As far as borax is concerned, the best borax to use is anhydrous borax but don't expect it to help purify your melt, it will not. It will allow the molten metal to flow easily out of the crucible, but by itself, without help of other flux components or lead to perform the oxidizing of the impurities, it will do little to purify the melt.

The most known gold alloysare made with silver. The proportion between gold and silver changes the alloy color. In this way, there are yellow and white alloys and the last ones present different metallurgical properties. Alloys are influenced by the presence of other minerals or metals. The next table shows the melting point …
