Diamine Ink

Diamine has been making ink since 1864 and is one of the last remaining manufacturers in the UK.  In 1925 the company created a state-of-the-art production facility in Liverpool. They have worked to maintain the original formulas, only adjusting to accommodate modern legislation.

Diamine ink is a water-based ink perfect for any brand of fountain pen. It is completely non-toxic, vegan friendly, and offers probably the widest range of quality fountain pen ink colours in the world - in both traditional and contemporary shades. Diamine is known for its vivid colors and selection of shimmer inks.

This special Registrar's Ink has long been used by registrars and clergy for filling out official documents due to its strong water and fade resistance. It is an iron gall ink, a very old form of ink made from iron salts and tannic acid. The ink is light blue when wet, but as it dries the iron in the ink quickly oxidizes and turns the ink to a dark blue-gray black.
