The Adherence of Aluminium to Glass and its, Technical Applications

JSGT 1937 V21 T428-T435 

Under certain conditions glass surfaces are readily metallised by spraying with aluminium. The metal coating is tenaciously held by the glass. Preferably, glass to be metallised should be toughened to resist the chilling action of the blast from the spraying gun. The reflecting power of aluminium-coated glass enables mirrors to be utilised in adverse weathering conditions, for mirrors at cross roads, and pavement lights. Hollow glass bricks coated on the inside with aluminium greatly reduce the radiation losses obtained with the untreated bricks. Aluminium resistances on glass, in the form of strips sprayed in a zigzag manner make efficient glass radiators, whilst floor blocks, coated with aluminium and forming a continuous electrical connection enable heated floors to be used in offices and other rooms, the power expended being approximately 1200 watts per 8 square metres to maintain a floor temperature of 30°
