Modern mirrors were made by the method invented by the German chemist Libig in 1835. The silver nitrate and the reducing agent were mixed to precipitate silver nitrate and attached to the glass. The reducing agent generally used is sugar or sodium potassium tartrate tetrahydrate. In 1929, the British Pilton Brothers improved this method by continuous silver plating, copper plating, painting, drying and other processes.
With the advancement of technology, the cost of mirrors has been reduced, and the emergence of a variety of curved mirrors has made the use of mirrors more and more widely, and has more uses than the mirroring. For example, a spherical rear-view parabolic mirror for use in automobiles, a parabolic mirror for collecting and reflecting parallel light in a searchlight in a telescope.
