Glass melting
At the start of 2013, a techno-
logically advanced glass melting
furnace was put into operation
- with increased capacity and sig-
nificantly enhanced energy effi-
ciency. The furnace is driven by
an advanced system for natural
gas combustion with pure oxygen
(Oxy-Fuel Technology), and is
a product of Steklarna Hrastnik
know-how and that of the sup-
plier - SORG. Using oxy-fuel
technology contributes to a better
quality of glass and, a the same
time, the significantly increased
energy efficiency of new furnace
has also contributed to a reduc-
tion in environmental impact.

Production processes - automation
Steklarna Hrastnik has a
number of production lines for
blow-blow, press, press-blow
and manual production, with the
manufacture of tableware and
packaging glass being automat-
ed. Steklarna Hrastnik is con-
tinuously working to achieve fur-
ther automation and an increased
optimization of production pro-
cesses, particularly in the field of
product quality control, following
its strategic goal of top quality
products.
Creating glass is a challenging
technological process carried out
with chemical and physical pro-
cedures. The two most important
factors are temperature and time.
Currently, Steklarna Hrastnik is
very advanced in:
- cooling of glassware and tools;
- flame polishing of glass prod-
