Good Question of the Week: Is Waterproof Ink Safe for Pens?

December 19, 2016

A student recently inquired:Hi Marc. I went to a store in Los Angeles today to buy a recommended fountain pen with waterproof refill. The owner did everything possible to dissuade me. She said that the waterproof ink ruins a fountain pen very quickly because the ink dries in such a way that it clogs the pen. Only a dip pen, she said, should use waterproof ink. I didn’t buy it. What gives?

What does Marc say?: “They don’t know about Platinum Carbon Black I guess :)”

Platinum Carbon Black is the ink I use for waterproof drawing. It’s fully pen safe > in my experience < I’ve used it in their name-brand Platinum Carbon Pen, a number of Noodler’s pens, and a number of Lamy pens. (Link to my drawing gear page). There are other nano-particle inks, but it’s the only one I’ve tried personally.

And then, maybe just don’t stop drawing? Don’t leave your pen in a drawer for weeks. Pen collectors might only take out their Aurora Diamante to sign checks for charity donations and real estate deals. Just draw every few days and the ink keeps flowing :)

The thing is, ask an antique car guy about taking care of a car and they’ll say; don’t drive it in the bright sun, don’t let kids in the car, for goodness sake don’t live in a place with winter!

In other words, pen collectors treasure the pens as objects. Artists want to use them into the ground, and treasure the drawings they make.

If Platinum Carbon does shorten the lifetime of then pen – I really don’t care, and I’ll never even know – I buy Lamys for around $40, and hope to lose them in an alley in Macau or a taxi cab in Havana!

    I have been using Koh-i-noor black ink for my fountain pens, It is an ink for technical pens which have very tiny parts.. It seems to be working, And I have heard the same thing from sales people in stores..that it has shellac in it so dont use it in fountain pens. I put it in to my two Sailor Fude pens, my Lamy Joy, not so much in my Namiki Falcon, but I want to..I have tried Noodlers blacks, Eel and Bulletproof black, but they dont seem as black as the Koh-i-noor..
    Goulet pens reccommends De Altramentas Document black but it is $20 for one once, seems pricey. Also most places seem to be out of stock on the Platnium Carbon Black..Thanks for your answer tothis. Seems like so many Urban Sketcher are using fountain pens and then watercolor. We need a good black permanent ink that wont bleed.
    Have a Happy Holidaze!! I am hoping to meet you in person in Chicago!!

      As a side note, Koo-I-Noor used to sell an ultrasonic cleaner for technical pen nibs. I bet you could find them on ebay, and the would work like a charm on fountain pen feed. Device is the same as an ultrasonic jewelry cleaner I do believe.

      • December 19, 2016 11:56 AM

        Thanks , I know about those, good idea, I will look. I use their cleaner fluid, and a syringe. Cleaning often is the key ..in fact today might be fountain cleaning day!!!

    • January 6, 2017 6:33 AM

      I found a fountain pen repair page that recommends the Koh-i-noor cleaning solution in an ultrasonic for cleaning out vintage FP feeds if they’ve had shellac-based ink run through them. It will probably shorten the life of your pen.

      Please, please don’t run shellac based ink through your Falcon! (wincing) That’s a marvelous pen, but in my experience a little more delicate than the Lamys, which are workhorses. What works in a Safari or a Joy may not work at all in a Falcon. Try the Noodler’s Black in the Falcon — they tend to run wet (in my experience) so the black should be nice and dark.

        Just got my bottle of carbon black for my pens will be testing. Thanks

    I started getting into fountain pens during this year’s Inktober. All my pens so far are Jinhaos, Heros or Dukes from Asia (I was using a Shaffer for a while). The ink I have been using in all of them is Hero’s 234. It was praised in different circles as a waterproof ink and, I believe, a carbon ink. It seems more water resistant than waterproof, depending on the paper (cold press works well) and how dry the ink is. The ink disperses more quickly on the paper with straight water but holds quite well with water and pigment. It suits the way I work and at about $6.00 for a 56ml bottle it’s a great deal. It has a rich black finish.
    After almost 3 months I have not had a blocked pen but, as you indicated Marc, I keep them in use as well as cleaning the feed/nib every few fillings.

    I use Carbon Ink and De Altramentas Document black. No problems at all. However, I am constantly using them. If a pen does not get used much I will go back and check on it. I agree with you the key is to definitely use your pens. Pens that are not in used are stored empty and clean.

  4. December 19, 2016 3:55 PM

    I have been using Noodlers Bulletproof black in a Pilot Penmanship and Lamy Safari for years in my watercolors, never had a problem. I am also NOT a pen cleaning fanatic.

      I’ve been using Noodler’s Black and Lexington Grey for years in Lamys with no problem. I clean them occasionally with distilled water. Lexington Grey is my favorite sketching ink. Almost black and a bit more interesting and waterproof. Lots of tutorials on You Tube by Goulet Pens. I love the DeAtramentis Document waterproof inks also.

    • January 6, 2017 6:19 AM

      Second the recommendation for Noodler’s for waterproof inks, which are formulated and time-tested for fountain pens. (The potential exception is Baystate Blue, which is gorgeous but stains like a mofo.) Bulletproof Black is the classic, but there are some interesting different options. Plus Noodler’s is fairly cheap for the giant amount you get. Platinum Carbon is also great.

      Some of the Noodler’s inks are partially waterproof, like Walnut (very dark brown) — this can create interesting effects in a sketch, where the line softens but won’t wash away. (I see that LadyP noted this as well below.)

      India ink (the kind you use in technical pens) truly will destroy a fountain pen — the feed just isn’t engineered for it. If it’s a cheap one, that may be ok with you. India ink, like Koh-i-noor, is for technical pens, not fountain pens.

      In my experience, whenever you can, get your ink from a retailer like Goulet Pens rather than Amazon. First because it’s good to support independent business, and second because they absolutely know what they’re talking about.

      • January 6, 2017 12:01 PM

        I also like Goulet’s Ink Samples – it’s enough to make a half dozen drawings and have a good idea if the color is for you. But – I end up paying duty if I go with them, so up here in Canada there is WonderPens. Also run by a husband and wife team, and also very knowledgeable about pens and inks.

    • January 6, 2017 6:39 AM

      An interesting Noodler’s to try would be Rome Burning, which dries light (kind of funky) brown but washes out to an interesting purple with water. It is Truly Weird to write with, but the idea of using it for ink and wash makes me wanna revisit it for sketching …

      • January 6, 2017 11:59 AM

        Yes Sonia – like this one! https://citizensketcher.files.wordpress.com/2015/05/ink-test_rome-burning_ian-bowden.jpg

          Coooool! :D

  5. December 19, 2016 5:23 PM

    A few years ago, when I started drawing in ink and wash, my local pen shop owner was similarly discouraging….but I found the Platinum Carbon and then the de Atremis ink and have never looked back! I can full endorse your advice! And I do occasionally use an inexpensive ultrasonic jewelry cleaner. Pen stores are missing out on a big market!

  6. December 19, 2016 6:07 PM

    I think your first, short answer, was the best. There is a world of difference between the nano-particle inks and other (india, acrylic) waterproof inks. The nano-pigments also make Platinum Carbon, Sailor nano and DeAtramentis Document inks more expensive than those other waterproof inks.

    Even the fear of letting pens sit around with these inks is unfounded in my experience. While NO ink should sit in pens for long periods of nonuse, the nanopigmented inks are no worse than any of the dye-based inks.

    I currently have seven pens filled with either PCB or DeAtramentis Document inks. I rarely clean the pens and since I can only use one at a time, some go for extended periods without use. – Larry

    I also use Noodlers Bulletproof ink in my Lamy Safari fountain pen, and another fountain pen, and never have had a problem. A fellow urban sketcher suggested to take out the ink every few weeks and flush it out with water.

    • December 20, 2016 8:44 AM

      I’ve been using Noodler’s Walnut (which is partially bulletproof) without problems. The store owner needs to educate himself better.

  8. December 19, 2016 11:13 PM

    I draw with a Platinum Carbon Desk pen with the carbon ink cartridges. I also draw with a Pen & Ink Sketch pen using a converter with their bottled non-shellac india ink. Both pens work awesomely, with weekly use. In my case, I’ve used inks made for each pen.

  9. December 20, 2016 7:50 PM

    good read, shared this on my fountain pen and calligraphy group!

  10. December 22, 2016 12:57 PM

    I am new to fountain pens, I have two Lamy Safari pens and a Noodler’s Creaper…I write in my journal every day and do some sketching with Noodler’s bullet proof ink. So far I haven’t had problems..but the pens I’m using are not expensive so I’m not too worried since I use them daily. I do take good care of them though by keeping them clean.

    I bought Premium Carbon Ink from a seller on Amazon and it was not waterproof at all. Marc said it was probably a knock off. I returned it and got a refund. There is another seller there that I might try but still a bit hesitant right now.

    • December 23, 2016 2:50 PM

      I doubt that it was a knockoff but I’d bet they’re not sending you Platinum Carbon Black but rather sending you Platinum Black, which isn’t waterproof. A lot of the third-party sellers (mostly from China and Japan) don’t seem to be very knowledgable about their own products, often using the wrong photos to represent what they’re selling, etc.

      Buy your fountain pen inks from a place that sells fountain pens. In the US Jet Pens and Goulet Pens are good sources for Platinum Carbon Black. In Canada, Wonder Pens in Toronto stocks it.

      • December 23, 2016 7:03 PM

        I just ordered platinum carbon from China, or at least on Amazon because both jet pens and Goulet pens have been out of stock…we will see when I get it if it is waterproof..

        • December 23, 2016 11:00 PM

          Hope that works out for you. Here’s an example of what I’m talking about. This listing says Platinum Carbon but the picture is of plain Platinum Black (not waterproof)

          https://www.amazon.ca/C-1500-Platinum-Carbon-Black-Ink/dp/B001AVR5A6/ref=sr_1_9?ie=UTF8&qid=1482551742&sr=8-9&keywords=platinum+carbon+ink

          This listing also says Platinum Carbon Black and it shows the proper bottle for their pigmented ink

          https://www.amazon.ca/Platinum-carbon-bottle-black-japan/dp/B0028MTSFQ/ref=sr_1_1?ie=UTF8&qid=1482551742&sr=8-1&keywords=platinum+carbon+ink

          Who knows what will get sent when ordering from people who can’t get this stuff straight in their listing.

          Here’s the listing for Platinum Carbon Black from Wonder Pens in Canada:

          https://www.wonderpens.ca/Platinum_Black_Carbon_Ink_60mL_p/inkc-1500black.htm

          They know what they’re doing/selling and I’ve bought PCB from them before.

          Cheers — Larry

            This is FASCINATING Larry. (Did you guys know Larry is a real detective? Or at least he writes mystery novels :) Check out Her Book of Shadows!

            So, that is some great work on this problem. You see to have cracked the case. I’m going to go double check listings Amazon sends me. Thanks very much for this.

              I bumped into this problem (mislabelling by Asian vendors) when looking for bent-nib “calligraphy” pens on eBay. Some properly identify the bent nib in both photo and in the name (inserting calligraphy into it) while others call them calligraphy pens but present photos of straight nibs. I have no idea what you REALLY get if you order :-) I have had good luck with those who at least keep their photo and name consistent :-)

              Truthfully, for Canadian artists, you can’t do better than buying PCB from Wonder Pens. You’ll find their price to be only a couple bucks higher than the US vendors (much less than the current exchange rate) and the shipping is cheaper because it’s within Canada. Besides, they’re really nice folks, trying to supply we Canadians with good fountain pen products.

          • December 24, 2016 4:57 PM

            here is the link for the platnium Carbon ink I ordered on amazon…https://www.amazon.com/gp/product/B0028MTSFQ/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1
            I guess I will find out,it was shipped…

            • December 24, 2016 6:16 PM

              Well in the picture there it is correct, its the gold label Carbon Ink! Looks good!

  12. January 2, 2017 12:34 PM

    I’ve used Carbon Black in my Lamy vista and haven’t cleaned it in over a year. It’s never clogged or had other problems even though I’ve gone weeks between using it. I think if you buy a high quality ink, it’ll just be safer in the long run.

    • January 4, 2017 12:36 AM

      Haven’t cleaned it in a year! I like the cut of your jib. That’s hard-core. :)

    If you have a very expensive pen, or an heirloom from your grandfather, I understand following these precautions and sticking to inks that are easier to dissolve. But that said, if you know you’ll never use the pen with the water soluble ink, why waste your lovely pen? They’re made to be used! I don’t own any expensive pens (maybe one day…) but in my book, a $100 pen that gets used everyday for five years and then breaks will have earned its price more than a $100 pen that lasts decades but was used ten times.

    And if your grandfather was anything like mine, he would want you to use it! Mine was more of a ballpoint kind of guy, but I have some of his pocket knives and a multitool, and I know he would rather see them covered in woodshavings than left in a drawer somewhere. (I also have his metal stapler which I suspect could be used to bludgeon someone to death and continue to work fine. Stuff was made solid back then.)
