Note: The term has been disputed among the CAST:ING members. Depending on discipline and expertise, some initially preferred “wax working model”, “wax intermediary model”, or simply “wax”. The current term was finally agreed upon. An inter-model is a type of ‘casting model’ or ‘foundry wax’. However, the latter two refer to any wax model that is destroyed during casting, including those used in the direct as well as the indirect lost wax casting processes.
