iPotassium silicate glass is a colourless super-cooled melt of potassium carbonate and pure silica sand.  Potassium silicate solution is prepared by dissolving potassium silicate glass in hot water.  By varying the silica to potassium oxide ratio, products of definite but widely different properties are produced.
