I don't think I could use opaque plates - I get a lot of info and 
detail from transfused light, not to mention evidence of hemolysis of 
blood.

Of course no one can now go back to the old Pyrex glass petri dishes 
that require sterilization and washing, etc. Some times I don't miss 
the "old days"!
