Gunn explores an original technique of building layers of gesso, incorporating a gelatine binder with natural earth and mineral pigments and base substances such as chalk, coal, and marble dust. Cracks and fissures, typically considered a defect in the gesso surface, are induced in the work that are beyond the artists control.
She describes her art as 'a pre-occupation with the process of provoking accidents during the stages of making the work... I subsequently perform, in essence, a semiotic action of retrieval by mending and repairing the damage. The main cracks in the works appear during the drying stages and secondary scrapes and nuances are the consequence of the repairing act. They betray the vigour of the rubbing and polishing action. I believe it to be an expression of spirit, vulnerability and survival.'
The absence of imagery allows a pure meditation of the surface and material as a poesis, in the fundamental sense, a movement of coming into thought of the process of making.
Gunn studied at Bolton School of Art and Norwich University of the Arts. She has exhibited widely and held a number of solo and group exhibitions at venues including Norwich Castle Museum and Art Gallery, Rollo Contemporary, The Fine Art Society and the Royal Academy. Her work is held in public and private collections around the world including the China Academy of Art Museum, the Madison Museum of Fine Art, the Sainsbury Collection at the Sainsbury Centre for Visual Arts, the East Anglian Art Collection, the Sovereign Art Foundation, the Priseman-Seabrook Collection, and the The Yale Centre For British Art in the USA.
