All words and pictures Andy Bergholtz . First, I warm up the Castilene in a microwave and work it in my hands like clay, applying the warm Castilene to the sculpture (Fig. 1) After I achieve the basic form using just my fingers, I'll then heat my sculpting tool and smooth the surface (Fig. 2, Fig. 3) I will continue to heat the tool during this process every few seconds, holding the tool very briefly over the flame. I will continue to refine the surface with this tool until I get a basic flow of detail that I like (Fig. 4, Fig. 5) Next, I will gently heat a small loop tool over a flame (Fig. 6), and will use this to carve some deeper detail into the form (Fig. 7). I will do this briefly, just to add a bit more depth to the form (Fig. 8) Next, I will very briefly heat a sanding pad over the flame (Fig. 9), and use this to smooth the surface a bit (Fig. 10). For this stage, you must heat the pad over the flame for only a half-second or so each time, VE...
