Pair Of Blue Opaline Bottles, Restoration Period.

Pair of blue opaline perfume bottles. Each bottle has a decoration on the belly framed by two gold threads. The decoration consists of a floral frieze characteristic of the decoration of Desvignes' workshop. Indeed, silver forget-me-nots with blue hearts, roses and gold foliage are found in many of Desvignes' compositions. The independent stoppers are decorated with motifs of silver roses and gold leaves. The main components of the opacification of crystal at this time were bone ash, tin or arsenic. The "opal colors" are obtained by adding salts or metal oxides. Jean-Baptiste Desvignes was a decorator active in Paris from 1817 to 1826. He was a painter, gilder on porcelain and crystals. In 1817, he filed a patent for a process of gilding and painting crystal without firing or incrustation in the crystal.
Restoration period. Circa 1820-1830
