To cut it clamp between two pieces of wood faced with paper to support
it and make the cutting strokes slow and towards the silvered face. If
you work it hard the material will melt and clog the saw. It melts
very easily.

Thanks for that. Seems a good suggestion

Just realised the way I wrote that is ambiguous. You have to work so
that on the cut stroke you are pressing the mirror against the plastic
the other way around or an aggressive back stroke and the silver will be
rip off the surface around the edges. It is surprisingly easy to melt
the stuff and smell the monomer even with careful slow working.

If the swarf comes off in large melted together clumps you are too fast.
