With 35 years of experience casting I have learned that it is a very
forgiving process. Have you done any casting in the past? If so what
experiences have you had with the methods you have used? If you have
had good results casting other precious metals such as sterling or
other colors of karat gold than doing white gold will be no
For me I use an oxy/propane torch for casting and it works well for
me. The crucible to use for white gold is no different than the ones
used for sterling silver or other colors of gold. It is a standard
clay/silica casting crucible. As for melting the metal I like to use
neutral or slightly hotter flame depending on the amount of metal
Quenching should take place after the button is no longer red (
generally about 10 minutes after casting ).
Stuller settings has a white gold that they call X1 which gives a
fairly good white color but does have a fair amount of Nickel alloy
in it. Another choice would be an alloy with Palladium.
The keys to getting a good casting is based on some simple processes.
Make sure you have sprued the piece properly, A proper burnout cycle,
don’t overheat the metal and the one thing that has worked best for
me even casting metal that has been melted multiple times without
fresh metal being added is to use at least 50% more metal than the
piece with sprues require. I like to use the rubber bases that create
a large reservoir ( Rio calls them a donut design ) which allows for
a large button for the casting to feed off of. I use Satin Cast 20
investment for all of my casting.
Hope that helps.
