In 1966 Caziel had his first one-man show at the Grabowski Gallery in London but remained a resident in Paris. Adhering to Abstraction since 1951, Caziel had shown at the Salon de Mai alongside Vasarely, Manessier and Hartung. His Abstraction developed spontaneously from his 1940s investment in Cubism. In 1951 there was no turning back, despite the protestations of his friend Picasso and his dealer Daniel-Henry Kahnweiler.

Caziel would strive to paint works which bring about a spontaneous rush of emotion and the intangeable feeling of the senses. Not unlike an alchemist, Caziel combined colours and shapes in order to evoke a confrontation with the essence of being; his works do not defy description, but should ideally be used to bring one in a transcendental state.
With his abstract works, Caziel demonstrated that his goal was to understand experience by describing its genesis, the process of its emergence from an origin or event. As such Caziel's abstract paintings are inscribed into the contemporary French philosophical debate.

Caziel's works are present in the collections of the Musée National d'Art Moderne, Paris, Centre Pompidou; Vatican Museum, Rome; National Museum, Warsaw, Lodz Museum, Lodz.
