putty: [17] Etymologically, putty is something that comes from a pot. It was borrowed from French potée ‘contents of a pot’, a derivative of pot ‘pot’. By the time English acquired it, it had come to be applied to a powder made from heated tin, used by jewellers for polishing, and for a cement made from lime and water, used as a top coating on plaster – both substances made in pots. The latter led on in English in the 18th century to the now familiar application to the window-pane sealant. => pot
