Webster's 1828 Dictionary

FLUOR

n.[Low L. from fluo, to flow. ] 1. A fluid state.
2. Menstrual flux. [Little used in either sense. ]
3. In mineralogy, fluate of lime. Fluor spar is the foliated fluate of lime. This mineral, though sometimes massive, is almost always regularly crystallized. Its crystals present most frequently the form of a cube, often perfect, sometimes truncated on all its edges by planes, which form with the sides of the cube an angle of 135 degrees. The colors are very numerous and beautiful.
The flutate of lime, fluor, was so named from its use as a flux for certain ores.

 

FLUOR-ACID

n.The acid of fluor.

 

FLUORATED

a.Combined with fluoric acid.

 

FLUORIC

a.Pertaining to fluor; obtained from fluor; as fluoric acid.

 

FLUORIN, FLUORINE

n.The supposed basis of fluoric acid.

 

FLUOROUS

a.The fluorous acid is the acid of fluor in its first degree of oxygenation.

 

Webster's 1913 Dictionary

FLUOR

Flu "or, n. Etym: [L., a flowing, fr. fluere to flow. See Fluent. ]

 

1. A fluid state. [Obs. ] Sir I. Newton.

 

2. Menstrual flux; catamenia; menses. [Obs. ]

 

3. (Min. )

 

Defn: See Fluorite.

FLUORENE

FLUORENE Flu `or *ene, n. (Chem. )

 

Defn: A colorless, crystalline hydrocarbon, C13H1 having a beautiful violet fluorescence; whence its name. It occurs in the higher boiling products of coal tar, and is obtained artificially.

 

FLUORESCEIN

FLUORESCEIN Flu `o *res "ce *in, n. (Chem. )

 

Defn: A yellowish red, crystalline substance, C2 H12O5, produced by heating together phthalic anhydride and resorcin; -- so called, from the very brilliant yellowish green fluorescence of its alkaline solutions. It has acid properties, and its salts of the alkalies are known to the trade under the name of uranin.

 

FLUORESCENCE

Flu `o *res "cence, n. Etym: [From Fluor. ] (Opt. )

 

Defn: That property which some transparent bodies have of producing at their surface, or within their substance, light different in color from the mass of the material, as when green crystals of fluor spar afford blue reflections. It is due not to the difference in the color of a distinct surface layer, but to the power which the substance has of modifying the light incident upon it. The light emitted by fluorescent substances is in general of lower refrangibility than the incident light. Stockes.

 

FLUORESCENT

FLUORESCENT Flu `o *res "cent, a.

 

Defn: Having the property of fluorescence.

 

FLUORESCIN

FLUORESCIN Flu `o *res "cin, n. (Chem. )

Defn: A non-metallic, gaseous element, strongly acid or negative, or associated with chlorine, bromine, and iodine, in the halogen group of which it is the first member. It always occurs combined, is very active chemically, and possesses such an avidity for most elements, and silicon especially, that it can neither be prepared nor kept in glass vessels. If set free it immediately attacks the containing material, so that it was not isolated until 1886. It is a pungent, corrosive, colorless gas. Symbol F. Atomic weight 19.

 

Note: Fluorine unites with hydrogen to form hydrofluoric acid, which is the agent employed in etching glass. It occurs naturally, principally combined as calcium fluoride in fluorite, and as a double fluoride of aluminium and sodium in cryolite.

Defn: Calcium fluoride, a mineral of many different colors, white, yellow, purple, green, red, etc. , often very beautiful, crystallizing commonly in cubes with perfect octahedral cleavage; also massive.
