I am casting small (up to 10") sculptures using a 50-50 casting plaster & silica mix and clear bullseye cullet. I have experimented with various schedules but it seems no matter what I do, the surface of my pieces come out murkey and rough. Short of polishing, what can I do to get a smoother finish? Would switching to a different kind of investment improve my chances? Any suggestions would be gratefully appreciated. Thanks, Lisanne
