Cuttlefish cast brass

Hi, neighbors,

I have a student who wants to cuttlefish-cast using brass. I’ve done
this before without a problem, using brass casting grain. I don’t
currently have any of that, so I’m hoping someone more experienced
with casting (I am competent but not expert) will tell me whether it
will work as well with cut-up nugold sheet? Is there a difference
between sheet brass and grain? If casting needs more zinc, I suppose
I could use pennies…?

Thanks for any help and guidance!

I don’t know about ‘nugold’ but …

Brass sheet is usually plain old 70/30 Cu/zinc. Cut into small even
pieces.

Brass screws, however, may have a little lead in the mix, so
probably best to avoid melting that at home.
