Colorless or yellowish translucent to transparent glass. hygroscopic. Strong alkaline reaction. decomposes in acid to precipitate silicon dioxide. Slowly soluble in cold water or almost insoluble in water (depending on its composition), insoluble in ethanol. Potassium silicate is commonly used in the manufacture of welding electrodes, welding electrodes, vat dyes, fire retardants. It is also used as a screen coating and soap filler.
