Excellent quality, very good price/quality , they are great for my vintage pens as well as for my modern pens…they are…Rohrer&Klingner inks made in Germany ( since 1892 )
A few weeks ago, we asked people from the great and unique Fountain Pen Network forum as well as the french forum to give us questions , and many friends helped us with different questions.
Un grand merci to Mr Johannes Rothig from Rohrer&Klingner who helped us.
Here are the answers to their questions and some great pictures from their factory.
Does R&K plan to introduce any additional colors in the future (especially their iron-gall ink colors)?
Dark blue ink: I would like to know if they are planning to introduce other colors?
At the moment we have no concrete plans to introduce new colors. With 18 shades we have a wide assortment and the possibility to mix different inks opens the customer nearly unlimited opportunities. But we do not except it for the future. For a dark blue you could mix blue royal blue and some drops of a red color.
At the end of the year there will be a limited edition of 500 bottles at the japanese marked deep blue ink.
I see that R&K calligraphy ink is available in different size bottles up to 1000 ml, while their “writing ink” (fountain pens) is available only in 50 ml bottles. Is R&K writing ink available in larger bottles?
Can this be special ordered through a seller?
The calligraphy ink is not for calligraphy only. It is used for drawing, airbrush and other techniques where you need a greater quantity of color . Therefore the larger bottles are requested. Today hardly anyone need and want more than 50 ml of writing ink. So it is not possible to offer a large bottle economically.
Was there a reason from changing from the white plastic bottle cap to the silver metal (which has a shorter life as it bends & dents easily, especially in shipping)? If I could choose, I would prefer a black plastic cap, as available on the calligraphy ink.
We wanted to make a larger difference between the writing ink and calligraphy ink to avoid confusion. To protect the cap and the bottle, we are planing a single packaging for each bottle.
Why does R&K not recommend that Sepia be mixed with other inks unless it is used immediately? Is there a PH difference? What is the reaction if it is stored for a long period—sludge?
About the Sepia ink : why a mix ink made with Sepia ink have to be used immediately and the pen cleaned after use?
Sepia contains a dye that is not compatible with the dyes used in the other inks. This could lead to flocculation.
Does R&K supply ink to other companies, which is then sold under their respective label? While there are many brands, I understand that there are in fact few actual manufacturers of ink. I suspect that Montblanc Racing Green was in fact a blend of R&K inks (which they may not acknowledge) ?
No, we do not supply our inks to other companies who sell it under their respective label.
Are there any plans to set up a US distributor so that retailers in the US can obtain it more easily?
At the moment we have no distributor in the US. Interested distributors are invited!
Why is “cassia” called cassia ?
This color was inspired by cassis, the french name of black currant. Cassia sounds more compliant.
If they have considered a different bottle type for their writing ink–something easier to fill pens from to allow the use of every bit of ink ?
We are not planning a new bottle. To use the remaining ink simply pour it into the cap or fill the old bottle with new ink. Please do not pour the old ink in a new bottle. The ink could go off if you do it often.
Your Antiktusche calligraphy inks make a wonderful, muted retro palette. When are you going to introduce these colours in fountain pen ink?
“Antiktusche” is a completely different formula. It is a pigmented ink therefore you can not use it in a fountain pen. You can not have the color effect of a pigmented color with a dye ink. This is a technical limit.
Have they considered added an iron-gall brown or sepia?
Not at the moment.
I would like to ask how they come up with new colors. What is the process of choosing a particular hue of red or green or blue and how they translate that choice into a very consistent and excellent ink!
For a new ink we take some dyes and try to find a hue. Later it is a lot of writing and mixing with special additives until you have a good ink.
Ask if they use a reliable biocide to preserve long term; if they have the pH ranges of them. Ask them about mixing compatability, and if any new colors are planned. ?
We use not a biocide but a preservative. It has no influence on the pH and and protects the ink for a long term. All inks could be mixed with each other. Mixtures with sepia should be use immediately and not be stored.
Could you ask them whether or not they plan to widen distribution in Canada?
It is the same like the USA: Interested distributors are invited!
I would be interested to know whether Rohrer und Klingner could advise whether it is safe to mix any of their non-iron gall inks with Salix and Scabiosa. ?
Yes it is.
Please ask if they will release more waterproof inks or waterproof versions of their current inks that are not currently waterproof.?
No, it is not planed.
Again, i would like to thank you all the people from the forum as well as the kindness of all the Rohrer&Klingner team
