Customer Questions
I have used a casting mould for the first time and prepared using ZYP Boron nitride spray as per instructions. The cast glass has come out rough on where it has been In the mould. Am I doing something wrong? How can I remedy this problem do I need to polish fire pieces? Thank you

If the pieces are coming out rough this indicates that not quite enough boron nitride was used, you can clean the pieces off and firepolish them this will make them smooth.
