FAQ's


What is the temperature of the annealing ovens?


At the start of the process, "annealing ovens" have a temperature level corresponding to the production temperature/forming temperature, and at the end of the process, that of the ambient temperature. This is an individual temperature/time profile dependent on the product/type of glass.


At what temperature does glass begin to melt?


Depending on the type of glass and on the glass batch composition, the melting temperature is between approximately 1000 °C and 1600 °C (1832 °F and 2912 °F).


How is colored glass made?


Glass that is colored throughout can be produced by adding coloring materials, subsequent colored coating or transparent imprinting is also possible


How is opal glass made?


Opal glass is made by frosting clear glass, or made as frosted translucent glass or as clear glass with white screen printing.


How is glass produced?


Glass is melted in vats with fireproof cladding, which nowadays are heated by oil, gas or electricity, and is then
a) drawned, rolled (flat glass) b) pressed, blown (hollow glass)

and, if necessary, subjected to further processing:

a) coated
b) imprinted
c) polished
d) drilled
e) faceted
f) frosted
g) tempered/pre-stressed
