The Imperial Porcelain Factory (Russian: Императорский Фарфоровый Завод, romanized: Imperatorskii Farforovyi Zavod), also known as the Imperial Porcelain Manufactory (abbreviated as IPM), is a producer of hand-painted ceramics in Saint Petersburg, Russia.

It was established by Dmitry Ivanovich Vinogradov in 1744 and was supported by the Russian tsars since Empress Elizabeth.

Dmitry Ivanovich Vinogradov, a talented mining engineer who studied metallurgy at Freiberg, Saxony, developed the formula for the first porcelain manufactory in Russia, established in 1744 by order of Empress Elizabeth, daughter of Peter the Great, to "serve native trade and native art.

"[1] For a long time, the factory produced wares almost exclusively for the ruling Romanov family and the Russian Imperial court, and for political and diplomatic gifts by them.

These last continued until the Revolution, and largely replaced the repertoire of pastoral, gallant, and commedia dell'arte figures familiar from factories in the rest of Europe.

During the reign of Paul I (1796 to 1801), Russian porcelain continued to develop in style of Neoclassicism, with the increasing influence of Hellenic and Roman motifs.

Masters from the Königliche Porzellan-Manufaktur Berlin and porcelain painters from the Manufacture nationale de Sèvres were invited to Saint Petersburg, and the kiln chamber was restructured.

Porcelain was produced with whimsically curved forms decorated by stylized plants, mermaids and other Art Nouveau motifs.

All the fine porcelain items produced were sold at charity auctions benefitting the Royal hospitals.

[3] The newly christened Lomonosov factory produced a range of wares, including collectible animal figurines and dinner sets.

The design is based on a blue net pattern that was painted on raised lines cast into the porcelain dinnerware pieces of Catherine the Great.

[4] There is also a version that artist Anna Yatskevich, the author of the famous cobalt net, painted a set in memory of the cross-glued windows of houses and the cross-light of searchlights that illuminated the sky of besieged Leningrad.

At that time, wide exports began to countries unfamiliar with Lomonosov wares, particularly the United States and Japan.

After 2002, a new export backstamp appeared which featured a red or blue LFZ monogram along with the words "Hand Decorated, 1744, St. Petersburg, Russia".
