Sad news continues to percolate concerning rusting problems at the Bilbao Guggenheim. This is not supposed to happen, the titanium panels are in theory rust-proof.
But Internet stories suggest that the city's industrial pollution is causing unexpected chemical attack, and that the thinness of the panels is allowing moisture to creep under and on to the steel structure below. Astragal will investigate this in person at the end of the month and report back.
It may be like the stories about rips in the dome factory - grossly exaggerated. Meanwhile rather older structures are also under threat, this time from mould.
According to the China Daily , 1,400 of the 7,000 terracotta warriors in the ancient city of Xian are threatened by fungal attack.
This has prompted a deal with a Belgian chemical company to devise a cocktail of curative chemicals to combat what could be called aesthete's foot.
