Micro-mosaic decoration, which evoked the lavish decorations of antiquity, became enormously popular during the 18th century. At the end of the century, the technique of making micro-mosaics was refined and perfected in the Vatican Mosaic Workshop. The minute segments, or tesserae, were made from a type of opaque enamel called smalti. This material was heated and drawn into long thin sticks, or filati, and small sections were subsequently broken off to form the tesserae. These were attached to a support with a slow-drying glue, and once completed, only the cross-section of each filati was visible.
Some of the badly paid workers began to take commissions, and this was further stimulated by the Napoleonic occupation which boosted the secular art trade. Napoleon re-named the Vatican workshops the Studio Imperiale del Mosaico and ordered the 'Shield of Achilles' table, now at Versailles. By 1810 there were twenty small independent workshops in the area around the Spanish Steps, all of which were producing small souvenirs with micro-mosaic decoration. As these objects were so easily carried, the fashion for them began to spread rapidly, and a few years later this trade boomed even further with the greater prosperity brought about by the end of the Napoleonic wars. A wide variety of objects, including table-tops, snuff-boxes, plaques and jewellery were decorated with a wide variety of subject matter including topographical views, portraits, ornithological subjects, reproductions of antique sculptures or works by Renaissance masters. For a full discussion of this technique and its history, see Jeanette Hanisee Gabriel et. al, 'The Gilbert Collection, Micromosaics' Catalogue (London 2000).
