In the domestic glass segment the Quarzwerke Group supplies raw materials for a whole range of important products that are largely manufactured by mouth blowing processes, mechanical blowing or pressing. The products range from decorative glass products—i.e. drinking glasses, glass ashtrays and suchlike—to the porthole doors of washing machines. In this case, it is the scratch resistance of the glass in particular that is the important factor for its use in industrial production—no other material would ensure a clear view into the drum for the lifetime of a washing machine. The chemical insensitivity of the glass is also of immense importance for this special use, this feature being guaranteed by our high-grade raw materials. You can also benefit from this optimal raw material quality. Speak to us about it. We look forward to your phone call!
