The Russian porcelain by Vinogradov had qualities similar to Meissen porcelain, while its formula (which consisted of only Russian ingredients) took its style from Chinese porcelain. At the beginning of the Vinogradov period, the motifs were monochrome and simplified; by the end of this period, the fine miniatures were completed on porcelain. Gold leaf for gilding porcelain was prepared from golden coins from the Imperial Treasury.
