Cool the coverslip on the opposite side of the crystal with a chip of dry
ice. Do not freeze the drop. I learned this from Gary Gilliland. Also I
wonder if you can simply move the whole tray into a cooler temperature?
You can imagine that the thermal expansion coefficient of the glass
coverslip and the crystal are different. I have not tried heating, but
maybe that works, too?
Or bend the coverslip without breaking is by applying pressure from the
opposite side.

Any suggestions for detaching crystals from cover slides will be
greatly
appreciated.
