In this paper, the composition of lead glass was studied to lower the melting temperature. The composition of lead glass was silica, lead monoxide, sodium hydroxide, and other metal oxides which were blended in alkaline aqueous solution. The blend was dried and melted to produce transparent glass material. Using the composition suggested in this paper, it was possible to manufacture transparent lead glass easily at 700 ~ 900 ℃. And the dried blend material had very low softening temperature around 200 ℃ which can be applied in inorganic adhesives.
