“I like the clay to speak for itself”, says ceramicist Margaret Curtis, speaking to me at the launch of her new exhibition, Surface, at the Contemporary Ceramics Centre in London. Her pieces, whether they be large vases and cylinders or small bottles and cups, have one thing in common – their imperfection. “I make them in the round, sort of precise, then I start pushing them and poking them and distorting them and let the movement of the clay give a lot of feeling.”
