• Her main preoccupation and sculptural impulse is to penetrate beneath the skin of the form to reveal the structure within – the crystalline seed of the stone, or the skeleton-like armature she perceives within the clay. She does not carve exteriors but reveals interiors – the folded abstract inner landscapes of her singular and highly imaginative vision.
    – Andrew Lambirth, Art Critic - Spectator Magazine

  • Working mostly with ‘naked clay’, that is without the use of glaze or slip, Cassell first carefully carves and then smoothes and burnishes to remove any blemishes, so virtually making the surface ‘ disappear’, leaving the form clean and prominent
    – Emmanuel Cooper

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

  • 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 work is of a high standard and creates an interesting contrast to the Da Vinci drawing. Can see the evolution of the process and the sculptures convey different ideas and theories. An excellent artist.

  • 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)

  • …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 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

  • 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.

  • 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
