<p>A process of making a blistered, crystallizable glass material, whereby calcareous and siliceous raw materials are introduced into a rotary kiln, melted and then discharged, cooled and possibly crystallized, characterized by introducing as raw materials a mixture of materials originating from domestic or industrial waste products, waste from purification of wastewater or any type of ashes from combustion kilns, with calcareous materials and optionally other glass-forming minerals. This process advantageously makes possible the industrial utilization of fly ash and slag from power works and refuse disposed plants which has formerly presented serious pollution problems.</p> |
