Oxides that are harder to remove, such as those generated with nickel white gold alloys, can be removed by using 5% nitric acid. Fire scale is best removed form silver alloys by using a 10% sulfuric acid. If you do not have 10% sulfuric acid, but a higher strength, always add the acid to a larger volume of water when diluting.
Red golds are popular now and obtaining a red easy solder is a common problem. It is just not possible to formulate. Solders are formulated to melt before the gold that you are soldering. Typical metals used to lower temperature are zinc or cadmium. The high copper content and the high melt temperature for both gold (1945°) and copper (1981°) prevents the result of a lower melt temp solder. If the appropriate amount of zinc and/or cadmium is added, the resulting solder turns yellow, not red. Our recommendation for a lower melt temp solder is to use 14KY Medium.
