Re: IONS

The difference between "glass" and "quartz" is a matter of crystal structure
not purity or chemical composition. Having a crystal does not ensure purity.

remember that 'glass' is seldom pure SiO2. It is called quartz when it IS pure.
Glass(es) include various 'fluxes' that help them melt at a lower
temerature than quartz does. Flux, such as NaBO4, could certainly
contribute to conduction.


Remember also that a temperature of 500 C leads to the Maxwell-Boltzmann
distribution of kinetic energies rather than one SINGLE energy value.
