A big thank you goes out to The Goulet Pen Company for providing this ink for review.


Ancient Copper has been on my “Want to Try” list for a long time. This one never seemed to make it to my shopping cart for one reason or another. This, as opposed to Red Dragon, I did know why. When I first heard of Ancient Copper, there was talk on the FPGeeks forum of possible ink issues because nibs were showing up with a “crusty” substance forming all over them. Some cases were slight others seemed to be a serious case of mold. As it turns out, this was not a case of contaminated ink, but a kind of oxidation when you used the ink in pens that did not have good cap sealing properties. The pen I have been using for the last two weeks has a fairly good seal but no inner cap. The crust just started to form on the nib slit. It is a very minor case and was quickly solved with a wipe with a paper towel. I have seen some extreme cases in pictures that look downright scary. Lesson to be learned is use this ink in a pen that is fairly air tight when capped.

Ancient Copper Dry Times Are Not Bad Even on Coated Paper



As for the ink, it is a fiery red-brown that is very pleasing to the eye. I noticed that I can make the ink shade more if I print. Cursive seems to make the ink shade less and I have no idea why. HP laser paper mutes the fiery color and all shading is lost to a flat brown. The ink flows nicely but can take a bit to dry on coated papers. I noticed a dry time on Rhodia of about 15 – 20 seconds on this humid 90 F afternoon with 52% relative humidity. The color ranges from an old penny copper color to a slightly reddish yellow-brown hue that gives it the fiery look.

Overall Diamine Ancient Copper is another very pleasing ink. I know that I will be buying a bottle when this one runs out!

    Great review as usual. I have not had any issues with this ink. I generally leave a pen inked for two to three weeks and if I am going to leave the same color I do a nib flush/clean and may top off the pen depending on whether it is a piston or converter fill.

    for what it is worth


  2. Love this color and go to my bottle often. I found it in my search for what I thought I wanted was orange inks but REAL orange inks did nothing for me in the end. But I’m glad I found AC! Thanks for the review
