cork (pigment)

A type of dye ranging from purple to red in color, obtained from certain lichens growing, for example, on rocks in Scotland and the north of England.


corkboard

The projecting, uppermost features of classical entablatures; use also for similar features crowning a window or wall.


Cornus (genus)

Genus of 30-50 species of shrubs, trees, and herbs native to Europe, eastern Asia, and North America.

cotton (textile)

Textile made from cotton fiber.


cottonwood (wood)

General term for wood from several species of poplar trees, all having in common that they have a soft, pale color, are fine-grained with uniform texture, may be worked easily, stain well, but have a tendency to warp. Cottonwood is used for millwork, musical instruments, paneling, packing boxes, paper pulp, and excelsior (wood shavings used for stuffing).


coursed ashlar

Building material comprising squared stonework laid in regular courses of consistent height; though each course may vary in height.


cover tile

The tiles that bridge the open joint between rows of tiles in a roof. For example, in ancient Greek architecture, the roof tile (imbrex) of terracotta or marble, usually semicircular (Laconian) or triangular (Corinthian) in section, bridged the open joint between two rows of flat tiles or pantiles (tegulae).


creosote

A coal-tar distillate that is a mixture of organic compounds, largely hydrocarbons, commonly used as a wood preservative.


crown glass

Flat pane glass made by blowing a bubble of glass, transferring it from a blow-pipe to a rod, cutting it open, then rapidly rotating it until, by centrifugal force, it is spread into a flat disk. Can be either small individual panes with so-called bulls-eyes in the centers or large disks that are annealed and cut into pieces. Crown glass is thin and brilliant with a slight convexity and concentric wavy lines. Known to the ancient Romans throughout the Empire; found in windows of medieval cathedrals.


crushed stone

Rock, often granite, limestone, or trap rock, that is quarried, crushed, and graded and then used for making concrete, railway ballast, and road making.


Cryptomeria japonica (species)

Species of conifer native to Japan; the only species in its genus.


crystal (lead glass)

Fine, high quality, heavy, decorative glass made with fine white sand, at least 24% lead oxide, and small amounts of potash and niter. It is clear, colorless, highly refractive glass that is heavy and has greater than twice the density of standard borate glass. It was developed in England in 1676; often used for high quality chandelier prisms and fine stemware.


crystal (material by form)

curtain walls (nonbearing walls)

Nonbearing walls supported by the members of a rigid frame structure, such as a reinforced concrete or steel frame, and therefore serving to enclose but not to support. Nonbearing walls supported by the members of a rigid frame structure, such as a reinforced concrete or steel frame, and therefore serving to enclose but not to support.


cut glass

Glassware with facets, grooves, and depressions produced by cutting with a rotating wheel of metal or stone.


cut nails

Nails having sharp edges along four sides of the shank, and often a flat, rectangular point. The shape of the shank allows the nail to punch its way through timber fibers rather than causing the wood to split. An example of use is for nailing hardwoods, such as oak flooring.


cut velvet

Velvet in which the loops formed by the pile warp are cut to form tufts.


cyclopean concrete

Mass concrete in which large stones, each weighing 100 lb. (45.4 kg) or more, are embedded when the concrete is laid. The stones, called pudding stones or plums, are typically less than 6 in. (15 cm) apart and farther than 8 in. (20 cm) away from any exposed surface.


cypress (wood)

Wood of trees of the Cupressus genus, native to Asia, Africa, Europe, and the Americas, and known for its durability.
