Sas I'm no expert at doing this, but have been messing with it for three or four years now and learn something just about everytime I make a pour. From what I have seen John aka Doubleboost is the goto guy for Brass and Bronze info, enough of that.
The mold that I posted the photo of Monday night didn't do so good, I messed around with the mold and as can be seen from the photo I removed the parts that were being used as the pattern and I guess it chipped loose the edge of the mold. Anyway when I did the top half and pulled them apart to remove the pattern there was a long strip down one edge that had chipped loose. Nothing that can't be fixed with a little filing but something that shouldn't have to be done. So for this particular part I think I will go back to the regular sand for molding them in, I have that process down pretty good where I only have a minimal amount of cleanup to do on them.
will post a photo later of the parts poured in the Sodium Silicate sand mold.
