LOMONOSOV PORCELAIN MARKS - Identification & values reference


Join the most updated and complete collectibles research online - Learn more...


Lomonosov porcelain marksLocated at St. Petersburg (Leningrad), Russia, and established in 1744, Lomonosov continues to be one of the most remarkable Russian porcelain factories, whose fame is the envy of many competitors in other parts of Europe and definitely the desire of many a collector.

The company was awarded its highest status as an official purveyor of chinaware & decorative porcelain to the imperial palace in 1884, deservedly acquiring the name IMPERIAL PORCELAIN FACTORY. After the revolution of 1917 and upon the new political order of the Soviet Union, it was renamed STATE PORCELAIN FACTORY and again LENINGRAD LOMONOSOV PORCELAIN FACTORY in 1925. The simple use of LOMONOSOV to refer to this company was formalized in 1993 but it soon reverted to and is now officially known as IMPERIAL PORCELAIN FACTORY - LOMONOSOV again since 2005 to Present.

Identifying Lomonosov porcelain marks is key to determining the date of manufacture as their logos and backstamps have changed dramatically over the years. Many Lomonosov items are also signed by a decorator or artisan that worked on these pieces, especially on unique centerpieces or grand china services, often made to order for wealthy clients. Imperial monograms also appear often on high quality 19thC Russian porcelains, that provide yet another clue and refer to the period they were produced.
