Lou, when the crushed glass breaks down does it just disappear as dust or 
does it just quit cutting good?  The reports I read were evaluating crushed 
glass for outside blasting with air or water so only for single use, but 
the crushed glass is not much more expensive than silica sand in my 
neighborhood.  But, glass beads are almost ten times as costly as crushed 
glass.   I guess the important issue to me would be if the fine crushed 
glass would be too aggressive in a blast cabinet.   Guess I'll find out 
later.      John W.
