Sounds reasonable and yet I will expect that if hot pressed mirror-tool assembly
is left to cool down, pitch will "follow" the glass contracting curve.

If purpose of hot pressing is to speed up pitch reshaping than this advantage
may be lost or diminished by waiting for assembly to cool down. It seems
that Michael advice for cold pressing is sure bet in any case.
