By employing a version of industrial slush casting to conventional silicone rubber moulds and simultaneously applying internal pressure, accurate epoxy resin casts may be obtained, varying by less than 1.0% from the original. This is made possible by the construction of a machine which rotates the moulds through all axes.
When applied to fossil crania these moulding and casting methods not only accurately reproduce the external morphology, but when access permits, simultaneously copy the endocranium. The dimensional accuracy is reproduced throughout for any given measurement.
By using a variety of colouring methods these casts also produce replicas which closely approximate the appearance of the original.
