Review: Platinum Carbon Ink

The is the permanent waterproof black ink that Platinum has formulated for use in fountain pens.

As the Platinum Carbon Ink suggest, it does use carbon particles in its ink. The ultra-fine carbon particles are what provides the permanence, waterproof and archival features of the ink.

As with all pigmented ink, regardless of whatever nano-particles or super-nano-whatever size particles, it's recommended to clean your pen once in a while and definitely do not let the ink dry in the feed.

I like the design of the glass bottle. Looks beautiful and it has a wide opening suitable for dip pens and brushes.

It's an intensely black ink with excellent covering strength.

It's able to keep a sharp edge.

When dry, it's resistant to erasing, rubbing, smudge and water.

The ink flow is smooth, and it does not bleed over the next page.

One downside is it dries to a slight sheen at concentrated areas. This is something to note if you apply ink with brushes.


It can be use in fountain pens but be careful to clean your pens regularly since it's still pigmented.

For watercolour sketchers, it's a nice choice because the ink is waterproof and you can layer watercolour over it.

For writers, the ink is dark and doesn't bleed.

This is one of the more expensive ink I've used. It's usually selling around US $20 for a 60ml bottle. I suppose it's still alright if you're going to use the ink for long period of time. However, for comic inking, there are other more economic choices.

The other comparable ink to the Platinum Carbon Ink is the Sailor Kiwa-Guro Nano Ink.


Not sure why but on the Leda Art Supply sketchbook, Platinum Carbon Ink features but not the Sailor Kiwa Guro

Hi Teoh,

Hi Teoh,
First of all thanks for your gave me so much info!!! And I love your demo's on youtube.
My question is about the amount (...)of fountainpens I have, a few Lamy Safari's, some Preppy's and a Sailor. And I also have different bottles with coloured ink (Platinum Carbon and De Atramentis). You said above: definitely do not let the ink dry in the feed. So what if I want to use another colour...Is it possible to store a filled converter so I can use another (with another colour) filled converter...Or do I have to finish the ink in the first converter before using another colour? I really love the different colours and love to draw with them all...I would prefer to use all these colours and fill all my different pens with different colours.
I am curious to know how this works for you.

Thanks for your quick reply

Thanks for your quick reply Teoh, but my question was not about mixing inks it was about storing a full converter. Sorry that I didn't make myself clear enough, english is not my native language.
