What is Foxing?
Foxing refers to the age-related process of deterioration that causes splotches, flecks and browning on old paper such as stamps, books and certificates. These reddish-brown spots or stains can ruin the appeal of your original piece or document and cause serious damage if left untreated.
Causes of Foxing
There are different theories behind the idea of foxing. One is that foxing is caused by a fungal growth on the paper. Another theory is exposure to moisture and humidity. A third theory is that foxing is caused by the effect of certain papers of the oxidation of iron, copper or other substances in the pulp or rag from which the paper was made.
A conservator applies various conservation-approved chemicals to your document to help lighten the stains and reduce the acidity in the paper. These methods, however, carry the risk of side effects or damage to the ink or paper.
