Adding 7.5% copper to molten silver does not sound like much of a challenge
either.

Rather than melting the silver and adding solid copper to it, just put both
together, cold in the crucible, with the copper on the bottom (to limit
oxidation), and melt both at the same time. You won't then need it to get
quite as hot, as sterling melts at a lower temp than either fine silver or
copper.
