Foxing and Papers

Foxing is an age-related process of deterioration that causes spots and browning on old paper documents such as books, postage stamps and certificates. I investigated the cause of foxing stains on ancient Chinese papers at the Museum of Shanghai History and identified the relevant fungi species for the purpose of paper document preservation. It was a treasured experience to be in touch with our ancient papers hand made hundreds of years ago.
