Statues by the elder Calder get laser treatment

These conservation efforts removed the many years of corrosion built up on the works

Over a century of corrosion has been removed from eight colossal bronze sculptures in Philadelphia by a Chicago-based conservation company. The 70-tonne sculptural group by Scottish-born Alexander Milne Calder, grandfather of the artist Alexander Calder, was installed on the city hall’s tower between 1894-96. Conservation of Sculpture and Objects Studio Inc used laser technology never before applied on sculptures of this size in the US over three and a half years. The city provided around half of the $2m cost while the remainder came from non-profit organisations including Pew Charitable Trusts.
