What does guncotton mean?
Guncotton is a mass noun denoting a highly explosive form of nitrocellulose, a material made by chemically modifying cotton cellulose. Historically, guncotton served in military propellants and in blasting, and its importance grew during the nineteenth century as chemists developed ways of working with nitrated cellulose. In modern writing the word is mainly historical or technical; it is not interchangeable with all forms of nitrocellulose, since the latter also names non-explosive industrial materials used in lacquers, films, and plastics. The compound is also significant in the history of chemistry: closely related nitrocellulose helped make celluloid, one of the first successful plastics, and later supplied early photographic film. Contemporary references therefore connect guncotton both with the destructive power of modern propellants and with the development of materials science. The word is normally used as an uncountable substance name, though rare plural forms occur when separate quantities or samples are discussed. Its unusual history makes it useful to readers interested in military technology, industrial chemistry, or the surprising overlap between ordinary plant fibre and early plastics.
nounA highly explosive form of nitrocellulose made from chemically treated cotton, used historically in military propellants and as a blasting material.
- A highly explosive nitrocellulose material made from chemically treated cotton, used historically as a military propellant and blasting explosive.
"The nineteenth-century factory produced guncotton for use in military propellants."
"The nineteenth-century factory produced guncotton for use in military propellants."
"The museum label explained that guncotton is nitrocellulose made from chemically treated cotton."
Rare; guncotton is normally uncountable. The plural is used when separate quantities, batches, or samples are discussed.
"The archive identifies these two guncottons as samples from different factories."
Gun-cotton's chemical relative nitrocellulose also helped launch celluloid and motion pictures: one transformation produced explosives, while another helped create plastics and film.

Where does guncotton come from?
The English compound dates from the mid-19th century and combines gun with cotton. The second element names the cellulose-rich plant fibre that was chemically modified, while gun refers to the material's military use. Because the name is a transparent compound, its closest relationships are the two component words and their derivatives—cottonseed, for example, and gunner—rather than separate Latin or Greek cognates.
How guncotton is actually used
Chiefly historical or specialized. It is normally an uncountable mass noun, although the older two-word spelling “gun-cotton” is also encountered.
