Nice work John. It's been a long time since I've had the fun of machining a casting.
I assume by the blackening around the casting, that you use an oil tempered sand? Is it your own recipe or do you buy it already mulled. And what about flux? I know chlorine type degassers are used for aluminum, but do you also use some sort of flux for the bronze?
