Diamine - Registrar's Blue-Black (30ml.)

Wishlist: (0)

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. 

Note: This ink is safe to use in fountain pens, but we recommend cleaning your pen regularly due to the above-average acidity of iron gall inks.
