Hi Karen,

Tried your method to make glass knives but did not have much success.
If you have any references I would appreciate having them. I actually 
have a glass knife making machine for Ralph Knives which I gave up on 
ages ago.  I would like to give it another bash as I have the holder 
for Ralph knives for the micrtome in my lab. 
I know they are pretty tricky to make.  I have never been sure as to 
the thickness of the glass one should use. 
  
Many Thanks,
Sharon Marshall
