On account of the high quality and for the protection of the consumer, crystal glass is subject in Germany to the 'law on the marking of lead crystal and crystal glass', which, among other things, also clearly defines the various quality levels and the content materials. It is therefore understandable that only first-class and absolutely high-grade silica sands and feldspars are used for this product—a clear case for the Quarzwerke Group.
