Re: [ATM] Fused Quartz Blank

That's the quartz inversion point, the crystal structure changes at that
point and the result (at least as I understand it from dealing with silica
flour) is crystabolite.

Mark:
      That's a very interesting chart on the GE website.  What is the  
reason the hardness for both Quartz and Silica increases around 600 C  
before dropping rapidly?  Thanks.
