Originally, her reputation was due mainly to her pioneering ceramics and installations, which had completely abandoned the container form that had so long dominated studio pottery. But for the last 25 years Nanning has worked chiefly in a different medium: glass, in which she has created an amazing and multi-faceted oeuvre. Each year she spends an extended period in the Czech Republic, where expert glassblowers help her to conjure up the most extraordinary and thrilling objects in that material.
