Philanthropic Londoners are supporting the Evening Standard’s campaigns to encourage London primary school children to read more and to find young adults work through apprenticeship schemes. This culture of selfless giving is a vital part of London life. Visitors to the British Museum have benefited greatly from this generosity, which manifests itself in new buildings, refurbished galleries and acquisitions of new objects.

Jimmy Riesco (1877-1964) from Croydon was one such benefactor. He collected Chinese art and bequeathed his collection of Chinese ceramics to his home town, where it is now on display in the Riesco Gallery in the Museum of Croydon. This magnificent cloisonné jar, a testimony to the quality of Chinese craftsmanship, was once in his collection. It is decorated with powerful dragons with snake-like bodies and horns flying through the clouds.

Cloisonné is a method of decorating metal objects with a network of wire cells. Cloisonné wares are particularly time-consuming and labour-intensive to make. Craftsmen sketch a design onto a metal jar using a brush and black ink. Wires are cut out of sheet copper and fixed to the body of the jar, forming cells. The cells are filled with multicoloured opaque glass, which produces a brightly coloured surface. The jar is then fired in a kiln at about 600 degrees centigrade. After firing, the jar cools and the glass shrinks. Any gaps in the design are filled in and the jar is refired. This process is repeated up to four times. Finally the jar is polished and the metal wires gilded.

From two inscriptions around the rim of this jar, we know who commissioned it and where it was made. Zhu Zhanji (1399-1435), the Ming Emperor from 1426 to 1435, commissioned it and eunuchs in the Forbidden City Palace in Beijing supervised its manufacture. Ming Emperors ordered such brightly coloured objects to decorate the vast halls of their palaces. The magnificent dragons were symbolic of the emperor. As you can see from walking around Chinatown today, dragons continue to be a powerful symbol of good luck.

There is only one other jar like this one in the world. It is in Switzerland in the Reitburg Museum, on loan from a private collection. Originally the two jars would probably have been displayed together in the Forbidden City Palace. The British Museum plans to reunite the jars in an exhibition beginning in September 2014, which will show the splendour of early Ming courts and the extraordinary connections that Ming China established with the rest of the world. [Note: This was not in fact possible, and the two jars are not displayed together in the exhibition. 22 September 2014]

This was first published in the London Evening Standard on 11 October 2012.

To celebrate our partnership with @googleartproject, we’ve asked members of British Museum staff to highlight their favourite objects and explain what makes them special. Jill Cook, Deputy Keeper of Britain, Europe & Prehistory, chose this stone chopping tool from an early human campsite in Olduvai Gorge, Tanzania. ‘Holding this 2 million year old African tool in my hand I am reminded that whatever differences exist between people now, we are united by our common origin in Africa. The discovery of this piece by Louis Leakey in 1931 began to change our understanding of what makes us human. It illustrates the beginning of a transition from an ancestral ape that walked upright on two legs within the confines of a limited ecological niche to humans with more complex brains capable of changing and eventually dominating the world around us by making tools and weapons. This chopping tool is one of the seeds from which all human cultures and societies have grown.’ Discover the stories of thousands of objects in the Google Cultural Institute at

#MuseumOfTheWorld In Victorian England many people were fascinated by their past, and the ancient tribal leader Caratacus (also spelt Caractacus) was adopted as a symbol of national pride and independence. Like Boudica, Caratacus resisted the Roman invasion of Britain. Although he was eventually defeated, he earned a reputation as a noble and worthy foe. The Victorian sculptor J H Foley portrays him here standing triumphant, the embodiment of courageous English spirit. See this incredible #Movember moustache in our #Celts exhibition, until 31 January 2016.
J H Foley (1818–1874), Caractacus. Marble, 1856–1859. On loan from Guildhall Art Gallery/Mansion House, City of London. Some more #Movember inspiration! Here’s the Museum’s security team from 1902 photographed on the front steps. They include officers from the Metropolitan Police, and the London Fire Brigade (identified by their flat caps). We’re celebrating #Movember with Museum moustaches great and small. Here’s a #Movember fact: Peter the Great of Russia introduced a beard tax in 1698 and this token was given as proof of payment! Our unique new partnership with Google's Cultural Institute @googleartproject now allows you to virtually walk through the whole Museum! The British Museum is the largest space ever to be captured on indoor #StreetView, putting the unparalleled world collection at your fingertips. Come and explore!
