Penny creates work that explores the subtlety of the hollow form. Her interest in bone china is to create carved forms with variable areas of translucency, exploring the possibilities of light and shade, sometimes incorporating opaque areas with additional colour.

She makes moulds in which she casts forms enabling her to make very thin fine walls, often using layers or inlays of different coloured slips. The forms are then hand carved and finely sanded to achieve a natural smooth "pebble" like quality. She often make forms that link together as pairs.

Heather studied for a BA in ceramics at Central St. Martins followed by an MA at Goldsmiths College, London. Her work has appeared in numerous publications including Homes and Garden and Ceramic Review.
