For many years we have been providing—with our low-iron sand—the basic material for glass production of the highest quality level for the sheet glass segment. The special quality of our high-grade silica sands, which are especially well suited for glass production, is the reason for this. This is due among other things to their particularly high proportion of SiO2 and the absence of any pigmenting accompanying minerals. Many manufacturers of high-grade glass products in the sheet glass segment are familiar with the special quality of our raw materials, which is why they opt for the Quarzwerke Group. We are delighted that we are able to make a valuable contribution with our premium silica sands to the making of equally first-class sheet glass products. You can also benefit from this!
