MOULDING DAVID

My terracotta reproduction of Michelangelo's 'David' needed to be cast. The mould was created by layering the sculpture in several layers of fast setting Polyurethane Rubber. The more obvious choice being silicone but being a student I opted to use a cheaper alternative. The rubber was then built up around the edges to create seams, and then covered in several shaped sections of plaster to create the mould jacket or mother mould. In total the mould consisted of 6 sections of the internal rubber and a 12 section mother mould. Leaving clay residue inside the rubber mould before casting in plaster was an artistic choice to create patina. I have also left the seam-lines on the sculpture to highlight the mould shape, as this project was an exercise in process.
