Fountain pen ink bottles

Fountain pen ink bottles: a spectrum of colors, classic brands, and storage tips for writers and calligraphers.

About this subject

Fountain pen ink bottles are containers that store liquid inks specifically formulated for fountain pens. Unlike cartridges, bottled inks offer a wider range of colors and brands, and are more cost-effective in the long run. Classic brands like Pelikan, Waterman, Parker, and Montblanc provide standard lines, while artisan manufacturers such as Diamine, Noodler's, and J. Herbin produce hundreds of options with unique properties like shimmer and sheen.

Ink composition varies between dye-based and pigment-based. Dye inks are more fluid and easier to clean but may fade under UV light. Pigmented inks are more resistant to water and light but require more careful pen maintenance to prevent clogging. pH levels also matter: most inks are slightly acidic to avoid damaging pen components, but very low pH can corrode metals.

In the global market, fountain pen ink has seen a resurgence among calligraphers and handwriting enthusiasts. Specialty retailers in cities like London, Tokyo, and New York import niche brands, while small-batch producers experiment with colors and formulas. The practice of filling pens from bottles, known as "filling," is cherished by aficionados for its ritualistic and customizable experience.

A fun fact: the typical bottle shape, with a wide mouth and rectangular base, allows the pen nib to be immersed even when the ink level is low. Some bottles feature an internal reservoir or a slanted cap to assist in filling. To prevent evaporation, bottles should be closed immediately after use and stored in a cool, dark place.

Frequently Asked Questions

What is the difference between dye-based and pigment-based fountain pen ink?

Dye-based inks use colorants dissolved in water, are more fluid and easier to clean, but may fade under prolonged sunlight. Pigment-based inks contain fine suspended particles, offering greater water and light resistance, but require more frequent maintenance to prevent clogging.

How should fountain pen ink bottles be stored?

Keep bottles tightly closed in a cool, dark place away from direct sunlight and temperature fluctuations. Avoid leaving them open for long periods to prevent water evaporation and dust contamination.

Can I mix inks from different brands?

It is possible but not recommended, as each manufacturer uses distinct formulations that may react unpredictably, causing coagulation or clogging. If you want to experiment, mix small amounts and test before using in your pen.
