Platinum Ink




The pleasure of writing with a fountain pen is the feeling of a mild touch in writing and the beauty of the ink.


You finally found your favorite fountain pen, and this pen with your favorite ink makes you feel excited and affords much pleasure in the use of creating characters on the page.


One of the pleasures of writing with a fountain pen is that you can easily change the ink color. In changing the color of the ink or brands of the ink, please clean the nib and the feeder thoroughly to avoid ink clogging.


Please use PLATINUM ‘’Ink Cleaning kit.’’ when you change the ink.

The Ink cleaning kit is available for both for Platinum and the International cartridge of fountain pens.

With this kit, please wash the feeder and the nib of your pen with water and dry well.

“Ink Cleaning Kit” is really effective to clean the nib and the feeder especially changing the Alkaline inks and Acid inks.


Platinum Blue Back Ink      Read This!


Blue Black ink is one of our flagship products of the PLATINUM brand.


When a fountain pen was the major business tool about 50 years ago, official documents or semi-official documents like a medical chart needed mothballs because it was difficult to keep them in a good condition without them.


The Blue Black ink was developed to meet these needs.


The Blue Black ink is not a pigment but a dye ink but it remains on paper for a very long time.

Well, why does this ink last so long although it is a dye based ink ?


Many decades ago, we could not develop pigment ink for fountain pens. So we mixed ferrous tannic acid and blue dye-based ink to make ferric tannic acid, so to say “Blue Black” colored ink. I will skip boring details, but we compounded blue dyes together with ferrous tannic acid, and this Blue Black ink is became oxidized in the air after writing and become ferric. Hence, its color turns blue after writing. However, the blue dye color will gradually fades away and only the ferrous iron remains on the paper permanently.


At first, the blue color, later changed to black; that is why we call it ‘’Blue Black’’, the name comes from its function, not the color itself.

Blue Black ink has strong support from our customers because of its shading color. But, be careful ! it is acid and needs a bit attention to exchange Blue Black ink to another ink. (If you really want to change this beautiful ink to another one !)


And old fountain pens sometimes have gold plated parts around the grip section. Gold itself will not corrode itself but it may corrode by attachment with Blue Black ink.


Almost all pen makers have already discontinued Blue Black ink, but we think the truly great character of this ink will provide more and more enjoyment now that you know the character of this ink, since we explained the character and origin of this ink correctly.
