False color representation of a SHG microscopy

Caption

False color representation of a SHG microscopy image of a 4,000-year-old bundle of flax fibers originating from a textile on the surface of a vase from the ancient city of Tello in Mesopotamia. The authors found that cellulose macrofibrils (green) were exceptionally preserved in place with the corrosion of the copper object, in a mechanism that combined mineralization and sol-gel silicification.
