• Cassell’s Work Is Subliminal in its originality, having no parallel in the sculptural or crafts genres, whose borders it crosses.
    – Jean Vacher, Collections Manger, Crafts Study Centre, Farnham

  • 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.
    – Jina

  • 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

  • Her signature material is clay, which she moulds and carves with natural authority and no little dexterity. Her crisply cut and satisfying forms live on in the mind… She is a force of nature.
    – Andrew Lambirth, Art Critic - Spectator Magazine

  • Halima’s work demonstrates incredible dedication and energy; one thing is clear, she will be among the future pathfinders and leaders.
    – Alan Grieve, Chairman, The Jerwood Foundation

  • 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

  • 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.
    – Helaine Blumenfeld OBE FRBS Dlitt

  • 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
