teacher error

I am a middle school teacher and I started a glass fusing program at the school.  We have been successful until I tried a deep bowl mold. I followed the instructions and set the high temp to 1340 for a deep slump. The pieces over flowed and have become fused with the ceramic mold.  Is there any way to fx this? Any suggestions?  Thanks so much.

1340 F is to hot for most

1340 F is to hot for most slumping.

Did you kiln wash the mold?
