I was visiting with Val Carver at Minnesota Lapidary Supply-he is a fount of great lapidary information.This time he showed me a dozen small cabs of the same shape and size that an old time cabber had polished as examples of his work.I had to agree with Val that these were as good as it gets.They were all of different material and ranged in hardness from about 5 to seven-and -a-half,all done together.He uses a Gy-Roc 10#. He uses 800A.O. as a pre-polish,one Tablespoon per 10# of load.Then Rapid Polish#61 about one teaspoon per 10#--no more!Two day runs should do it.He also adds about the same amount of cheap hair-gel --this probably starts he slurry faster and acts a a surfactant.
Also important,he uses about 80% small size plain[uncharged] ceramic cylinders-this really works the load.
Val tells me that the only thing he has found that R.P.#61 won't polish well is feldspar.Try it I think youl'll like it.Mike.
