Iron+&+Steel

About the quotation: “//the old cast iron buildings died out. I'm not really sure whether the new skyscrapers killed them, or the new esthetics//”

Personally, I think John H. Lienhard says that because the new era of modernism needs new material that support the development of the new values of modernism, with the high resistance of Steel, this can be hidden in the buildings in shows the wide windows of glass. On the other hand, steel gives us new aesthetics and opportunities like minimalism facades and big entries of light. So the old tendencies of frilly ornaments died with the revolution of modernism.
