Relic restorer

Zhang Guangmin has worked as a restorer of bronzes at the Shanghai Museum for 37 years.

He built a hemispherical framework before slowly piecing each piece together to restore it to its original shape. That part of the process took more than 10 years.

Every time after adding a new piece to the frame, restorers had to wait for a few months before adding another piece.

"Metals have their own strength and resilience," explains Zhou. "You have to make sure a piece is well settled in place, before patching on the next - that's the only way to make sure every piece fits perfectly. You can't rush things."

Zhang and his colleagues explored various ways of reconstructing the treasure, as there is no existing technology available. Bronze as a material for sacrificial vessels is unique to China.

"We went to many precision machinery fairs, and made use of jewelers' and even dentists' tools. You have to be inventive, and find solutions to your problems. You need to cut out the pattern in a perfect angle and join it with the existing part - it's like a jigsaw puzzle, but you have to create all the missing pieces," he says.

Zhang is thankful to the Art Conservation Project of Bank of America Merrill Lynch, an initiative to help conserve important works of art and cultural treasures all over the world. This year the project was in China for the first time.

Zhang got connected to the organization and acquired an ultra-sound knife - which was meant for jewelry designing.

"The knife made my work much easier, and helped me complete the restoration faster than expected," Zhang adds.

When the original pieces are reshaped, Zhang had to fill in the missing gaps with low-temperature welding, "to make sure it can be undone easily, if needed," Zhang says.

Then came the most difficult part: to reproduce the intertwining dragon patterns.

The patterns are intricate, purely handmade and more than 2,000 years old, on a surface of no more than 1 millimeter at its thinnest.

"It's not mechanical repetition. With every touch, our human hands will unavoidably leave traces of slight differences," Zhang explains.

Members of the public will be able to admire the finished work next year, after the bronze exhibition hall is refurbished at Shanghai Museum, says Chen Kelun, deputy director of Shanghai Museum.
