Raw materials : weighing,
mixing and supplying
Furnace :heating rawu materials to > 1560°C
Refining oven : cooling liquid
glass down to 1100-1300°C +
removing light bubbles and impurities
Tin bath : glass mass onbath of liquid tin in correct
thicknessPerfect
planimetry.
Cooling :take away
tension and distortion +
slowly cooling down
to 600°Ctill ± 200°C
Cutting :cut cooled glass
to sizeProcessing : tempering,
bowing, sandblasting…
