This series of photographs illustrates the labor-intensive process required to create Valentine’s large-scale polyester resin sculptures. First, Valentine weighed out the precise amount of catalyst to be added to the polyester resin in order to initiate the curing process. The correct proportion of catalyst to resin was critical to casting large-scale pieces.

Valentine then poured the catalyst into large barrels of resin. Along with the pigment, the three components would then be thoroughly mixed together. To ensure complete mixing, Valentine would use a propeller blade that was attached to a motor to stir the mixture in the barrel. Mixing these large barrels of resin would often take up to an hour.

Once mixed, the polyester resin was poured from the barrels into the mold. In one image, we see Valentine in the foreground pushing a forklift, with his two studio assistants on ladders. At the foot of the ladder are the barrels containing the polyester resin that would be poured into the mold. Once cured, the artwork would be sanded and carefully polished to achieve a reflective sheen.
