The use of silicone rubbers in the preparation of casts from natural fossil moulds

  • S. R. A. Kelly (a1) and A. McLachlan (a2)
Summary

Techniques are described for the preparation of flexible casts of macrofossils preserved as natural moulds. Materials are discussed and the choice of two high-cost silicone rubbers justified.
