John Kiley在他的玻璃雕塑中着重强调使用玻璃的几何形态。他以球形为基础，利用并列的颜色和雕刻的视觉通道创造了一个空间的分离，让观者可以观察和通过这个形式。通常，他的雕塑都是边缘平衡的，似乎不受地心引力的影响。艺术家的分形图系列对材料采用了一种更概念化的方法，利用不同的方法对光学玻璃块进行切割。

Artist John Kiley uses primary geometric forms as the architecture for his glass sculptures. In his spherical forms, juxtaposed colors and carved optic passageways create a separation of space, allowing the viewer to peer into and through the form. Often his sculptures are balanced on edge seeming to defy gravity. His Fractograph series takes a more conceptual approach to the material. Different methods including impact and thermal shock are used to shatter a perfectly polished optic blocks. The sometimes-powerful explosion are filmed in slow motion and exhibited along with the reconstructed blocks.
