Glass will not cast down to that thin a section. The physical
characteristics of glass will permit it to flow to a 6mm thickness and no
more. As an aside, casting a glass does not change the chemical properties
of the glass as the temperature for casting is below the vapor pressure of
the glass constituents. Annealing thin section of glass is not an issue
either as at 6mm the glass will be more or less self annealed. If you have
access to someone who is a glass blower you can blow glass to sections
thinner than a hair.

Perhaps a stupid sugestion , perhaps let it melt down to the right
thickness ??



Not a bad idea - but by melting it down and re-annealing you are more
than likely to be changing the physical and chemical properties of the
glass, which is no good for my application.
