Potassium silicate is a water-soluble and glass-forming silicate salt of general formula K2SiO3 with many common uses for at least a century.
Impregnation of wood with a potassium silicate solution is an easy and low cost way for rendering the woodwork of houses secure against catching fire. The woodwork is first saturated with a diluted and nearly neutral solution of potash silicate. After drying, one or two coats of a more concentrated solution are usually applied.[1]
Inhorticulture, potassium silicate is used as a soluble source of potassium and makes also the growing medium more alkaline.
Some metal cleaning formulations use potassium silicate, which also serves as a corrosion inhibitor.[2] It also finds various uses in the fabrication of welding rods or even of cosmetics.
