Description: Sodium Silicate, also known as water glass, it has two forms: liquid and solid.
The liquid is common, colorless clear or light gray deup. The solid is light blue or light green crystals, transparent or semi-transparent .
Sodium Silicate is made from sodium oxide and silicon dioxide, the molar ratio between them called modulus, the physical property and usage would be different if the modulus changes.
