Missing stress quartz calibration standards

Dear labmembers --

Two 4" thick quartz rounds which are used as calibration standards for 
film stress measurements have been missing for several weeks.  They were 
last seen next to the FSM stress test system across from Metalica.  They 
are about one centimeter thick and were kept wrapped in cleanroom 
wipes.  If you happen to see these in the lab, please let a staff member 

By the way, the new Flexus 2320 stress measurement tool is here and is 
functional (as far as we can tell, without the reference standards.)  
There are no operating procedures as yet and a couple more accessories 
need to be ordered, but it is usable.  If you'd like to use it, contact me.
