Re: [ATM] Mirror stuck on pitch lap

[Guy Brandenburg <gfbrandenburg@yahoo.com>]

It might take overnight in the freezer. When you take them out, it will tend to come apart as they warm up as well. The pitch lap will probably be shot, unfortunately. You can get off the little bits of pitch that stick to the lap with turpentine. I would not go with the whacking, if I were you. Next time use a bit more polishing compound.
This sort of thing happens from time to time, but you will find a way out.
Good luck.

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?
