was added to the glass powder as described below and a 1 25 inch square shaped sample was pressed the polyvinyl alcohol binder was first dissolved in water and then mixed with the glass powder the glass binder mixture was dried in an oven at about 90 u00b0 c to remove the water the dried mixture was ground with a mortar and pestle and sieved through 30 mesh after the pressing and firing steps a high quality ceramic product resulted similar to example 1 with a density of 2 60 g cc and smooth glaze like surfaces the same procedure described above for example 1 was also used for this example except that the fiber glass waste used in example 1 was replaced by a third e glass continuous fiber glass waste and the glass was heated to 800 u00b0 c before grinding in the mortar and pestle this waste was obtained from a fiber glass manufacturer and had a larger amount of organic size applied compared to the fiber glass waste used in example 1 the fibers were about 12 inches in length which was much larger than the fiber lengths of the fiber glass waste used in example 1 a high quality ceramic product resulted similar to example 1 with a density of 2 60 g cc and smooth glaze like surfaces the same procedure described above for example 7 was also used for this example except that six weight percent polyvinyl alcohol binder was added to the glass powder as described below and a 1 25 inch square shaped sample was pressed the polyvinyl alcohol binder.
