Spotting of the paper, usually brown or yellowish brown, caused by a chemical reaction. This is usually seen in 19th century books.
Light tan or brown spots usually caused by the ageing of a book's paper or binding over time. Foxing is often more severe in books housed in humid climates.
Brown or tan blotches commonly seen on antique book pages. While initially caused by chemical impurities in the paper foxing is always aggravated by poor and careless storage.
Discolouration of paper, usually in the form of random rust-coloured spots. Believed to be caused by one or more of the following: fungus or mould, impurities in manufacture, high humidity or dampness, and airborne acids. The removal of foxing is generally not recommended as the treatment methods used usually result in weakening of the paper.
Reddish brown patches found on artwork that was not framed using conservation materials. This is caused by a combination of metallic salts, high humidity and high temperatures.
A discoloration of the paper in a book, consisting of light brown spots caused by iron deposits or fungus. May occur in anything less than the highest quality paper, and thus does not necessarily diminish the value of the book.
Brown or pale patches of discoloration or stains on a sheet of paper. Foxing is caused either by impurities in the paper or by molds. It can be treated with conservation methods.
A patchy discoloration found in the paper of old books. It can range from barely visible to ruinous.
The development of patterns of brown or yellow splotches (stains) on old paper. Caused by a type of mold, foxing is often removed by treating with diluted bleach.
The brown stain marks under the celluloid covering of a button usually caused by water or excessive moisture rusting the metal disc under the paper.
Mold growth on paper artwork (typically appearing as brown spots). Foxing is found particularly on old prints and graphics, maps, letters and other documents.
rust colored spots which occur on paper resulting from oxidation processes apparently caused by certain mold fungi.
This term applies to the orange discoloration that appears on antique books and prints. It is caused by a fungus encouraged by storage of the affected article in damp poorly ventilated conditions.
Yellowish-brown aging stains sometimes found on older paper money. This reduces the value of the note.
Small brown spots that may appear over time on paper
Yellow to brownish spots (a mold) which can appear over time on paper, caused by impurities in the paper reacting with atmospheric conditions, particularly humidity, and exacerbated by non-conservation framing. Often easy to restore.
the small brown spots which develop on older paper photographs, particularly albumen prints, probably caused by chemical instabilities in the paper.
Small spots of mildew that can form on old prints and drawings.
A term used to describe brown color spots on paper; these are caused by trapped moisture.
Spotting (usually dark) on documents. Damage caused by mold.
A descriptive term used for scattered spots commonly reddish-brown in color, but also applied to spots of other coloration ranging from yellow to black, found in paper sheets. Despite 60 years of research there remains uncertainty as to the cause. It may be fungal, from metal debris left in the paper stock during the papermaking process, from the interaction of moisture and cellulose, or may be due to multiple causes.

This a print condition of scattered brown spots usually a result of too much bleach used to manufacture the paper which reacts chemically with dampness.
The small orange and brown spots found on the pages and coversof comics.
Brownish-yellow spots or stains, or other discoloration on paper, a form of fungal growth caused by damp.
the brown spots that form on paper.
Small spots that appear on paper; a sign of deterioration.
is a reddish-brown spotted area on a print, paper, book, or canvas. The foxing is really a fungus and if caught early can be stopped or removed.
Yellow spots on the paper's surface. These are spots of mildew, penetrating the paper which cannot be removed by erasing but may occasionally be removed by bleaching.
yellow-brown aging stains on the paper.
The brown age spots thought to be caused by impurities in paper (e.g.: acid, exposure to humidity, etc.)
rust-colored spots caused by impurities in paper when exposed to certain humidity and temperature factors. The process of foxing is inherent to the particular paper used in each book; foxing will never appear on some books.
A fungi that attacks paper and leaves a tell tale red-brown dust spot.
reddish-brown (fox coloured) spotting.
Defect caused by mold growth which results in a spotting effect usually at the edges of comic books.
Small, usually brown, spots on the paper caused by mold. Foxing often results from storage in damp conditions. GORE A section of a globe printed on paper, intended to be cut out and pasted to the surface of a sphere. Gores are usually shaped like an American football.
damage caused to paper by oxidation of metallic substances either intrinsic to the paper or (in the case of pinback buttons) by oxidation of the metal behind the paper; appears as brown spots or streaks
Tiny orange-brown that appear on the cover and/or interior pages of a comic book that is caused by mold.
Spots, usually brown, which are caused by mould, result from storage under damp conditions. Exposure to dust, and soiling from poor handling, also contribute to foxing.
Brown or grey-brown spotting on paper produced by a mould.
rust colored spots which occur on paper as a result of the oxidation of both organic and iron impurities in the paper under certain humidity and temperature conditions.
This may be considered sort of the paper money hobby's equivalent to toning on a coin, except that the yellow-brown stains of varying intensity which are foxing are generally undesireable, whereas toning on a coin may be desireable, depending on who you talk to. Generally considered a minor defect unless its a really noticeable stain.
A pattern of spotting or speckling on paper or sometimes cloth, usually brown or yellowish brown in tone and often more or less circular in shape.
Foxing occurs when brownish spots on paper artefacts appear due to mould growth or the presence of metal residue in the paper.
Spots of discoloration on paper.
Discolouration on paper, generally in the form of random rust coloured spots. Believed to be caused by one or more of the following; fungus or mould, impurities in manufacture, high humidity or dampness, airborne acids. The removal of foxing is not generally recommended in library preservation since methods of removing foxing almost always will cause further damage to the object.
Fungal spots or stains on prints caused by excess humidity. Many of these unfortunate marks are rust colored and sometimes are from the iron contained in the paper itself.
small brown stain spots on card mount (a fungus that can often be removed/reduced;
Brown spotting of the paper caused by a chemical reaction, generally found in 19th century books, particularly in steel engravings of the period.
Brown spots in paper due to chemical reactions of impurities naturally present in the paper with atmospheric oxygen, or due to fungal attack. Light foxing is quite characteristic of old imprints, and is not considered a defect unless it detracts from eye appeal or legibility. Foxing is especially common in old newspapers, which were almost invariably printed on the cheapest obtainable grades of paper

Orange brown spotting caused by a reaction of the decay in the paper with normal moisture. A defect of note in plates especially.
The brown stains appearing on the paper. Formed when excessive humidity or moisture is present. Also due to the poor quality of the paper and the chemicals used in the production.
