I have a question for the list. How do refiners make your scrap
metal leftover from sprues and buttons, etc., into casting grain?
I normally reuse my sprues as 50% of the mix with new casting
grain for my casting in sterling and in gold. I’ve always heard
that you can’t use the old stuff 100% by itself. But, if I were
in a pinch, is there a relatively simple way to recycle the
leftovers myself? Often I will take the leftover buttons and
remelt them, and pour the melt into a bucket of cold water to
make it into smaller bits easier to melt for the next cast. Is
there something I could add to the metal when doing this to make
it “new”? This question comes up because I was weighing some
waxes last night, and realized I might be a bit short of casting
grain. Turns out I have enough for this go-round, but who knows
when an emergency may arise? Plan ahead is better, I know, but
we all know sometimes we just plain forget!
Thanks in advance. Leaving Thursday for ArtiGras in West Palm
Beach. Hoping for blue skies all around!
