Mentors - I need help again.

My 8" mirror project has been dormant for more than two years.  My
tool (pitch lap) has been stored pitch up in a covered tray.  Today I set
myself to figuring after finally making sense out of Mr. Foucault.

I warmed the tool to about 80 degrees and pressed it with a mesh and cerium
oxide for about 1 hour with a 30 pound weight.

But even after so severe a pressing the mesh was not taken up in the pitch
and I fear the pitch is too hard to take the pressing.  What should I do?
More heat?  New pitch?
