Cassia

== Description ==
An aromatic bark and oil obtained from the Cinnamomum cassia tree, native to China and southeast Asia. Cassia bark contains from 1 to 2 percent volatile oil, the principal component of which is cinnamic aldehyde. Small amounts of cassia oil were sometimes added to varnishes and resin as a plasticizer. Cassia oil is used as a cinnamon flavoring in candy, chocolates, and liqueurs. In classical times, oils with similar spicy smells from the African camphor tree (Ocotea usumarensis) native to east Africa were used in ancient Egypt (Serpico and White 2000). 
See also cinnamon oil.

Cassiterite

== Description ==
A hard, dense, brown to black mineral composed of Tin dioxide. Cassiterite is the principal ore of tin. Starting in the 15th century, cassiterite was mined in Saxony and Bohemia. Currently it is mined in southeast Asia (Myanmar, Thailand, Malaysia, Indonesia), Bolivia (Llallagua), Nigeria, Russia, England (Cornwall), and the U.S. (Virginia, Washington, California).

Cast iron

== Description ==
An alloy of iron with carbon that is hard, brittle and nonmalleable. Cast iron contains about 2 to 4% carbon and 1 to 3% silicon. It was made in China by at least the 3rd century BCE. The technique for its production did not reach Europe until medieval times. Cast iron is manufactured by melting scrap iron or pig iron in a cupola that is in contact with the coal fuel, then casting the molten iron into a mold. It is inexpensive and easy to make. In the 1830s, cast iron was used for structural and decorative building components in North America. It was also used for cast iron pipe, stove pipe, firebacks, cauldrons, and cannons. 
See also gray cast iron, and white cast iron.
== Synonyms and Related Terms ==
grey cast iron; gray cast iron; Gusseisen (Deut.); fonte (Fr.); gietijzer (Ned.); gjutjärn (Sven.); hierro fundido (Esp.); ferro fundido (Port.)
==Physical and Chemical Properties==
* Gray cast iron (with silicon) has less tensile strength and shock resistance than steel. It is difficult to weld. 
* The seasoning or impregnation of cast iron cookware with oil minimizes rusting.

Cast stone

== Description ==
A precast building stone prepared from several formulations that harden to a rocklike solid. Examples of some cast stone binders are: clay (Coade's stone), plaster (Protean stone), water glass (Siliceous Concrete Stone), oxychloride cement (casting stone), Keene's cement (marezzo marble); [[Epoxy|epoxy], and portland cement (Frear stone, Victoria stone, Benedict stone). Cast stones were used extensively in the late nineteenth and early twentieth centuries. They often incorporated fine and coarse aggregates for texture along with pigments or dyes to imitate coloring and veining of natural stones. Cast stones were produced in many sizes and shapes, often with intricate patterns and tracery.

Cat's eye

== Description ==
A semiprecious gemstone composed of quartz that contains a band of parallel fibers. When cut and polished as a cabochon, the band produces an opalescent light reflection that appears to move across the convex polished surface of the stone as it is rotated. This effect is called chatoyancy. Cat's eyes are usually a pale yellow or greenish color. A dark golden yellow cat's eye from South Africa is known as a tiger's eye or African cat's eye. It is a quartz stone with oriented fibers of crocicolite. True cat's eye is a variety of quartz, but other stones can also show this effect, such as chrysoberyl (oriental cat's eye), chalcedony, tourmaline, scapolite, cordierite, orthoclase, albite, willimanite and beryl. Corundum has an imperfect chatoyancy which produces a star effect rather than a line.

Catalin

== Description ==
[American Catalin Corporation] A trademark for cast phenolic resin products produce from the early 1930s to the mid 1940s. In 1926, the Catalin chemists developed a clear formulation for phenolic resins that could be cast into shapes. Using synthetic dyes, Catalin products were produced in 15 colors and since no fillers were used the pieces were semi-transparent. These colorful pieces were used for jewelry, radios, desk sets, and novelties. They were in distinct contrast to the dark, opaque, Bakelite products that were used mostly for utilitarian pieces. Catalin objects shrank approximately 4-5 % within a few years of production resulting in numerous cracks. The resins also yellow significantly when exposed to ultraviolet light.
