Prodn. of high strength, natural stone-like, construction and decoration slabs, involves forming a flat uniformly thick layer of a mixt. of broken glass, mineral components and finely divided additives in a temp. resistant mould, drying at 60-110 degrees C in the mould, heating the layer at 0.5-3.0 K/min. to 720-1100 degrees C, holding at temp. for 20-120 mins. and cooling at 0.5-3.0 K/min. to room temp. The novelty is that the mixt. is produced from (by wt.) 85-98% broken glass, 0-14.7% mineral component and 0.3-5% total finely divided additives. Also claimed are construction and decorative materials, of bending strength at least 14 MPa, produced by the above process.
