How its is made :
The buddha face statue is made by the lost wax process. Lost wax casting is a process for making metal statues in which a wax sculpture of an image is covered in clay which is then baked. As the clay is heated the wax melts away leaving a negative image of the sculpture inside the hardened clay. Molten metal is then poured into the mould. When the metal gets cooled the clay casing is broken away to leave the metal image.
