||Cu*vette" (k?-w?t"), n. [F., dim. of cuve a tub.]

1. A pot, bucket, or basin, in which molten plate glass is carried from the melting pot to the casting table.

2. (Fort.) A cunette.

Cy*am"e*lide (s&isl;*ăm"&esl;*l&ibreve;d or -līd; 104), n. (Chem.) A white amorphous substance, regarded as a polymeric modification of isocyanic acid.

Cy*am"el*lone (s&isl;*ăm"&ebreve;l*lōn), n. (Chem) A complex derivative of cyanogen, regarded as an acid, and known chiefly in its salts; -- called also hydromellonic acid.

Cy"a*nate (s?"?-n?t), n. [Cf. F. cuanate. See Cyanic.] (Chem.) A salt of cyanic acid.

Ammonium cyanate (Chem.), a remarkable white crystalline substance, NH4.O.CN, which passes, on standing, to the organic compound, urea, CO.(NH2)2.

Cy`an*au"rate (s?`?n-?"r?t), n. See Aurocyanide.

Cy*a"ne*an (s?-?"n?-a]/>n), a. [Gr. kya`neos dark blue.] Having an azure color. Pennant.

Cy*an"ic (s?-?n"?k), a. [Gr. ky`anos a dark blue substance: cf. F. cyanique. Cf. Kyanite.] 1. Pertaining to, or containing, cyanogen.

2. Of or pertaining to a blue color.

Cyanic acid (Chem.), an acid, HOCN, derived from cyanogen, well known in its salts, but never isolated in the free state. -- Cyanic colors (Bot.), those colors (of flowers) having some tinge of blue; -- opposed to xanthic colors. A color of either series may pass into red or white, but not into the opposing color. Red and pure white are more common among flowers of cyanic tendency than in those of the other class.

Cy"a*nide (s?"?-n?d or -n?d; 104), n. [Cf. F. cyanide. See Cyanic.] (Chem.) A compound formed by the union of cyanogen with an element or radical.

Cy"a*nin (s?"?-n?n), n. [See Cyanic.] (Chem.) The blue coloring matter of flowers; -- called also anthokyan and anthocyanin.

Cy"a*nine (s?"?-n?n or -n?n; 104), n. (Chem.) One of a series of artificial blue or red dyes obtained from quinoline and lepidine and used in calico printing.

Cy"a*nite (-n?t), n. [See Cyanic.] (Min.) A mineral occuring in thin- bladed crystals and crystalline aggregates, of a sky-blue color. It is a silicate of aluminium. [Written also kyanite.]

Cy*an"o*gen (s?-?n"?-j?n), n. [Gr. ky`anos a dark blue substance + -gen: cf. F. cyanogŔne. So called because it produced blue dyes.] (Chem.) A colorless, inflammable, poisonous gas, C2N2, with a peach-blossom odor, so called from its tendency to form blue compounds; obtained by heating ammonium oxalate, mercuric cyanide, etc. It is obtained in combination, forming an alkaline cyanide when nitrogen or a nitrogenous compound is strongly ignited with carbon and soda or potash. It conducts itself like a member of the halogen group of elements, and shows a tendency to form complex compounds. The name is also applied to the univalent radical, CN (the half molecule of cyanogen proper), which was one of the first compound radicals recognized.

&fist; Cyanogen is found in the commercial substances, potassium cyanide, or prussiate of potash, yellow prussiate of potash, Prussian blue, Turnbull's blue, prussic acid, etc.

Cy`a*nom"e*ter (s?`?-n?m"?-t?r), n. [Gr. ky`anos a dark blue substance + -meter: cf. F. cyanomŔtre.] An instrument for measuring degress of blueness.

Cy`a*nop"a*thy (-n?p"?-th?), n. [Gr. ky`anos a dark blue substance + pa`qos affection.] (Med.) A disease in which the body is colored blue in its surface, arising usually from a malformation of the heart, which causes an imperfect arterialization of the blood; blue jaundice.

Cy*an"o*phyll (s?-?n"?-f?l), n. [Gr. ky`anos a dark blue substance + fy`llon leaf.] (Bot.) A blue coloring matter supposed by some to be one of the component parts of chlorophyll.

Cy"a*nosed (s?"?-n?st), a. [See Cyanic.] Rendered blue, as the surface of the body, from cyanosis or deficient aŰration of the blood.

||Cy`a*no"sis (s?`?-n?"s?s), n. [NL. See Cyanic.] (Med.) A condition in which, from insufficient aŰration of the blood, the surface of the body becomes blue. See Cyanopathy.

Cy*an"o*site (s?-?n"?-s?t), n. [See Cyanic.] (Min.) Native sulphate of copper. Cf. Blue vitriol, under Blue.

Cy`a*not"ic (s?`?-n?t"?k), a. (Med.) Relating to cyanosis; affected with cyanosis; as, a cyanotic patient; having the hue caused by cyanosis; as, a cyanotic skin.

Cy*an"o*type (s?-?n"?-t?p), n. [Cyanide + -type.] A photographic picture obtained by the use of a cyanide.

Cy"an"u*rate (s?-?n"?-r?t), n. (Chem.) A salt of cyanuric acid.

Cy*an"u*ret (-r?t), n. (Chem.) A cyanide. [Obs.]
