| [664] Understanding White Gold |
White gold jewelry is a hot fashion trend that does not show signs of cooling off any time soon. Manufacturers are producing it, retailers are buying it, and consumers are demanding it, but none have a clear definition of what alloys can truly be called "white" -- until now. A White Gold Task Force led by MJSA and the World Gold Council, comprising members of the supply, manufacturing, and retail components of the jewelry industry, has established a definition of white gold.

Both methods require costly equipment, special procedures and a well-lit and ventilated area. A simpler method for determining gold purity in jewelry is the touchstone testing process, an age-old technique that is relatively nondestructive to jewelry and offers quick results.... (2011)

| [311] Working Titanium |
Because titanium behaves somewhat differently than the standard metals in the goldsmith's workshop some special attention to its working is in order here. When sawing, begin the cut with a very light stroke, and increase the pressure only when the blade has securely caught. The sawblade can be protected with a lubricating grease, but even with this precaution it will dull quickly. Titanium can be worked with standard files, but.... (2001)
