Dorfner melting sand for glass delivers a purity which is at the limits of what can be measured

Exploiting the full potential of glass

Dorfner melting sand for glass is the product of choice whenever architecture, aesthetic appeal or physical functions place special demands on an application and demand high chemical purity - whether for solar panels, TFT displays or top-quality glasses for drinking. There is one very special place in which glass symbolizes the importance of total transparency in Germany's political system – in the commanding Glass dome of the German Reichstag in Berlin.

Quality, efficiency and versatility

In its different available forms, GEBAFLOT® melting sand for glass from Dorfner has established itself as a universal product for the glass industry for the production of anything from flat glass to crystal glass and borosilicate glass. This range of products stands out with extremely low levels of impurities, particularly Fe₂O₃, TiO₂ or Cr₂O₃. The tightly restricted grain size range allows these products to be used in virtually all standard melting units - and this with minimized energy demands. Our top-of-the-range product, the High Purity Quartz Sand HiPu®, is widely regarded as a safe bet for demanding, technical glass. Our extremely low-iron, high-end melting sand for glass delivers highly light-transmissive special-purpose glass and crystal glass with precisely defined technical properties, and it also meets the toughest demands in terms of color and aesthetic appeal. If instead you need high-quality lead crystal or crystal glasses, then our kiln-dried DORSILIT® 010 melting sands for glass are the perfect solution.
