DescriptionSpecificationsFrequently Asked Questions
This ink is Noodler’s Ink’s attempt to replicate the color, depth, behavior, properties, and general characteristics of the first royal ink of ancient China. This is the STRONGEST of all vintage emperor/royal inks. Set includes one 4.5 oz eyedropper bottle, one eyedropper fountain pen and one eyedropper brush pen. Ink should be used with enclosed pens or other eyedropper pens only to avoid clogging. You can make your own eye dropper pen with this tutorial.

How does one find the color of the Emperor’s ink - a color know to be the original royal color, a tinge of purple with deep blue hues, the color that later was also called "royal" in France (as well as Rome)? Though clothing for the Emperor stressed royal Mandarin Yellow and the French court stressed blue/white and purple, the original royal ink was indeed this ink color. The precious remnants of the original ink stones were just enough physical and documented information for the color and the characteristics of the inks, so that Noodler’s Ink could offer a sample of the Emperor’s Ink - as close a replica to that royal ink as ever offered.

Since this ink is unique and quite apart from all the other inks made, two free pens are enclosed to go with every bottle – Noodler’s Ink has tested the ink with these pens extensively and believes that they will serve you well. We recommend that you use this ink only with the enclosed two pens.

A note on the label art and ink name from Noodler’s Ink:

The ink used by the Emperor of China during the age whereby Confucius was most recognized for his greatness intrigued the ink maker of Noodler’s Ink. The quotes: ‘The weakest ink is mightier than the strongest memory.’ and ‘The four precious necessities - pen, ink, paper, and ink stone’ were also fascinating as they are attributed to Confucius.

What ink remnants and/or colors were on the ink stones of the Emperors of China? The preference was for a blue purple - a prime based purple as opposed to the more western violet/magenta and red/blue non-prime mixtures. The information has been limited and all the more so due to the distance of time and the difficulty in getting museums and collectors to cooperate in this quest. As a manner of extending gratitude and thanks for the assistance Noodler’s Ink has received, the ink is named in honor of the 77th lineal descendent of Confucius, Mr. Kung Te-cheng.

This has quickly become my very favorite ink! It's not quite blue, not quite purple, but it's definitely dark and clear. I also really like the included pen, which is easy to fill and has a nice smooth line (I'm not sure if that's due to the pen, the ink, or the combination, but whichever, it's great).

I love the color of the ink (purple-blue). The flow is great and it smells like authentic ink. It is very heavy as it bleeds through regular copy paper. Thicker paper holds up better to this ink. The fountain pen that was included has a 0.3 mm nib. This should indicate a "fine" point nib however it writes more like a medium. I love the convenience of dropper pens. I haven't had a chance to use the watercolor pen but I am excited about it.

For anyone looking for an alternative to using this ink without the pens that came with the bottle I have one for you.

I am using this ink in a Platinum Preppy 03 fountain pen using a cartridge to hold the ink. It is working very well and I don't have to be nervous about accidently unscrewing the body of the pen and dumping the ink all over the place. I use a syringe to fill the cartridge and so far I have had wonderful success with it.

I did have the cap of the Preppy pen that came with my bottle crack and that caused my pen to not be able to maintain the nib moisture level and it was extremely hard to keep writing. Since discovering the crack and swaping caps with the 2nd pen that came in the box there have been no issues and these pens write as soon as the nib touches the paper without fail.

Still LOVE this color, I hope they keep making it!

This is absolutely wonderful ink! It arrived in three days all the way across the US which was a total surprise to me. Then when I filled the included fountain pen and started using it I was once again in total shock. The ink looks vaguely purple-blue as it goes onto the paper but the dries quickly to a deep purple that has a different look than the purple with redish tinges you usually get. It dries quickly which is nice and has worked well on every type of paper I've used it on which have ranged from my journal to recycled notebook paper. I was a little skeptical about the fountain pen when I first saw it but it writes with a very nice fine line. The only thing I had to work out was getting the pen started the first few times I used it, but now a few days into using it and it starts immediately and consistently.

In short, order this ink. You won't regret it. The color is beautiful and unique. I sincerely hope that Noodler's Ink can make more of this color and that Jet Pens continues to carry Noodler's Inks the way they are now. They have the best selection of anywhere I have been able to find.

Awesome job folks..... Thank you so much.....
