Title: Method for forming an inorganic thermal radiation control

Abstract: A method is disclosed for forming a water-based inorganic coating capable of controlling thermal radiation which method comprises applying a layer of a semiconductor pigment upon a highly reflective substrate having a metallic layer and overcoating the pigment layer with a layer of an alkali metal silicate, and heat curing the silicate layer at above ambient temperature, where the two-layer laminate so obtained exhibits high absorbance of visible spectral radiation and low emissivity of thermal radiation.
