ABSTRACT:
A decorative mirror having a reflective silver layer deposited on a transparent sheet. A substance which reacts with silver is applied to the silver layer to create randomly distributed areas containing reaction products including non-metallic silver where the visible light reflectance of the mirror is modified or interrupted. In order to manufacture the mirror, a transparent sheet is wetted with a silvering solution to form a reflective silver layer, and while the sheet is still wet with the silvering solution the sheet is contacted with randomly distributed droplets of a solution of a substance which reacts with silver, the two solutions being made up using different solvents. The substance which reacts with silver may be a tin compound in an alcoholic solution, the silvering being effected with an aqueous solution. The silver layer whose reflective properties have been modified may be overcoated with a second silver layer, and the whole protected with further layers, for example of copper and paint.
