Morphology

iron + putty

The noun is a straightforward compound: 'iron' + 'putty' denotes a type of putty associated with or containing iron (iron oxide). A B1 learner who knows 'iron' and 'putty' will readily infer it is a specific kind of putty used for metal/repair purposes even if they do not know the precise chemical ingredients or technical properties.

Etymology

Iron putty comes from how the material looked and was used: craftsmen mixed iron powder like rust with boiled linseed oil to make a soft, paste-like putty that could be pressed into cracks. That's why iron putty now means a tough, 'acid-resistant' sealing paste used to fill and protect metal parts.
