• Her profound understanding of the geometric rules governing any given pattern, allow her to bend, or even break them.
    – Peter Randell-Page, Sculptor

  • I love this artist’s work. How she keeps her molten flowing themes through different media – stone, concrete, wood and even glass. Long to touch them. What a unique eye and hand she has. Wonderful.
    – Maureen Lepman

  • …Although Cassell is creating in different media – and respecting the unique characteristics of her material while doing so – she is also intent on discerning just how bronze, glass, marble and clay can ‘speak the same language
    – Ian Wilson

  • The geometry and the mathematics involved in Halima’s work have the same effect on me as listening to Bach: she manages to get the same essential harmony of shape, form and detail. Her pieces are deeply fashioned, which is unusual in ceramics
    – Eric Knowles (Ceramics Expert)

  • Beautiful – amazing to see someone work with such a variety of material to create such stunning, intricate pieces. I can imagine them out in the world, near water and nature. Beautiful, thank you.

  • Cassell’s work encompasses and generates complexity and surprise. All of her sculptural work shares a language of geometry and volume but each is intriguingly different
    – Elli Herring

  • She was sketching constantly and continually sought to transpose her drawings into sculptural forms. The surface as well as the shapes emerged together in sculpture which often combined enormous complexity with simplicity and unity.
    – Helaine Blumenfeld OBE FRBS Dlitt

  • The most inspiring ceramic work I have seen in thirty years! Beautiful, mesmerising, powerful and thoughtful. Genius! Love, love, love this work.
    – Judith Ramsgate, 53 years old

  • While working, Cassell becomes deeply involved in each piece to the point where she is unaware of her surroundings even watching her work on a piece for a few minutes, it is obvious that the process commands all her attention
    – Emmanuel Cooper

  • She set very high standards for herself and was tireless in her efforts to reach them. After just three months she was able to carry out complex, compelling, delicate and dynamic work.
