It is made from a combination of gallo-tannic acid extracted from oak galls (small growths on oak trees caused by wasp larvae) and iron sulphate. The ink is initially pale when applied to paper but darkens to a deep, rich black or dark brown as it oxidizes.\u003c\/p\u003e\n\u003cp\u003eThis ink was favoured for centuries because of its permanence and resistance to fading, making it a popular choice for official documents, manuscripts, and artworks.
