Laboratory trials have been carried out to assess the possibility of replacing calcium carbonate in high-lime soda-lime-silica glasses with phosphogypsum, calcium sulphate dehydrate containing various impurities, including phosphates, fluorides and rare-earth elements. It was shown that opaque glasses of different colours, suitable for use as facing materials, can be made in this way.
