- causing salt crystals to crystallize from the solution onto the glass fiber mat and thereby obtaining a glass fiber mat saturated with salt crystals;
- preparing a gypsum slurry;
- and
- forming a gypsum product by covering the gypsum slurry on at least one side with the glass fiber mat saturated with salt crystals.
