The Lomonosov porcelain factory was founded in 1744 in Saint Petersburg, Russia. The products were exclusively made for the Russian ruling family of Romanov, and the Imperial Court. Production for sale only started about a hundred years later. Eventually the factory came to be known as the Imperial Porcelain Factory, or IFZ.
Figurines as well as table-ware crockery were produced by the factory. The designs were hand-painted and some were embellished with 22 carat gold. Lomonosov porcelain is exhibited in museums and is gaining popularity as a collectible.
