks for the kind words. It's great to have a way to protect your inks if you get a lot of them. Reminder that phenol is not as effective with the higher pH seen with some Japanese inks. With the new FPN rules, now I REALLY don't know what to put in my signature.
