Description

Diamine has been producing fountain pen ink in Liverpool, England since 1864. Their inks are made with a
gentle formula and are known for consistent, well-behaved flow across all fountain pen brands. The
Registrars Ink is one of the most historically significant inks in the range – a formula with roots going back
centuries, still in production because nothing has improved on what it does.

The colour shift is one of iron gall ink’s most distinctive characteristics. When it first touches the page it is a
medium, slightly translucent blue. Over the following minutes and hours, the iron in the ink reacts with oxygen
in the air – a process called oxidation – and the colour deepens progressively into a dark blue-black.

The rule is simple: clean your pen regularly. Do not leave Registrars Ink sitting in a fountain pen for weeks without use. Flush the pen with water between ink sessions and always clean thoroughly before storing. With regular maintenance it is safe for use in modern fountain pens with
stainless steel or gold nibs.

For professional use, the case for Registrars Ink is straightforward: documents signed with conventional dye
inks can fade significantly within decades. Documents signed with iron gall ink remain legible and unaltered
for centuries. South African legal and ecclesiastical contexts where permanent, archival documentation is
required will find this ink well suited to the purpose.

For everyday use, it is a deeply satisfying ink to write with. The flow is on the drier side compared to modern
lubricated inks, which reduces feathering on lower-quality paper and gives it excellent performance across a
wide range of paper types. The medium shading gives written text visible tonal variation – thin strokes lighter,
broader strokes darker – that adds character and life to handwriting.

Perfect For:
• Legal professionals, registrars, and clergy requiring archival-quality ink.
• Fountain pen users who want a permanent, water-resistant everyday ink.
• Contract signing, official correspondence, and important documents.
• Writers and journalers who want their work to last.
• Anyone who appreciates the character and history of iron gall ink.
• Gift for fountain pen enthusiasts.
