The technique of verre eglomisé, decorating glass with engraved gold and silver leaf on the reverse, was developed in antiquity. However, it was the French frame-maker Jean Baptiste Glomy (d.1786) who popularised the methods and after whom it was named. The fashion spread through Europe, notably Germany, Austria and of course Venice, but due to the delicate nature of the decoration relatively few examples survive in good condition. Count Lothar Franz von Schönborn established a mirror manufactory in Lohr, Bavaria, in 1698. For a similar Lohr mirror, see Heinrich Kreisel, Die Kunst der deutschen Möbels, Vol II., Munich, 1970, fig. 215.
