Floating the Sculpture and Preparing for Snap Moulds

Floating the Sculpture and Preparing for Snap MouldsA plastiline sculpture of a prosthetic makeup that has been done on a plaster cast prepared with a water-soluble separator will need to be “floated off” in order to prepare it for final moulding. Here we show the steps of both floating off and of preparing some of the sculptures for taking snap moulds which enable us to create overlapping appliances.
