A very thin layer of acrylic resin was applied to the Berlin cast to protect it from any possible damage, then silicone rubber was brushed over its surface.

Modelling clay was used to make a barrier between the two halves of the mould. When the first coat of silicone rubber had dried, a second, thicker coat was applied with a spatula.
