The production of glass is an energy intensive process. Due to the political pressure and climate change problems it is necessary to lower the energy consumption for glass production. A new way is the refinement technology of TU Bergakademie Freiberg, which minimise the interaction of refractory and glass melt and generates a saving potential of around 500,000 Euros. The refinement technology is a surface refinement of porous refractory bricks which lowers on the one hand the corrosion of the brick, and on the other the blistering and crystallisation behaviour in the interface glass melt and refractory. This is important for often changed components, such as orifice ring, plunger and tube. Tests in laboratory shows a decrease of the corrosion in static finger test about 80%. Also 80% less blistering and a minimisation of the crystallisation behaviour were measured. This fact creates the potential for a batch adjustment, which is attended by a lower ing of the fining temperature around 20K. Tests in industrial scale approve this tendency and the effect of the technology.
