Perlite is not a trade name but a generic term for naturally occurring siliceous rock. The distinguishing feature which sets perlite apart from other volcanic glasses is that when heated to a suitable point in its softening range, it expands from (4 : 20) times its original volume. This expansion is due to the presence of (2 – 6 )% combined water in the crude perlite rock.
The expanded perlite is then moved away from the burner and allowed to cool. Another embodiment of this invention is directed to a method of making a gypsum product. The method includes annealing perlite by the method described above, then preparing a slurry of calcium sulfate hemihydrate, additives, water and the annealed perlite.
