Glass glue is a family commonly used adhesive, the main ingredient is sodium silicate (Na2O·mSiO2), soluble in water, viscous, also known as sodium silicate in the south, also known as paolin in the north. Sodium silicate is a colorless, slightly colored transparent or translucent viscous liquid in the system with water as dispersant. Solid sodium silicate for colorless, slightly colored transparent or translucent glass block. Form is divided into liquid, solid, water quenched three. In theory, such substances are called colloids.
Common sodium silicate is slightly light blue block or granular solid, after high temperature and high pressure dissolves, it is to take color slightly transparent or translucent viscous liquid.
