PoYo Putty

This grey, gooey silicone putty feels quite flesh-like and sweats an oily compound from its surface. Composed of two parts that you mix together, it's very sticky when wet, bonding to itself and other silicones, but cures to become a strong rubber in a couple of minutes. It can be used to create a quick and simple press-mould that sets around your object of choice and can then be used for casting exact replicas. It has been used to make moulds of valuable antiques and archaeological models. Wax, gypsum and a variety of resins can then be cast into the PoYo moulds to make replicas.
