Casting a Clay Model
in the previous tutorials i have repeatedly spoken about, how important it is to have good references… also, i spoke about using clay models to guide the carving… however, a clay model is soft, and when repeatedly measured on it, it looses shapes, so a way out of this is to cast it in plaster. this is what i want show here in this tutorial. of course, this casting of the clay model is not only limited to the use as a firm model for carving, but one can use it as a finished work, and paint it in faux bronze, or faux marble or whatever one likes to …
i am going to make the mould in plaster, and after that cast in plaster too. doing the mould in plaster, requires that the clay model is soft. since my model is made from plastilin, it will stay soft forever. if you use a model from waterbased clay, you need take care that the model stays soft enough while creating the mould, otherwise, it might be impossible to remove the clay from the mould.
also, the method i am using is not for the faint heart, since the clay model gets destroyed in the process, and usually the mould is destroyed after the first cast too. so, it means, one gets one good cast or none at all… and, i should say, i am pretty new at doing moulds, but i like to share what i learned so far,,,so, if you see things i could improve, please let me know
ok, let´s start ….
