Pushing the Limits

"Norman Foster wanted a surface like no one has ever seen," said Zahner, referring to his work on the British architect's spaceport in New Mexico. At the time, Zahner and several of his engineers had been experimenting with heat, exposing different copper alloys to temperatures around 10,000 degrees. "Portions of the alloy constituents come out, and you get these really wild looking surfaces," said Zahner, before pausing. "I don't know if he likes them yet."
