| [381] A peek into the X Files on new Platinum Sterling |
It took about two months of experimentation to get the formulas for Platinum Sterling Silver just right - Robinson created alloys containing 5 percent, 3.5 percent, and 1 percent platinum. But he's the first to admit that combining silver and platinum isn't a novel concept..... (2004)

| [299] Alloys - Look on the White Side |
In the jewelry industry, it's rare to have an alloy without drawbacks, particularly when the alloy is not yellow. When designing alloys, there are a number of hurdles to jump. First, color is absolutely critical. Unfortunately, we alloy designers have a relatively limited palette to work with. Gold and copper are the only two metals that are truly "colored;" all others are varying shades of gray. So when we design a white alloy, we don’t make it "whiter," we make it "less yellow." ....

| [354] Brepohl on White Metals and Alloys |
In practice an experienced eye will usually be able to determine by color and luster whether a piece is made of silver, a base white metal such as nickel silver, or a precious white alloy such as white gold or platinum. If this can be determined by eye, it's usual to proceed directly to the qualitative test.... (2001)

| [216] Carat Gold Solders |
In many countries, regulations govern the caratage of gold solders used to make jewellery and, with few exceptions, gold solder alloys should be of the same caratage as the jewellery. One problem with the production of solders is to ensure a good colour match with the jewellery being assembled.... (2003)

| [961] Causes and Prevention of Defects in Wrought Alloys |
Much of the recent literature on defects that occur in jewellery manufacture is focused on those occurring in lost wax investment casting. However, defects can also occur during casting of ingot and its fabrication into sheet, tube, wire and rod as well as their onward fabrication into jewellery components by processes such as stamping and forging. These defects, along with their causes and prevention, are briefly reviewed in this article, although those defects occurring in the die-striking of findings are described elsewhere in this issue....
