The main principle within his work is to create a sense of time and movement within a permanent object. Joseph has a fascination with turning one thing into another, the reaction of materials and energies acting upon each other. He uses a direct approach with the modelling material to provide an energetic, spontaneous working method and creative mindset. This energy lives on within the work, giving a sense of progression and evolution within a solid permanent form. He has developed a unique working method using ice as a modelling medium. The ice is eroded and sculpted with salt then cast into glass, capturing a moment in time as the ice is melting. This thawing of ice provides a physical time frame to work within, heightening the importance of artistic judgment and decision-making.
