[i]Special bandsaws have been developed for doing this kind of work. To protect the rocks from contamination and reaction with air, the saws are enclosed in a nitrogen cabinet. The rock is clamped to a sliding table and advanced into a stainless steel blade which has diamonds in the cutting edge. Since the lubricants and cooling liquids normally used in sawing rocks would badly contaminate the lunar samples, the sawing is done dry and very slowly to prevent overheating.[/i]
[i]All sample processing is carefully documented in folders called data packs. Pieces which have been removed from the original sample are assigned new sample numbers, and the masses for all samples are accounted for to the nearest 10 milligrams.[/i]
