Cyanine dye

== Description ==
A series of dyestuffs whose chromophore is due to conjugated carbon-carbon bonds in the backbone of the molecule. This type of chromophore occurs naturally in many products, such as carotene. Cyanine dyes were first synthetsized in 1873. Also called polymethine dyes, these compounds have poor lightfastness and are rarely used on textiles. They are, however, used to make silver halide photographic plates sensitive to a greater range of light.

Cyanotype

== Description ==
A blue printed image prepared by a nonsilver process that was popular for photographs at the end of the 19th century. More recently, cyanotypes, or blueprints, were primarily used to copy architectural drawings. The cyanotype method was suggested in 1842 by British astronomer Sir John Herschel but not widely used until the 1880s after Henri Pellet developed a direct positive blueprint process (1877). In this process, cyanotype paper is coated with a ferric and an organic acid in a binder (dextrin, gum, or gelatin); after exposure to light the image is developed with potassium ferricyanide which reacts to form Prussian blue. The blue image on white paper is fixed by washing the remaining salts away in an aqueous solution.
== Synonyms and Related Terms ==
blueprint; blue print; Prussian-blue process; Pellet process; pelletones
== Risks ==
* Highly sensitive to alkalis. 
* Should not contact buffered paper.

Cyclone precipitator

== Description ==
A dust collecting device. A cyclone precipitator consists of a cylindrical chamber placed over a cone shaped funnel. Air is rapidly drawn through the cylinder forming a vortex. Centrifugal force pulls the heavier particles to the outer walls while the clean air escapes down a central tube. Cyclone precipitators are used in industry and to reduce smoke stack emissions. They are not considered effective enough for dust removal in museum use (Kuhn 1986).

Cylinder glass

== Description ==
A type of flat, window glass. Cylinder glass was formed by alternately hand blowing then swinging a globe of glass until a cylinder was formed that was approximately 5 feet long and 1 foot in diameter. The curved ends of the long cylinder were then cut off to form a tube that was split lengthwise, placed on a table and flattened with heat. Cylinder glass has a parallel wavy distortion due to thickness variations. Cylinder glass was made as early as the 17th century in Sunderland, England. It was less expensive than crown glass but, in general, of poorer quality.

Cypress

== Description ==
Any of several evergreen trees from the genus Cupressus. Many trees from related genera, like bald cypress and some cedars, also have been commonly called cypress. True cypresses are native to the Mediterranean region (Cupressus sempervirens) and the Pacific coast of North America. Mediterranean cypresses, still found in Jordan, Syria, Lebanon, Turkey, Iran, Crete, and Rhodes, were used in ancient Egypt for monumental doors, furniture, boats, statuary, coffins, boxes and carving (Gale et al 2000). Cypress wood is aromatic with a smooth, close-grain, and reddish-brown color. Currently, cypress trees are often used for landscaping effects while their wood is used for general construction, storage boxes, crates, and millwork.

DDT

== Description ==
Common abbreviation for the insecticide dichlorodiphenyltrichloroethane that was first synthesized in 1873. By 1939, Dr. Mueller discovered that the colorless, odorless crystals are toxic to insects, humans, and animals. Its successful use during World War II to combat insect carried diseases resulted in a Nobel Prize award to Dr. Mueller. In the United States, DDT was widely used as an insecticide in agriculture. Unfortunately, it was also used on many museum objects, such as plants and animals in ethnographic collections, as well as books and papers in libraries. Residues have also been found on wooden artifacts and musical instruments in museums. DDT is nonbiodegradable and its residues (DDE and DDD) may remain in or on objects for years. The breakdown of DDT may be catalyzed by some metals (aluminum, chromium, and iron) and accelerated by light and heat. It was banned for use in the U.S. in 1972.
