Paul and I have several large pieces of Muong Nong that we have been cut and polished to near optical flatness. It is a long and difficult process taking about 60 hours. First grinding on a vibrating lap and then polishing on a wet lap charged with cerium oxide. Polishing is about 40 hours of the 60. But the lap s can handle several pieces at the same time. The results are fabulous. I don't know if the specimens are currently in our catalog at meteorite.com but maybe we can feature them as the Tektite of the Month in the next Meteorite Times.
The polished surface is so flat that the microscopic differences in strain on the glass that are relieved at the edges can be seen in the surface. They have been at our tektite parties maybe some of the attendees can comment further. It has been one of the most challenging and rewarding things Paul and I have done with the vast amount of Muong Nong we have. Wish we had time to keep the lap running more.
Looking forward to seeing many of you at Tucson. Cheers, Jim

Subject: [meteorite-list] Tektit "Muong Nong" and cutting
Hello
Anyone try cut Muong Nong tektites ?
I know, this is maybe destroying specimen, but from the other side this can
show interesting structure inside. Anyone ever see something like this ?????
Any opinion ?
