Surface Forms

unvulcanized positive

Morphology

unvulcanized = vulcanized (transparent) = un + vulcanize + ed

Formed by adding the negative prefix 'un-' to the adjective 'vulcanized' (from the verb 'vulcanize'), so the meaning 'not vulcanized' is directly derivable.

Etymology

Unvulcanized is built from un- meaning 'not' and Vulcan, the Roman god of fire; to vulcanize rubber means to heat it with chemicals so it becomes hard and strong. So, unvulcanized rubber is rubber 'not' treated this way, and it stays soft and sticky.
