Dear all,

This time a question from me.
In literature a number of different glass types are reported. It concerns
some names probably originating from the former eastern European producers?
Names such as: Rasotherm, Uviol-glass, or Supremax (last one used by Fiedler
and Proksch, 1972) were used. Can anyone explain to me what types of glass
these are? Borosilicates, silicate glass, .... and what is a comparable
quality in common glass types.

I hope to get a fast answer - I will move soon from this address and I will
not be able to look into e-mail as regular as I am used to for the comming
month.

Best wishes,
Pier.
