Abstract: It is difficult to recycle colored glass bottles except for transparent and brown colored to bottles. As an effective way of re-using glass bottles, the possibility of its addition to ceramic ware was evaluated through study of the vitrification behavior of ceramic bodies with recycled glass bottle as a flux source in the clay (40%) - flux (60%, feldspar-glass). with increase in the substitution ratio of feldspar by the recycled glass, the vitrification temperature of the body decreased and was lowered by more than 200? when the feldspar was fully substituted. The flexural strength of the fired bodies became higher with increasing firing temperature, reached a maximum and then decreased sharply. The maximum flexural strength attained was higher as the substitution ratio of feldspar by glass increased. In the glass-substituted bodies, anorthite and nepheline were formed on vitrification, indicating that the glass had reacted with the kaolinite in the clay. In addition, the amount of coarse quartz particles that are considered to be sources of rupture also decreased. This appears to be the reason for the higher flexural strengths reached by the glass-substituted bodies.
