Oil bonded sand is hard to work with when its cold so the first one that I poured was a little rough around the edges, the second was a lot better pour but I lost the bearing in the back of the vac motor I use for a burner blower so melt was really fun with a half a crucible full of half melted aluminum when the blower gave up the blue smoke.
Is it your own recipe and can you share it ?
