Abstract

The reuse of the glass from cathode-ray tubes in the glass industry requires that this glass have a high level of purity. The cathode-ray tube screens, which are coated with different metals, cannot be reused unless this coating is removed. By cleaning the coated glass in an ultrasound bath, this coating can be removed to the extent that the glass obtained from the previously described method can be used as a secondary raw material in the glass industry.
