Plenty of medieval iron gall writings have fared much better, however, and modern iron gall inks are far gentler than their medieval forebears. If you open a medieval book written in iron gall ink, you may find pages filled with letter-shaped holes as if the letters were cut out of the page with a laser. So if iron gall inks are so great, why don’t we see more of them around? The main reason is that they’re acidic. ![]() In addition to being waterproof, iron gall inks tend to be dry-writing and very well-behaved, making them a good choice when using wetter pens or less fountain pen friendly paper. The dyes used to color the ink may run or fade when wet, but the dark gray lines that the iron gall particles make will remain sharp and clear. A typical iron gall ink like Diamine Registrar’s Ink will start off as a light blue when wet and transform within minutes into a dark blue black. To make them easier to see when wet and more appealing to read when dry, iron gall inks are mixed with dyes to give them color. Pure iron gall ink is clear when wet and turns dark gray over several minutes as it dries and oxidizes. These inks were traditionally made by mixing iron salt crystals with tannic acid from oak galls 2-hence the name “iron gall.” Like pigment inks, iron gall inks are made of insoluble particles that become highly water resistant once embedded in paper. All writing samples were allowed to dry for at least 24 hours before testing to achieve maximum water resistance.Ī historical ink dating back at least as far as the Roman Empire, iron gall inks were a staple in the western world into the early 20th century. Each ink’s waterproofness score is based on the test it performed worst in. It can also reveal the various component colors the ink is made up of. This test shows how prone to smearing from a wet finger or brush the ink is. Brush tests were done with a Kuretake medium water brush. This test shows how much the ink will run or fade when left soaking in water. Soak tests were performed by dipping writing samples in water for 30 seconds. Tests were done using Rhodia DotPad paper and a TWSBI ECO 1.1 mm fountain pen dipped in ink. At least you may get to reuse the same sheet of paper once it dries. Your work will be gone, and there might not even be a trace you wrote anything at all. Some of your writing may survive, but don't count on it. Not everything you wrote will survive, but hopefully enough will be left for you to reconstruct the rest from context. You may still want to write a fresh copy, though. The ink may smudge a bit, but none of what you wrote will be lost. Just let the paper dry off and you can still hand it in. What will happen if your homework gets wet?
