PROBLEM TO BE SOLVED: To provide a glass commodity with increased added-value as a member for improving environment by recycling a large amount of recovered glass bottles as a nonindustraial waste, particularly colored bottles that are said to be difficult to recycl as bottles by allowing a power of an inorganic material to adhere thereto. SOLUTION: Crushed particles 1 of recovered glass bottles, particularly colored bottles, are coated with an inorganic binding material 2 and an inorganic material 3 is adhered onto the inorganic binder layer 2 by sintering to produce continuously porous glass-sintered product 4. In a preferred embodiment, the inorganic binder 2 is admixed to the glass particles in an amount of 10-20 wt.% based on 100 wt.% of the glass particles, in addition an inorganic material powder is added thereto in an amount of 1-10 wt.% and the resultant mixture is sintered.
