I have a project for a pair of wedding bands in sterling silver and
18ct yellow gold (I know, I know but they wouldn’t have 18 white!).
Imagine 2 square interlocking strips that run parrallel for say
quarter inch then cross over and you get the basic idea. I can
fabricate one part and intend to cast the second, lost wax and
vacuum, onto the first component.
I assume I need to fabricate the 18 yellow and cast the silver but
am worried that I am still pouring silver in at or slightly above the
melt temp of the gold.
Will 18 hard solder stand up or do I need to cast the gold as well?
I am still happier fabricating than casting. Any pointers welcome.
