Lignin is a natural substance found in paper and books that causes them to turn yellow and become brittle over time. It's like the glue that holds wood fibers together, but it can be damaging to historical documents. In manuscript restoration, professionals often need to deal with lignin-related damage or work with lignin-free materials to preserve important documents. Understanding lignin is crucial because it helps conservators choose the right preservation methods and materials for their work.
Specialized in removing lignin damage from historical documents using advanced conservation techniques
