Purpurine, a vivid opaque matte red glass, has long been among the most desirable of materials; the intense color often leads viewers to believe that it is a hardstone rather than glass. In Russia, purpurine was first made at the Imperial Glassworks by Leopoldo Bonafede (1833-1878).  Beginning around 1890, Fabergé's workmasters began using a purpurine of an entirely different formula and it has been suggested that the formula might have been provided to him by Sergei Petukhov, a chemist at the Imperial Manufactory. Petukhov, who retired from the Imperial Glassworks in 1878, may have done some work for Fabergé since H.C. Bainbridge, Fabergé's English agent, names him as the inventor of the material (see H.C. Bainbridge, Peter Carl Fabergé: His Life and Work, London, 1949, 54).
