The Padmanabhaswami Temple in Trivandrum is a stockroom of fine sculpture. Kerala is blessed with granite which is mainly used in image-making and Changanur is an important centre. The community that makes the images is known as Kallasari. The polishing is done with sealing wax and steel powder which are melted and moistened.

The special variety of stone used for image-making is known as Krishna-shila which is accessible at only one place, Trithala near Pattambi.
