What's it being used for?   Are you going to be drilling any holes in 
it?  Could it be glass?

If a *near perfect* optical surface isn't your goal, then it might be 
cheaper to cast it from
bar-top epoxy, or even the polyester used for paperweights.

Or if all you really need is an electrical insulating material, then you 
could be using glass
cloth and resin, and winding an (non-transparent) laminated ring on some 
sort of crude
tuntable.
