The face of the Buddha is one of the most well known and iconic images in the world even though representations of his face vary widely from one Buddhist culture to another. In common is the sense of peace and liberation that we all desire.
Many Indian Statues are made by the lost wax process in which a wax sculpture of an image is covered in clay which is then baked. The wax melts away leaving a negative image of the sculpture inside the hardened clay. Molten metal is then poured into the mould.
