The claimed method is characterized by mixing a crystallization glass powder and one ceramic powder selected among beta-spodium, alumina titanate and codierite. Pref. beta-spodium is produced by adding a basic composition of Li2O Al2O34SiO2 to transition metal oxide selected from the group of MnO, NiO, MgO, ZrO2, CoO, and Fe2O, and Al2O3 system forsterite is composed of 60 wt.% ZnO, 25 wt.% B2O3, 10 wt.% SiO2 and 5 wt.% MgO. Pref. alumina titanate is produced by adding a basic composition of Al2O3TiO2 to a transition metal oxide selected from the group of SiO2, Fe2O3, Clay, Talc, NiO and CoO, and codierite is produced by adding a basic composition of 2MgO2Al2O35SiO2 to a metal oxide.
