Ann Wolff is best known for her kiln-cast sculptures. She discovered the casting technique when she began to feel that glass as a medium was too limiting for her. Her use of kiln-casting allows her to combine her talent as a sculptor with the difficult medium of glass, fostering a totally new method of expression. Ann's mastery of this technique enables her to create areas of inner luminosity within the glass, thus allowing the viewer to penetrate the innermost spaces of the sculpture.

Ann's work reveals a remarkable degree of strong personal presence in both her graphic works and glass sculptures. Her glass sculptures depict contemplative female faces that resemble African fertility goddesses, as can be seen in works such as Lucifer, 2005. Ann's work in glass serves to express her feelings about the role of the modern woman, a theme she echoes in work such as the Domus series, 2005. Here she explores the name Domus (the Latin word for house or home) in its Classic-Roman connotations, along with the roles of contemporary women as mothers, wives and career women.
