White gold is an alloy of gold decolorized by the addition of palladium. Like gold, palladium can be beaten into leaf as thin as 1 /250,000 in. The metal is used in dentistry, watchmaking, and...

Ozone and sulfur dioxide mixtures are of special interest, because of their widespread occurrence and the greater than additive effect on Bel W, tobacco. Concentrations of either or both that may cause foliar injury are found around major metropolitan areas throughout the world and are widespread throughout rural eastern United States. Macdowall and Cole reported that the two-gas combination lowered the threshold for injury of tobacco (cultivar White Gold) by sulfur dioxide, but not the threshold for ozone injury. Macdowall et defined the threshold in terms of dose when th reported the threshold at 20 pphm-h (0.20 ppm-h). This has not appeared true in several other reports, nor within the results reported by Macdowall and Cole. Symptoms reported, when sulfur dioxide was below the threshold for the specific plant, were similar to those reported for ozone.

It was originally found in gold ores from Brazil, where the miners thought the gold was contaminated by what they referred to as white gold. Later, it was considered an alloy combination of palladium and gold. 

Palladium is used in the manufacture of surgical instruments, electrical contacts, springs for watches and clocks, high-quality spark plugs, and special wires and as white gold in jewelry. Because it is noncorrosive, it is used as a coating for other metals and to make dental fillings and crowns. 

The Joy of the Philosophers occurs when the Stone, or Matter of the Philosophers, has arrived at the perfect White Stage, which is called either the Philosophical White Gold, or White Sulphur, or Endica of Morien, or the Swan. Then all the Philosophers say that this is the time of joy, because they behold the unveiling of Diana, and they have avoided all the rocks and dangers of the sea. The Code of Truth remarks Whiten the Eaton, and then destroy your books, for then have they become useless unto you, and will serve only as an encumbrance, a source of doubt and disquietude, when you should experience nothing but joy. 

In 1752 H. T. Scheffer published a detailed scientific description of platinum, or white gold, as he called it, and, with the aid of arsenic, succeeded in fusing it (42). Henric Theophil Scheffer was bom in Stockholm on December 28, 1710, where his father was secretary to the Royal Board of Mines. After serving an apprenticeship under Georg Brandt, he established his own laboratory and made trips to the mines to learn firsthand the close connection between smelting and assaying.

How can an expensive white-gold ring contain the same amount of gold as a cheaper white-gold ring and yet be more dense ... 

Two or more metals can be bonded to each other by metallic bonds. This occurs, for example, when molten gold and molten palladium are blended to form the homogeneous solution known as white gold. The quality of the white gold can be modified simply by changing the proportions of gold and palladium. White gold is an example of an alloy, which is any mixture composed of two or more metallic elements.
