Tartaric acid

== Description ==
Colorless, transparent crystals that occur naturally in wine lees. Tartaric acid is used in baking powders (potassium hydrogen tartrate), leather tanning and effervescent beverages. Tartaric acid acts as a buffering agent and sequestrant. It is used by dyers to print a blue ferric tartrate color and to remove some mordants from solution. Tartaric acid (and tartrates) reacts with ammonio-silver nitrate to produce metallic silver; this reaction is used in photographic developing solutions and for silvering mirrors.

Tartrazine

== Description ==
A yellow monoazo dye discovered in 1884 by H. Ziegler. Tartrazine is used to color food, drugs, cosmetics, wool, nylon, jute, leather, silk, paper, and acid dyeable acrylic fibers. Because many people experience allergic reactions, the use of tartrazine as a food colorant is banned in Norway and Austria. It is still used in many other countries, including the U.S., in colas, candies, soups, jelly, and many other food products.

Teak

== Description ==
A dense tropical hardwood obtained from the Tectona grandis tree native to the southeast Asia has structural properties better than oak. Teak is a tall (up to 40 m) deciduous trees with diaeters up to 3m that have small fragrant, white flowers. Of distinction, are the huge papery leaves of the teak trees (up to 45 x 23 cm) with a hairy lower surface. Teak wood has a straight grain and coarse texture that is very resistant to insects and decay. It is used for high quality furniture, veneer, boxes, chests, doors, and shipbuilding. Teak wood also has an aromatic smell when cut that it can retain for over a hundred years. With age, the yellosish heartwood darkens with age.
== Synonyms and Related Terms ==
common teak (Tectona grandis); Dahat teak (Tectona hamiltoniana); Philippine Teak (Tectona philippinensis); Burmese teak; Nagpur teak; tekka; teck (Fr., It.); Tiekholz (Deut;); teakboom (Ned.); teca (Esp., Port.); teak(Sven.); jati
== Personal Risks ==
Skin contact, especially with sap, may cause irritation. Sanding dust may also cause an allergic reaction.
== Physical and Chemical Properties ==
Teak has a high oil content that is extremely resistant to decay. Density = 35-55 ppcf
== Working Properties ==
Teak is weather-resistant. High levels of silica in the wood facilitate planing and jointing, but may dull blades and cause irregularities in finishing. Carbide blades are recommended. Epoxy and resorcinol adhesives work best when joining teak. The wood does not stain well and will not accept emulsion based sealants, such as polyurethane. Without a finish, outdoor wood will weather to a gray color.

Technetium

== Description ==
An unstable radioactive element of the magnesium family. Technetium was the first artificially produced element in 1927. Carlo Perrier and Emilio Segre made technetium by the deuteron bombardment of molybdenum.

It is used to increase corrosion resistance of steel and, in medicine, as a radioactive imaging agent for the liver.
