Water glass is the common name for an aqueous solution of either sodium silicate or potassium silicate. It's also called "liquid glass". It gets its name because it's essentially glass (silicon dioxide) in water. As the water evaporates, the solution solidifies into a glassy solid. Chemical Formula of Water Glass
Knowledge of sodium silicate solution, also known as waterglass, dates back to at least the period of the early Roman Empire.
