Visiting Moscow in 2000, I bought a strange silver-plated object at the antique market "Izmailovo". A rather small container in the form of a traditional wooden Russian barrel with two compartments inside; the upper one bearing a glass inset, was placed on the silver-plated dish and covered by the lid. All three parts (the container, the lid and the dish) were marked by the same monogram AH (AN in Russian). Many of my Russian friends and colleagues could not recognise the purpose of this object. It took me a lot of time before I understood what it was for - it was a caviar holder.
 

Indeed, the caviar is a rather delicate product, easily deteriorating at room temperature. At that time there were no refrigerators, and to protect the caviar the ice was placed in the lower compartment of the container under the glass inset with the caviar. The maker mark easily readable on the container and on the dish was “FRAGET”. Interestingly, a double-headed eagle (the Russian coat of arms) was placed above the mark. After further investigation I recognised that this caviar holder was made in Warsaw (Warszawa), which in the XIX century was the capital of the Polish Kingdom (Królestwo Polskie), an autonomous region inside the Russian Empire. At the end of the XIX century most of the Russian silver plate production was concentrated in Poland, and about ten foundries producing silver plate were operating in Warsaw. Among them the most interesting Art Nouveau objects were produced by “FRAGET” and by another Warsaw foundry, “NORBLIN”. Below are the photographs of some Polish/Russian silver-plated items in Art Nouveau style from my collection.

Now a few words about the history of such a fruitful Polish/Russian trade. The Fraget factory was founded by two French businessmen – the brothers Alphonse (Alfons) and Joseph (in Polish, Józef) Fraget in 1824. However, after 1841 Joseph Fraget became the sole owner of this company. In the fifties-sixties of the XIX century, the firm turned to the production of electroplated silver items and exported them mainly to the Russian market. The products of the Fraget firm soon turned out to be extremely popular. Since, any silver-plated item in the Russian Empire was called simply “fraget”. In 1867 Joseph Fraget died, and his business was inherited by his son Julian. In 1905, Julian was assassinated and from 1906 Fraget was managed by Julian’s daughter, Maria Antonina, who died in 1934. In 1939 with the start of World War II, the Fraget company stopped its activity.
The Norblin factory was founded in 1809 by the goldsmith Filip Vorbrodt, who came to Warsaw from the small Anhalt Principality in Germany. His daughter, Henriette Leopoldina Augusta, first married the French silversmith Jean Cerisy and then (after her hudband’s death in 1831) another French jeweller Vincent (in Polish, Wincenty) Norblin, the son of Alexander Jean Norblin, owner of a bronze factory in Warsaw. Vincent Norblin (1805-1872) significantly increased the production of silver and bronze items and organised the silver plating. In 1865 he sold the factory to his son Ludwig (in Polish, Ludwik) Norblin (1/2 of the whole capital), daughter Albertina Wilhelmina (1/4 of the whole capital) and her husband A. Teodor Werner (1/4 of the whole capital), who was the owner of another silver foundry in Warsaw. After that, Ludwig Norblin and Teodor Werner united their factories in one large company NORBLIN i Ska (NORBLIN i Spó-ka), which means in English NORBLIN & Co. However, they continued to work separately, Ludwig Norblin was producing electroplated silver items, while Teodor Werner worked with sterling silver items. In 1872 Ludwig Norblin (1836-1914) bought a silver plate company from Buch Brothers. In 1893, he organized a new public company  Norblin, Buch Brothers & T. Werner . Like Fraget, Norblin company also successfully survived World War I, but stopped production in 1939.
Below, I am presenting silver plate marks of Fraget and Norblin factories, issued in the XIX - XX centuries.
