List the Properties of Ceramics-They are Insulators of Heat & Electricity and are more Brittle [Shatter - able] and Stiff then other Materials -However, they are Strong and can last for a Long Time as they do not Corrode. Hence the Reason you see Ceramics in Windows.
List the Properties of Metals-Metals are Conductors of Electricity & Heat so again, may be an Advantage or Not -Metals are also Malleable [Bendy] so can make Shapes -However, Metals may Corrode or Rust [Iron] but some other Metals are Resistant to Corrosion so they can Last a Long Time -Metals also Up on Ceramics as they won't Shatter as Easily.
