Bottled ink is one of the joys conferred by fountain pen ownership. An enormous range of colours are available (we have over 400 colours available and you can even mix your own); it can be economical and eco-friendly; and there's some satisfaction in the process of filling a pen.

It can of course be inconvenient at times, but the sheer variety of ink on sale in the 21st century is a testament to the ongoing popularity of bottled ink and the affection in which it is held.

Any fountain pen can use any reputable brand of ink - despite what pen manufacturers and their vested interests might imply. It's true that there are some pens that are more fussy about ink than others, and there is quite a wide variation in the viscosity and colour of the various brands, but in general the choice of ink will normally come down to personal preference or cost.

However, two brands which stand out in most often in polls of fountain pen users are Waterman Ink and Diamine Ink, and we heartily recommend these to any fountain pen owner. Diamine in particular offers an enormous range of colours and it's still manufactured right here in the UK. We love their inks so much that we've had them make a small range of extra colours especially for us - see our Cult Pens Deep Dark Inks.

Fountain pen ink is not generally very waterproof - the properties that make ink waterproof are not friendly to delicate fountain pen innards. However, Platinum's Carbon Ink is about as safe as it gets and is thoroughly waterproof. You'll need to rinse out your pen before storage though. Graf von Faber-Castell's line of luxury ink is safe for any pen, and boasts impressive if not bullet-proof tolerance to water.

Finally, if you fancy creating your own unique ink colour, try Platinum's Mix-Free Ink - colours specifically designed to blend with each other.

Fountain Pen Ink FAQ

What inks are safe for fountain pens?

Anything sold as 'fountain pen ink' should be fine. But some are safer than others. Specialist inks containing very finely ground pigments, inks made to sheen, and inks with shimmering particles, can all add a bit of risk. While these should be perfectly ok to use in fountain pens, they’re probably best avoided in a pen that’s especially valuable to you.

What is 'sheening' ink?

Sheening inks have very high concentrations of dye, of particular types, which will leave extra dye on the surface, refracting the light in interesting ways - usually layering a different colour where the ink goes down thickest. The effect can vary hugely with the paper used - some paper will absorb the ink quickly, leaving nothing to sheen; other paper will let the ink dry onto the surface, sheening different colours in the light.

The concentrated dye makes these inks a bit higher risk, so it's best not to leave them in an unused pen for long, and they may take a bit more flushing out than usual when cleaning your pens.

What is 'shimmering' ink?

Shimmering inks use very finely-ground particles, usually of gold or silver metal, giving an effect like very fine glitter, so your writing or drawing catches the light and sparkles. While we generally find them safe to use in fountain pens, a bit of extra care should be taken not to let these inks dry in the pen, as the particles could then clog the feed.

Can I use drawing ink in a fountain pen?

In general, no - drawing inks contain pigments that would clog the feed. There are drawing inks made for fountain pens, like Platinum Carbon Black, which can be used, but a bit of extra care would still be recommended.

Can I use calligraphy ink in a fountain pen?

Only if it’s intended for fountain pens. Most calligraphy ink is made for dip pens, and is not safe in fountain pens. They are usually pigmented, and some contain shellac to give extra shine, which would be very bad in a fountain pen!

Are there permanent fountain pen inks?

Any permanent ink will take a bit of extra care, and only use ones specifically made for fountain pens. Platinum Carbon Black is a good choice.

FAQs

Which is better fountain pen or ink pen? ›

The first major difference is in the ink. Ballpoints use a thicker ink that lasts much longer over time, this can lead to a scratchy writing experience, however. Fountain pens use a liquid-based ink which doesn't dry as quickly and allows for the pen to flow more smoothly.

What type of ink is best for fountain pens? ›

Pilot Iroshizuku ink is among the best fountain pen inks for everyday use that can be found today. This ink is worth every penny when you take into consideration the quality and quantity of ink you get.

Why are fountain pens not used anymore? ›

They were invented in the 1880s and became popular in the 1920s up to the 1950s. However, their popularity dipped when the more affordable and convenient ballpoint pens took over. After all, back then, fountain pens were messy to use and inconvenient.

Can you use any fountain pen ink in any fountain pen? ›

While many pen manufacturers make pens that will take standard international size ink cartridges, some do not design their pens this way. Other popular fountain pen brands require what is called a proprietary ink cartridge. This means that the fountain pen model requires ink cartridges that are from the same brand.

Why are fountain pens so expensive? ›

Many fountain pens are produced using machines, but some models are made by hand. This makes the pen more valuable and, thus, more expensive. Some people look for the value that expert craftsmanship adds to a handmade fountain pen.

Why are fountain pens not popular? ›

Popular from the 1920s through the 1950s, they were first developed in the 1880s. Although once widely used, their use has declined due to the widespread availability of cheaper and more practical ballpoint pens. After all, fountain pens were unwieldy and inconvenient to use back then.

Why is it not advisable to use a fountain pen? ›

One of the drawbacks is that they have the potential to be quite filthy, and another is that the ink often bleeds through paper that is too thin. Let's take a more in-depth look at the drawbacks so you can choose whether or not a fountain pen is the correct choice for you.

Why can't I write with my fountain pen? ›

Sometimes, ink can harden in the nib reservoir, making it difficult for wet ink to flow through the feed. To remedy this, give the nib of the dried fountain pen a thorough clean. Dip a stiff paintbrush into warm water mixed with washing up liquid and use the bristles to scrub residue off the nib.

What ink to avoid in a fountain pen? ›

* With such pens, be very conservative in your choice of inks – stick to brands such as Waterman, Parker, Sheaffer, and Pelikan, avoiding reds and purples and browns. If you use a highly pigmented ink in such a pen, staining is likely, and it may not be reversible.

Can you just dip a fountain pen in ink? ›

You can take any fountain pen you have, dip the nib into an ink bottle (make sure it's clean!), and then write like you would normally. In fact, this is how many people try new fountain pens for the first time. However, the capillary action of the nib and feed will only soak up enough ink for a few sentences.

What is the smoothest writing fountain pen? ›

Here are some of the best smooth writing fountain pens that you can try.
  • Pelikan M205. Pelikan is known for manufacturing some of the smoothest and most consistent nibs in the fountain pen world, and the M205 is no exception. ...
  • Pilot Vanishing Point Decimo. ...
  • LAMY 2000. ...
  • Pilot Custom Urushi.

Are fountain pens actually better? ›

Smooth writing experience: Fountain pens use liquid ink, which flows smoothly onto the paper. This makes writing with a fountain pen feel effortless compared to ballpoint or gel pens that use dry ink & require more pressure on the paper. The result is a more comfortable and enjoyable writing experience.

Do you write better with a fountain pen? ›

With a little practice, most fountain pen users also believe their handwriting improves. The smooth flow of ink on paper is freeing, making a more natural connection to the art of writing. Over time, the pen adapts to your writing style, making it much more personal than any other writing instrument.

Which category of pen is best? ›

Liquid inks like Fountain Pens and Rollerballs are better for longer writing. Oil-based or gel inks like Ballpoints and Gel pens are ideal for periodic writing and writing on the go.

Which is better, a fountain pen or a gel pen? ›

With that said, I wonder how many other fountain pen folks would agree with me that in terms of true usability, roller gel pens are hard to beat for sheer writing pleasure. They are incredibly smooth on far more types of paper than any fountain pen I own.
