Hi Phil,

         You should not only ask with what stuff you should polish but also
what are you
polishing I mean that (in my opinian) Ce is best used for the harder
materials such as
Pyrex or Schott's Duran 50.However I like rouge and zirconium oxyde for
optical glasses as BK7 and certainly F2 or equivalent glasses.Also pressure
and speed are important1
