Re[2]: THE BATTLE FOR MONAHANS - may be lost to water.


     Polling the List for non-aqueous rock cutting methods....
     
     I was refraining from asking this question - thought it might be 
     considered a "newbie" question - but after reading posts about hammers and 
     thinking out loud comments like, "Oh yeah! Water and salt, good point!", 
     I'm getting a little nervous.
     
     Question - how do rare, one-of-a-kind stonies get cut?
     
     Let's continue this discussion about waterless rock cutting - 
     Anybody out there have any suggestions?
     How did NASA/JSC Houston cut/make their tests?
     
     Water, OUT - hammer, OUT - rock trimmer?
     My experience with rock trimmers is that, how a rock breaks, is 
     dependent upon the matrix.  Makes a difference whether the break goes 
     through or around chondrules and crystals.
     
     My turn to think out loud - 
     Since cutting fluids are used to primarily cool the blade, the problem 
     is to find an appropriate replacement fluid.  If an air tight 
     enclosure could be placed around the saw/blade, and the oxygen was 
     replaced by another inert gas, would it be safe enough to use alcohol 
     as a coolant?
     
     Educate me,
     Bob V.

A hammer probably would not be a good solution either if I think of all 
those quartz and amethyst crystals I destroyed while trying to remove as 
much of the surrounding rock as possible when finding a druse in a 
quarry.
