Cliff Lee: Prickly Melon vases by Cliff Lee, who was a surgeon until he gave up medicine in favor of pottery in the '70s. "Any of the people on my list represents master craftsmanship in some way or another," says Alhadeff. "But the level of detail Lee is able to execute in porcelain is incredible. He’s got little thorns on his Prickly Melon vase that disappear into the air — you can’t even see the point, it gets so thin," he says.
