[ATM] Mirror stuck on pitch lap

[Francis J. O'Reilly]

Guys and ladies,

I poured a pitch lap today (Gugolz 64) and while hot pressing with cerium
on the mirror, it became stuck to the pitch lap. I have tried putting the
entire project in the freezer for a couple of hours to unstick them, to no
avail. I tried the bigger hammer method by knocking on the dental stone
tool with a hammer shielded by a piece of wood, no luck.

Any suggestions?
