- Maybe we should discuss the whole class in the same time. Taking a look at other similar entries, for example tin, cotton, wool and wood have "made of ~" as sole adjective sense. Copper, bronze, silver and gold are recognized as colours, but they also have a "made of ~" sense listed, whereas zinc, clay, cloisonne, enamel, steel and aluminum do not feature an adjective section at all. In iron the adjective sense is recognized under separate etymology (!) and it has the sense "strong" in addition to "made of ~". Plastic has a lot of adjective senses, among them "constructed of polymer". Also brass has many adjective senses but "made of ~" is not among them. --Hekaheka 07:54, 7 January 2012 (UTC)
