Iron gall ink strip tests, detecting iron ions, are a professional tool used in archives, libraries, and conservation studios. They allow for the rapid detection of iron ions (Fe²⁺), which can cause paper degradation and document damage.
The test is simple and safe to use – a special chemical indicator reacts, changing colour to red, which allows for immediate identification of the hazard without compromising the material's structure.
Ideal for analysing historical documents in archives, museums, libraries, and private collections.
