Tellurium

== Description ==
A nonmetallic element that is similar to selenium. Tellurium was first identified in 1782 by Franz von Reichenstein, but it was later isolated and named by Martin Klaproth in 1798. Tellurium has an estimated abundance in the earth's crust of 0.002 ppm. Tellurium usually occurs as telluride in gold, silver, copper, lead and nickel ores. It is mined in Colorado, California, Ontario, Mexico and Germany. Tellurium is a silvery-white solid. It is used as a colorant in glass and ceramic glazes and to make a black finish on silver. Small amounts improve the machinability of steels and copper alloys. Tellurium is also used in solar cells, infrared detectors, and thermoelectric generators.

Tempera

== Description ==
A water thinned paint that dries to a water resistant film. Egg tempera is an aqueous emulsion paint with an egg yolk or whole egg binder that originated in medieval Europe. These paints dry to a semi-matte appearance by the evaporation of water and the coagulation of the egg protein. After about 1400 CE, variations of tempera were made with egg/oil, gum/oil, glue/oil and other emulsions as artists began to experiment with drying oils. As linseed oil paints became popular at the end of the 16th century, tempera died out. It enjoyed a revival near the end of the 19th century when Cennino's treatise was published. 
Some other water thinned paints that dry to form a water soluble film are sometimes incorrectly called tempera paints (e.g., distemper, gouache, poster paint and watercolors).

Temperature

== Description ==
A measurement of the hotness or coldness of an object or of the environment. The International Standard (SI) units for temperature are degrees Celsius. The Celsius scale is set as a linear function of the thermometric properties of pure water. The freezing point of water at 1 atm (sea level) is designated 0C while the boiling point of water is designated as 100 C. The one hundred degree differential gave the scale its first name of centigrade. The Celsius scale related to the archaic Fahrenheit scale by the equation: T (C) = 0.555 [T (F) -32 ] .

Tempered glass

== Description ==
A high strength plate glass that has been reheated and held above its annealing point (650C or 1200F), then flash cooled. Tempered glass was first used in 1942. The tempering process makes the glass 3-5 times stronger than ordinary plate glass of the same thickness (Konrad, 1995). However, it cannot be cut, shaped, drilled, or ground. On impact or damage, the entire piece of tempered glass will shatter into small, granular pieces with round-edges. Tempered glass is typically used for large doors and windows, display cases, tables, shelves, aquariums, refrigerator trays, cookware, and mobile screen protectors. Automobile windows are also made of tempered glass with the windshields having an additional laminated layer to provide containment of the particles when shattered.
== Synonyms and Related Terms ==
vidrio templado (Esp.); verre trempé (Fr.); gehard glas (Ned.); vidro recozido (Port.); vidro temperado (Port.); heat-strengthened glass; hardened glass; toughened glass; safety glass; Tuf-Flex [Libbey-Owens-Ford]; Herculite [PPG]
==Environmental Risks==
Tempered glass is not recyclable.
==Physical and Chemical Properties==
The glass has tensile stresses within the body that are balances by compressive stresses on the surface. When viewed through a polarizing filter, tempered glass shows variations in stress
==Working Properties== 
* Can not be cut or shaped. Must be made to size and shape prior to tempering.
* Smoothing edges and drilling holes must also be done prior to tempering.
* Tempered glass is most susceptible to failure due to damage at the edge.

In 1932, as solid moldable form was marketed for used in plastic parts, such as steering wheels, light switch plates, radio knobs, and poker chips. In 1938, Tenite II, a cellulose acetate butyrate compound was introduced. Tenite polyethylene and Tenite polyprolyene products were added in 1954 and 1962, respectively. By the end of the 20th century, the name Tenite was used only for celllulosic polymers composed of cellulose acetate, cellulose acetate butyrate, and cellulose acetate proprionate.

Tenorite

== Description ==
A dark gray to black copper oxide mineral with a metallic luster. Tenorite was named for G. Tenor, in Naples about 1860. While it can occur as an ore, tenorite has also been found as an alteration product of cuprite forming a thin dark layer over the red. The presence of tenorite as a patina may indicate the object was heated before or during burial (Scott 1997). In a basic environment of a burial site, tenorite has also been found as an alteration product of azurite (Gutscher et al 1989).

A soft, silvery gray metallic element. Terbium is a rare earth element was first identifies by C.G. Mosander in 1843. It has an abundance of 0.9 ppm in the earth's crust and occurs in apatite, monazite, cerite, gadolinite, and xenotime. Terbium is obtained as a byproduct in the processing of yttrium. It oxidizes readily in moist air and bust be handled and stored in an inert atmosphere. Metallic terbium is rarely used, but its salts have several applications . Terbium phosphate produce green phosphors for television tubes. Terbium oxide is used as a stain for ceramics. It also makes a colorless glass that has a strong blue-green fluorescence in ultraviolet light.
