Hi, This is Tom Phillips, the microscope guy, which really means the
polishing guy. I have to agree, Ghubara is both tough to polish with out scratches
and when I revisited some polished slices I had made a year ago, all were
good except the Ghubara. It had to be repolished before any scope time.

Perhaps some one can suggest a sealing method that would work for your
sphere?

Be carefull, becouse
primo, ghubara is hard and every scratch from grinding will be visible on
polished slice.
secundo, Ghubara is one of the best ruster I have seen in chondrites.
