Foxing is an age-related deterioration process that causes spots and browning on old paper documents such as books, stamps, and certificates. Paper that has been affected is said to be “foxed.” Although unsightly, foxing has no effect on the paper’s integrity.
Causes of foxing
The causes of foxing are unknown; one theory is that it is caused by a fungal growth on the paper, but it is possible that multiple factors are involved. High humidity, as well as the oxidation of metals and other substances in pulp or rag, could all contribute to foxing.
Repairing foxed documents
Each method has its own set of advantages and disadvantages for protecting text and images, including the risk of side effects or damage to the paper or ink.
In biological specimens
It is generally not advisable to repair study specimens, except in the case of mechanical damage, and type specimens should not be altered in any way. If foxing affects the study value of a specimen, this should be noted on the specimen label. Color standards can be used to document coloration before or during the early stages of foxing.
It can also be used to intentionally scuff items of clothing to make them appear older and more expensive.
